[Identification of some thermobacteria isolated from yogurts and the DNA homology of the isolates].

20 thermobacteria were isolated from Turkish yogurts and some cultural characteristics of the isolated were determined. It was found that 5d and 61f resembled Lactobacillus bulgaricus. On the contrary, 8b was entirely different from these two types. In this study, G + C contents of DNA molecules, configuration of lactic acid production, DNA homology, LHD enzymes were determined and result were compared. Types 5d and 61f were found to be important for the dairy industry. Type 8b could not be classified upon its cultural characteristics. The results of DNA homology showed that type 8b was not L. bulgaricus.
