Industrial enzymes in bioindustrial sector development: An Indian perspective

Journal of Commercial Biotechnology, Aug 2007

The bioindustrial and information technology sectors have been the two most-decisive factors for the rising Indian economy over the last 15 years. India is the second fastest growing economy in the world, with a gross domestic product (GDP) of 9.2 per cent in 2006–2007. Industrial enzymes production and marketing predominantly cover the developments incurred in the bioindustrial sector. In 2006–2007, the bioindustrial sector made an impressive turnover of Rs. 3950m, with a growth rate of 5.33 per cent. India imports about 70 per cent of the total enzyme consumption. Pharmaceutical enzymes are the representatives of industrial enzymes' demand in India and cover almost 50 per cent of the total enzyme demand, followed by detergent enzymes (20 per cent) and textile enzymes (20 per cent). The global market for enzymes was estimated to be about $ 2bn in 2004 in tune with an average annual growth rate of 3.3 per cent. This article touches upon the importance of major industrial enzymes in the development of the bioindustrial sector in India. Also, applications of enzymes, manufacturing industries and major suppliers or distributors of enzymes have been discussed.

Journal of Commercial Biotechnology (2007) 13, 283–291. doi:10.1057/ INTRODUCTION The Indian economy since 1990 has risen sharply. Today, the economy of India is the third largest in the world as measured by purchasing power parity (PPP) with a GDP (gross domestic product) of US $1.0 trillion upon measuring in USD exchange rate terms.1 India is the second fastest growing major economy in the world after China, with a GDP growth rate of 9.2 per cent at the end of the second quarter of 2006–2007.2 The main driving forces behind this unprecedented success are information technology (IT) and biotechnology (BT).3 IT and BT constitute approximately 5 per cent of the country’s GDP, showing 23 and 40 per cent growth, respectively, during the year 1999–2000. BT covers a very broad range of specialised areas including biopharmaceutical, bioindustrial, bioservices, bioagriculture and bioinformatics. Out of these, the bioindustrial sector, which encompasses the harnessing of microorganisms for the production of value-added bioactive ingredients (industrial enzymes, organic acids, bulk chemicals, single-cell proteins, etc.), has played a predominant role in the overall development of biotechnology after biopharmaceuticals. Both biopharmaceutical and bioindustrial industries generated almost Rs. 35,700 and 4,250m revenue during the year 2004–2005, respectively.4 Table 1 presents the breakup of revenue generated by different Indian biotechnology industries.3,4 In recent years, BT has shown a slow but steady growth and has emerged as an important contributor to world economy. According to Ernst and Young’s 2005 Annual Global Biotechnology Report, the biotechnology sector is one of the fastest growing sectors, with a revenue growth of 17 per cent from 2003 to 2004.5 Recent biotechnological innovations have paved the way for the successful production of various biocommodities at a commercial level that not only improved the product economics but also the environment by replacing the conventional chemical conversion routes. In the country, the role of Government-funded research institutes, universities and private sector is highly remarkable in making BT successful at a commercial level. India has emerged as a major hub for cutting-edge R&D bioindustrial projects for global multinationals such as Novozymes (Denmark), Genencore and Dyadic International (USA) and Quest International (Irish Republic). Recently, the Danish company CHR-Hansen was launched in India for marketing the enzymes applied in food and feed products, while Novozymes recently opened its R&D centre at Bangalore.6 These industrial giants are now aiming towards the development of potent and ‘designer’ cellulases for the cheap and efficient production of bioethanol, the future renewable energy source. Apart from industrial enzyme manufacturers, bioservices and biopharmaceutical companies have shown an excellent turnover in India. Table 2 shows the net turnover of the top 15 Indian BT industries during the year 2004–2005. Worldwide, Europe has considerable assets in the field of industrial biotechnology. In Europe, 70 per cent of the world enzyme industries exist with a high level of 2002–2003 2003–2004 2004–2005 Biopharmaceuticals 17,900 Bioindustrial 2,350 Bioagriculture 1,350 Bioinformatics 1,100 Source: Mani.3 knowledge in the field of food technology and fine chemistry.7,8 Due to an everincreasing labour, energy and raw material costs, more bulk manufacturing companies are, however, moving to the Far East. In the present time of increased industrial development, the impetus of industrial biotechnology in the improvement of any nation’s economy is crucial. A recent Frost and Sullivan study depicts that various contract research models like joint research, collaborative research and complete outsourcing have given the BT sector a successful impetus worldwide. India has the 12th most successful BT industry in the world as measured by the number of companies. The main driving force for commercialisation of BT in India is the Department of Biotechnology (DBT) of the Ministry of Science and Technology. DBT played a vital role in the commercialisation of R&D activities for biotechnology, human resource development and bioinformatics programmes and has declared a new development strategy in 2005 for revenue generation up to US$ 5bn annually and to create one million jobs by 2010.3 Enzymes have been the centre of attention for researchers/industrialists the world over due to their wide range of physiological, analytical and industrial applications. Although enzymes have been isolated, purified and studied from microbial, animal and plant sources, microorganisms represent the most common source of enzymes due to their broad biochemical diversity and feasibility of large-level production by exploiting cheap carbohydrate sources.9,10 This review presents an overview of the current status of the bioindustrial sector in India. Particular emphasis is placed on the Indian enzyme manufactures and suppliers and enzyme applications. MAJOR INDUSTRIAL ENZYMES AND THEIR APPLICATIONS: AN APPRAISAL Enzymes are catalysts, organic compounds produced by living organisms that accelerate the transformation rate of substrate to the end product by lowering the activation energy barrier.11 Although all enzymes are initially produced in the cell, some are secreted through the cell wall and function in the cell’s environment. Hence, we recognise two types of enzymes on the basis of site of action: intracellular enzymes or endozymes (functioning in the cell), and extracellular enzymes or exoenzymes (functioning outside the cell).7 Diastase was the first commercialised enzyme for the production of dextrins in bakeries, beer and wine from fruits in France in 1830.12 In 1874, in Denmark, Christian Hansen started the first company (Christian Hansen’s Laboratory) for the marketing of standardised enzyme preparations, rennet for cheese making.7 In USA, J. Takamine isolated bacterial amylases in the 1890 s at Miles Laboratories. In 1913, Otto Rohm’s patent gave the idea of using pancreatic extract enzymes as washing aids for laundry cleaning and the product was marketed under the brand name Brunus and sold in European markets for about 50 years.13 In the mid-1960s, Novo Industri A/S introduced alkaline protease in the market produced by Bacillus licheniformis under the brand Alkalase.14 Furthermore, in 1985, Novo launched a new multi-enzyme preparation containing -cellulase, alkaline protease and other enzymes, which brought evolutionary changes in the market. In general, an ideal enzyme for detergent preparation should be effective at low levels (0.4–0.8 per cent) in the detergent solutions. Today, proteases are the leaders of the industrial enzyme market worldwide.13,14 Now enzymes have attained the status of a household commodity. Recent developments in the field of enzymology, such as genetic engineering development for recombinant enzymes, search for biodegradable carriers for immobilisation, extremozymes and recently cross-linked enzyme crystals yielding stable enzymes, are more suitable for commercial organic synthesis and their resolution.15 Modern enzyme technology, in conjunction with multidisciplinary scientific knowledge and process technology, is crucial for the development of new, clean and cost-effective manufacturing concepts for food specialty (e.g., bread, cheese, alcoholic beverages, vinegar, fruit juice, etc.), fine-chemical (e.g., amino acids, vitamins), bulk chemical commodities (bioethanol, biodiesel, xylitol, 2, 3-propanediol, etc.), and pharmaceutical and neutraceutical products.16,17 Enzymes also have an application for a wide range of analytical purposes especially in food diagnostics and as sensors in electrochemical reactions. Table 3 presents the major industrial enzymes and their broad-range applications.13,14,18–29 Global sales of industrial enzymes were valued at $2bn in 2004.29 The market for Pharmaceutical enzymes accounted for 41 per cent of the market with food and feed industry (17 per cent) and detergent industry (17 per cent) as shown in Figure 1.30 A recent McKinsey estimate suggests that the total value created by enzymes could be to the tune of $12bn a year by 2010 globally. In India, the maximum demand of enzymes is in pharmaceutical industries, followed by food/ feed and textiles (Figure 2). In India, the bioindustrial sector, which predominantly comprises the enzyme companies, is estimated to be Rs. 3,950m in 2006–2007 and registered 5.33 per cent growth in 2006– 2007.4,30 India imports about 70 per cent of the total enzymes consumed in the country, the majority of which goes to the detergent, textile, starch and pharmaceutical industries. Based on available information, the estimated consumption of industrial enzymes in India in various sectors has been summarised in INDIAN SCENARIO OF INDUSTRIAL ENZYMES’S PRODUCTION In India, the major industrial enzyme manufacturers are – Novozymes India, Bangalore, Biocon India Ltd, Bangalore, Advanced Biochemicals, Ahemdabad, and Maps India, Ahemdabad. Novozymes was the market leader in this segment during 2006–2007, with total sales of Rs. 1,000m. Biocon and Advanced Biochemicals were the other major players with sales of Rs. 950 and 693m, respectively.4 Novozymes, Advanced Enzymes Technologies and Zytex have registered over 20 per cent growth in 2006–2007 against the previous year. Rossari registered over 60 per cent growth while Biocon registered 12 per cent growth over the previous year’s sales revenue. The total revenue generated by the top five Indian enzyme manufacturers is shown in Table 5. Currently, Novozyme is leading all the industrial enzyme manufacturers in India. For the first time, Novozymes is setting up a new R&D laboratory in Bangalore, India. The new facility will initially focus on optimising enzyme properties. It is expected to be fully operational from mid-2008. Biocon India Ltd., Bangalore, is an integrated leading enzyme biotechnology company in India that has gained many accolades worldwide for its strong R&Dbased deliverables towards product specificity Alkaline protease Alpha amylases Glucose isomerase In laundry, dish washing, textile washing, food and dairy industries, glass lens cleaning, etc. In food industries, detergent industries, paper industry and pharmaceutical industries Isomerise glucose to the sweetener molecule and high fructose, Starch liquefaction, glucose–fructose sugar syrup making and ethanol making industries In beta-lactam semi-synthetic antibiotics intermediates production and racemic mixture isolation In food, feed and beverages, pulp and paper industries, detergent industries and bioethanol production In pulp and paper industries, food and feed industries, textile and bioethanol production In food and feed production, fruit juice purification and stabilization, textile industries, retting and de-gumming of fibre crops and quality paper production In dairy and other food processes, detergents, pharmaceuticals, cosmetics, leather processing and production of aliphatic acids In hydrolyzing of tannins, leather processing, wine making by reducing the haze, preparation of cold water soluble instant tea, coffee, etc. In reducing phosphorus excretion of monogastric animals by replacing inorganic phosphates, animal nutrition, processing of human food and environmental protection Delignification of pulp and paper, fine paper making, fruit juice clarification and stabilization, bioremediation, xenobiotic substrate removal, detoxification of plant cell wall-derived sugar syrups. with high output and better reproducibility. The company has a diversified product range from microbial-derived enzymes to generic bulk drug(s)/medicine(s). The company is, however, now focusing more on biopharmaceuticals and is keen to develop some oral drug formulations for insulin and rheumatoid arthritis. According to a very recent report, the company is divesting its industrial enzyme business for Rs 4,670m to Novozymes.31 Advanced Biochemicals Ltd., Pune, has played a key role in the development of the enzyme business in India. The company is dedicated to the production of different microbial enzymes used in pharmaceuticals, neutraceuticals, textiles and distillation. The strong R&D setup of the company prevailed to launch new novel enzymes with greater efficiency, less specificity and fast conversion rates with high reproducibility. The company is engaged mainly in the production of alpha-acetolactate decarboxylase, alpha amylase cellulase and alkaline protease. The company is setting up a manufacturing facility at Indore with an investment of Rs 150m. The company has set aside another Rs 350m for its expansion. Source: Biospectrum.4 Revenue (Rs. millions) Source: Biospectrum, March, 2006 ( Maps India Ltd., Ahmedabad, has produced microbial-derived industrial enzymes since 1975. Their main products are palkoenzyme (alpha amylase) and palkobate (alkaline protease). The company has a strong marketing strategy to capture the domestic users as well as the foreign market. Mumbai-based Rossari Biotech Ltd. is offering the enzyme solutions for textile auxiliaries. The company has, however, also recently ventured into newer areas like food, feed and paper starch-based enzymes. Fermenta Biotech Ltd., Kullu, Himachal Pradesh, has been a pioneer in penicillin acylase production to meet the requirement of pharma companies for the production of beta-lactam antibiotics in India. This company is now focussed on other enzymes such as- Fermase OX 1500, Fermase PA 1500 and enantio-selective enzymes like the R- oxynitrilase enzyme, which is used in the preparation of high-value optically active intermediates. Kopran Drugs Ltd., Mumbai, manufactures semi-synthetic penicillins and is among the world’s highest producers of amoxycillin. The company also makes penicillin acylase for its own requirements to synthesise beta-lactam antibiotics. Concord Biotech Ltd., Ahmedabad, is also involved in the production of penicillin acylase and other hypolipaemic products such as lovastatin, pravastatin, simvastatin, etc. The company’s main product is penicillin acylase and has exported the enzyme to China and European countries since 2000. Dalas Biotech Ltd., Bhiwadi, Rajasthan, has played a key role in the fulfilment of penicillin acylase supply to beta-lactam antibiotic manufacturers. The company is also looking for the production of glutaryl-7ACA acylase and D-amino acid oxidase, which play a key role in the biotransformation of cephalosporins into 7-amino cephalosporanic acid and glutamic acid. Osten Enzyme India Pvt. Ltd., Chennai, manufactures, supplies and exports enzymemediated oil, bioadditives commonly used in refineries, industries and automobiles in India and abroad for pollution control, savings on fuel oil and environment protection. Hyderabad-based Celestial Labs Ltd. has started enzyme production after establishing its state-of-art production facility at Shameerpet Industrial area, Andhra Pradesh. The company has selected today’s two most common industrially important enzymes, alkaline protease and alpha amylase, for their production at the envisaged capacity of 20 KL fermenter scale. The company has a technical tie-up with Institute of Microbial Technology (IMT), Chandigarh, one of the most reputed and premier research organisations in the country. In India, IMT, Chandigarh, has standardised cost-effective, value-added and eco-friendly production technology for the alkaline protease and alpha amylase using submerged fermentation. Another alkaline protease preparation has been developed by Central Leather Research Institute, Chennai, under the trade name Clarizyme.32 In the country, considerable research work on Penicillin G acylase has been carried out at National Chemical Laboratory (NCL), Pune, Hindustan Texnzymes India, Mumbai, Maharashtra Americos Industries Inc.,Ahmedabad, Gujarat United Biochemicals Private Limited, Mumbai, Maharashtra Ruchi Biochemicals, Mumbai, Maharastra Trishul Chemicals, Chennai,Tamil Nadu Manufacturers Manufacturers And exporters Manufacturers and exporters Manufacturers and suppliers Manufacturers and exporters Indian Textile Auxiliary Co., Bangalore, Karnataka Manufacturers and exporters Zytex India Private Limited Mumbai, Maharashtra Naruveli Ventures Chennai,Tamil Nadu Enzyme India Private Limited, Chennai,Tamil Nadu Manufacturers and exporters Monozyme India Limited, Secunderabad,Andhra Manufacturers and exporters Pradesh Prasanthi Leather Chem Private Limited, Kolkata, Wholesale suppliers/Distributor West Bengal sellers Biomax,Thane, Maharashtra Manufacturers Genotex International Private Limited, Hyderabad, Manufacturers and exporters Andhra Pradesh Protos Trading Private Limited, New Delhi Importers/buyers Textile auxiliaries and enzymes Textile auxiliaries and enzymes Enzymes and biochemicals for textiles Enzymes and fat liquors, etc. Antibiotics Ltd., Pimpri, Pune, and Madurai Kamraj University, Madurai.

Cellulases have been focused upon at IIT (Indian Institute of Technology), Delhi. Alkaline pectinase has been the area of research at Microbiology Department, Panjab University, Chandigarh. Apart from the abovementioned research centres, other laboratories are also engaged in enzyme research and are doing well. A description of the details of each research centre is beyond of the scope of this paper. ENZYME DISTRIBUTORS/ SUPPLIERS IN INDIA Today, the Indian biotech sector has attained critical mass in manufacturing and research services. Indian biotechnology is now poised to leverage its scientific skills and technical experiences to make a global impact on a strong innovation-led platform. The technological capability of a firm to produce some products is only a part of the requirement for the commercial success of the business. Apart from technological capabilities, the firm must be able to position its product in the market. The market, thus, serves as the link between consumers’ needs and the pattern of industrial response.33 Table 6 shows the potential enzyme distributors/suppliers in India. There are, however, several enzyme distributors in the country, but here we briefly summarise the main and potential ones. Their role is highly specific in upgrading the successful commercialisation status of industrial enzymes. The role of the direct distributors/supplier is to promptly supply enzymes to the end users. FUTURE SCENARIO OF INDUSTRIAL ENZYMES IN INDIA With the advent of biotechnology, there has been a growing interest in and demand for enzymes with novel properties. Enzymes from marine microorganisms have unique properties and have proven their industrial applications.34 Other special enzymes are thermo-tolerant enzymes, which have shown enhanced stability even under highly stringent conditions. These enzymes provide unique advantages like greater stability during the substrate conversion, which results in more conversion cycles, thus saving energy and time.35 Genetic engineering is of central importance for the development of novel genetically modified or ‘designer’ enzymes. India is still fulfilling its enzyme demand by importing to the tune of 70 per cent from US, Canada and China. Looking into the increased demand of enzymes in the future, a nationwide production development programme needs to be initiated with support from the government and private sector funds. Future achievements will include a much greater appreciation of structure–function relationships in enzymes, screening of novel and high enzyme titre-yielding strains, improvement in production yields adopting statistical approaches and improvement in downstream recovery of enzymes, etc. CONCLUSION Enzymes can be considered as green chemicals; they have very wide applications and can be referred to as household commodities owing to their role in today’s human activities. The government of India through the Department of Biotechnology (DBT), the Department of science and Technology (DST) and the Council of Scientific and Industrial Research (CSIR) has been considerate to the bioindustrial sector, and funding projects related to industrial enzymes. This will help the industry grow, launch new products and compete with global players. Enzymes have a significant role in the production of biofuels- the fuels of future. Cellulases, xylanases and amylases act on cellulosics and starchy substrates to yield a cocktail of carbohydrates that can be converted into motor fuel (ethanol) after fermentation with appropriate microorganisms. India still imports 70 per cent of its enzyme requirements from the US, Canada and China. If more research and entrepreneurship attention is focused on in-house production of enzymes, it will create more employment and income, which can expedite the new ways of saving the foreign exchange reserves. The bioindustrial sector, which mainly comprises enzyme production companies, is estimated to be Rs. 3,200m in 2004–2005 and has an influential impact on the country’s economic growth. Among the Indian enzyme manufacturers, Novozymes ranks top by generating a revenue of Rs. 1,000m followed by Biocon (Rs. 950m) and Advanced biochemicals (Rs. 693m) during the year 2006–2007. To summarise, industrial enzymes have played a significant role in today’s commercial status of biotechnology in India. The future will witness more and novel applications of microbial enzymes in far greater areas than what we could anticipate today. Acknowledgments We thank Dr A.N.
