Yeasts, single-celled organisms, are known as intestinal flora of fish and other creatures, however any comprehensive information about them is not available. These unicellular are not only origin of known and unknown diseases; by owing of probiotic properties Such as production of some antibiotics and vitamins are useful for these creatures. According to researches, great population and species diversity of these unicellular yeasts can be anticipated in creature intestine flora. In present study, along with study on species diversity of Saccharomyces genus, as natural intestines flora of Rainbow Trout fishes, several new species similar to Saccharomyces genus were detected in the intestinal flora. Identification of the yeasts flora of rainbow trout fish by molecular techniques of PCR as well as diffraction media could charachterazied not only some strain of Saccharomyces genus but also a new genus of Kazachstania in domestic rainbow trout fishes. Keywords: Saccharomyces, Kazachstania ,Rainbow trout fish, cultute media, Yeast.
