Isolation of lactic acid bacteria with probiotic properties

Colostrum is a rich environment for microorganisms. It is particularly rich in probiotic bacteria. For this reason, it was used as a source for isolating lactic acid bacteria. In total, 34 bacteria were obtained. The bacteria were identified according to gram and catalase characteristics. Nine samples were selected and other methods were applied. As a result of molecular studies, the bacteria were identified as Lactacaseibacillus rhamnosus with 99.80% similarity. The amount of lactic acid production was found to be 2.25% and 2.7%. According to the results obtained, nine isolates were resistant to acid and bile salt.
