摘要:Kopanisti cheese which is produced from whey curd is a kind of soft and salty fermented dairy product has strong odor with spicy taste and creamy structure. However, its process shows local differences and it is not produced on industrial basis. In this study it is aimed to follow the differences in the numbers of lactic acid bacteria, moulds and yeasts during fermentation and to identify the lactic acid bacteria which play role in fermentation of Kopanisti cheese. Additionally in order to determine the microbial quality of end products microbiological analyses given in Turkish Food Codex were carried out. Samples were taken from the products, at 0, 1, 7, 14, 21, 28 days of fermentation, which produced at a private small local plant in Çeşme and in our laboratory batch. Isolates were named as Lactobacillus brevis , Lactobacillus buchneri , Lactobacillus casei , Lactobacillus collinoides , Lactobacillus johnsonii , Lactococcus lactis subsp . cremoris , Lactobacillus mali , Lactobacillus minor , Lactobacillus oris , Lactobacillus parabuchneri , Lactobacillus reuteri , Lactobacillus sanfrancisco , Lactobacillus sharpeae , Lactobacillus suebicus , Lactobacillus vaginalis and Lactobacillus viridescens on the basis of phenotypic identification.
