Polygonum orientale (≡ Persicaria orientalis; Polygonaceae), a specie native to a wide region from India to Far East Russia and extending to North and South Australia. For this reason, in here, this taxon is recorded as a new alien species for Turkey. The species was first recorded in Turkey in the Marmara region (Sakarya province, Adapazarı district) in 1936. Subsequently, it...
In this study, it was aimed to investigate the antimicrobial activity and inhibition percentage of citric acid against E. coli, S. aureus and C. albicans as a sanitizer agent. It was researched that persistent/tolerant levels of microorganisms in the citric acid presence. Spectrophotometric Broth Microdilution Method and Surface Disinfection Test were used for antimicrobial...
Sweetgum tree (Liquidambar orientalis Miller) is an endemic tree species grown in Turkey. The tree grown in Muğla region (Köyceğiz, Fethiye) has 4 species in the world. The sweetgum tree is similar in appearance to the plane tree but its leaves are smaller than the sycamore leaf. Trees are long lasting (200-300 years) and have a length of 25-30 meters. The multiplication of the...
This research was done in Düzce during 2018 to study the taxa of naturally distributed Heracleum L., natural habitats of the taxa and floristic composition of the habitats. Results of the field study showed that two different taxa of Heracleum L. including Heracleum platytaenium and Heracleum sphondylium ssp. ternatum were determined in six different habitats such as agriculture...
Horc cheese is a traditional whey product that has been produced by nomads (Yoruks) living in Anatolia for centuries. Recently, it is produced in the villages of Erdemli district of Mersin, albeit rarely. In this study, different producers were reached and the Horc production technique was researched and applied with a manufacturer. In the study, 2.5 kg of Horc was obtained from...
Until now, a considerable number of Miocene conifer trees has been determined using fossil wood identification. Some studies on fossil wood identifications have revealed the need to reconsider certain fossil wood species definitions. The present study aimed to re-analysis the conifer wood identifications (Cupressaceae), which were described as genus, and performed necessary...
