ISOLATION AND IDENTIFICATION OF LACTIC ACID BACTERIA FROM CARP FISH SPECIES IN GUILAN

Background and Aim:solation and identification of lactic acid bacteria from carp species in Guilan province and their probiotic evaluationMethods: In this study, the effectiveness of lactobacilli isolated from different types of carp in Lahijan city in laboratory environment on E.coli and Listeria monocytogenes to select acid and bile acid resistant strains as well as their susceptibility to antibiogram test. Was investigated. In this study, 10 carp samples were used, divided into 3 series, and 6 different lactose bacillus species were obtained from them. The separation of Lactobacillus was done in the MRS environment by purplate method. In this study, two high acidity tolerance and bile salts resistance tests were used to determine the probiotic potential of isolated strainsResults:Probiotics are basically living microbes that are used to treat and prevent certain infectious diseases. So that if it be possible to establish a beneficial organism in the body we can prevent the colonization of various microbial infections.Conclusion:This study, in line with the continuation of research in 1977, has proven that it is better to use probiotics and biotherapy instead of antibiotics to prevent and treat enterotoxigenic infections, which could be a new strategy for biochemical control of E.coli without The use of antibiotics and also helps maintaining the balance of bacterial ecosystems
