Screening of tomato seeds for genetic modification and identification of genetically modified ripening delayed tomato seeds
Türkoğlu, Selda; Gültekin, Güzin Candan; Department of Biotechnology (2007)
Tomato has been genetically modified for providing properties such as insect-resistance or delayed-ripening. Tomato seeds purchased from several bazaars and markets were screened for the presence of genetic modification by targeting NptII kanamycin resistance, Nos terminator, and 35S promoter gene regions which are the most commonly transformed gene regions in transgenic plants, and then ripening-delayed tomato seeds were tried to be identified in this study. F type truncated-PG gene and Sam-k gene were sel...
Screening of biosurfactant producing and diesel oil degrading bacteria from petroleum hydrocarbon contaminated surface waters
Onur, Gözde; İçgen, Bülent; Department of Environmental Engineering (2015)
Hydrocarbon contamination may happen in various ways such as accidents during fuel transportation by trucks and ships, leakage of oil from underground storage tanks, or during extraction and processing of oil. These contaminations can be treated by several methods including physical, chemical and biological treatment. During biological cleaning up, hydrocarbon-degrading bacteria emulsifying hydrocarbons by producing biosurfactants are used. Therefore, isolation and identification of biosurfactant producing ...
Screening of the putative hexokinase genes from rhizopus oryzae
Alagöz, Eda; Hamamcı, Haluk; Yücel, Ayşe Meral; Department of Biotechnology (2013)
Rhizopus oryzae is a filamentous fungus which can ferment sugar to ethanol, and lactic acid. Increasing demand of the world for use of renewable carbon sources has put this and similar organisms into a position where the biotechnology industries are more and more interested with these organisms. R. oryzae can grow on some renewable carbon sources which makes it a good candidate for production of ethanol as well as lactic acid. The major use of lactic acid is in food industry and food- related application, w...

Screening for genetically modified tomatoes & tomato seeds and identification of CRY1AC and SAM-K specific modifications using gene and construct specific PCR
Uçkun, Esra; Gültekin, Güzin Candan; Department of Biotechnology (2007)
This study was carried out to analyze tomato samples and tomato seeds, purchased from different food markets of Turkey randomly, for the presence of genetic modification by using PCR method as it allows more specific detection. The DNAs of collected samples were isolated according to CTAB DNA extraction protocol and also with extraction kits. Screening tests of tomatoes were done by targeting 35S promoter, NOS terminator and NptII kanamycin resistance gene with eight different primer sets. Real time PCR is ...
