Abstract

This Dissertation / Report is the outcome of investigation carried out by the creator(s) / author(s) at the department/division of Central Food Technological Research Institute (CFTRI), Mysore mentioned below in this page.

Item Type: Student Project Report
Additional Information: The present study was focused on the isolation of the probiotic lactic acid bacteria having bacteriocinogenic properties from okara and further characterization of the isolates. Various physiological tests like growth at various temperature, pH, NaCl concentration and biochemical tests like growth in 0.04 % sodium azide were conducted. From the tests, it was tentatively identified that the isolates might belong to Pediococcus species. Partial characterization of probiotic properties of the selected isolates was examined. Of the main characteristics of a probiotics: acid and bile tolerance, adhesion and autoaggregtion ability, β-galactosidase and β-glucosidase activity, antibiotic susceptibility and production of antimicrobial compound against various pathogens were studied. It was found that the cultures OK2, OK3, OK28 were found to be having appreciable probiotic properties compared to other cultures. Concisely, some strains are considered to be better candidates as probiotics. Unfortunately, none of the strains has all the characteristics of a probiotic. However, the candidates of probiotics can be used as a mixture to get all of the characteristics in one product. It can also be concluded from the study that candidates of probiotic strains do exist in Okara (soy residue). Substantiation can only be possible with accurate taxonomic identification and in vivo studies. The stringent, double-blinded and placebo controlled clinical trials can prove benefits of probiotic strains.
