The short-run effects of knowledge intensive greenfield FDI on new domestic entry

Existing evidence on the impact of foreign direct investment on domestic economies remains ambiguous. Positive technology spillovers of foreign investment may be outweighed by negative crowding out effect due to increased competition. In this paper, we employ a unique country/sector-level data set to investigate the impact of what is considered the ‘best’ type of foreign ...

The impact of habitual entrepreneurial experience on new firm closure outcomes

In this paper, we argue that it is difficult for habitual entrepreneurs to use their experiential knowledge to develop a more viable new firm than novice entrepreneurs. Hindered by the difficulty of disentangling how actions lead to outcomes in low predictive environments such as new firm settings; hampered by the novelty and uncertainty of new firm closure; and misguided by ...

Genome-Guided Analysis and Whole Transcriptome Profiling of the Mesophilic Syntrophic Acetate Oxidising Bacterium Syntrophaceticus schinkii

Syntrophaceticus schinkii is a mesophilic, anaerobic bacterium capable of oxidising acetate to CO2 and H2 in intimate association with a methanogenic partner, a syntrophic relationship which operates close to the energetic limits of microbial life. Syntrophaceticus schinkii has been identified as a key organism in engineered methane-producing processes relying on syntrophic acetate ...

Complete genome sequence of Methanoculleus bourgensis strain MAB1, the syntrophic partner of mesophilic acetate-oxidising bacteria (SAOB)

Methanoculleus bourgensis strain MAB1 has been identified as the hydrogenotrophic partner of mesophilic acetate-oxidising bacteria, a syntrophic relationship operating close to the thermodynamic equilibrium and of considerable importance in ammonia-rich engineered biogas processes. Methanoculleus bourgensis strain MAB1 belongs to the order Methanomicrobiales, family ...

The microbial community structure in industrial biogas plants influences the degradation rate of straw and cellulose in batch tests

Background Materials rich in lignocellulose, such as straw, are abundant, cheap and highly interesting for biogas production. However, the complex structure of lignocellulose is difficult for microbial cellulolytic enzymes to access, limiting degradation. The rate of degradation depends on the activity of members of the microbial community, but the knowledge of this community in ...

Bacterial community composition and fhs profiles of low- and high-ammonia biogas digesters reveal novel syntrophic acetate-oxidising bacteria

Background Syntrophic acetate oxidation (SAO) is the predominant pathway for methane production in high ammonia anaerobic digestion processes. The bacteria (SAOB) occupying this niche and the metabolic pathway are poorly understood. Phylogenetic diversity and strict cultivation requirements hinder comprehensive research and discovery of novel SAOB. Most SAOB characterised to date ...

Working draft genome sequence of the mesophilic acetate oxidizing bacterium Syntrophaceticus schinkii strain Sp3

Syntrophaceticus schinkii strain Sp3 is a mesophilic syntrophic acetate oxidizing bacterium, belonging to the Clostridia class within the phylum Firmicutes, originally isolated from a mesophilic methanogenic digester. It has been shown to oxidize acetate in co-cultivation with hydrogenotrophic methanogens forming methane. The draft genome shows a total size of 3,196,921 bp, ...

Genome-Guided Analysis of Physiological Capacities of Tepidanaerobacter acetatoxydans Provides Insights into Environmental Adaptations and Syntrophic Acetate Oxidation

This paper describes the genome-based analysis of Tepidanaerobacter acetatoxydans strain Re1, a syntrophic acetate-oxidising bacterium (SAOB). Principal issues such as environmental adaptations, metabolic capacities, and energy conserving systems have been investigated and the potential consequences for syntrophic acetate oxidation discussed. Briefly, in pure culture, T. ...

Biogas production from wheat straw: community structure of cellulose-degrading bacteria

Background Wheat straw is one of the most abundant crop residues produced in the world, making it highly interesting as a substrate for biogas production. However, due to the complex structure, its degradability and gas yield are low. The degradability can be improved by pre-treatment, making the material more accessible to microbial degradation. Methods To investigate the ...

Circadian Modulation of Anxiety: A Role for Somatostatin in the Amygdala

Pharmacological evidence suggests that the neuropeptide somatostatin (SST) exerts anxiolytic action via the amygdala, but findings concerning the putative role of endogenous SST in the regulation of emotional responses are contradictory. We hypothesized that an endogenous regulation of SST expression over the course of the day may determine its function and tested both SST gene ...
