In vitro inhibition of Escherichia coli by supernatant of Bacillus coagulans PP01
Original language description
3rd E. coli and Mucosa Immune System, 2.-5.6.2019, Ghent, Belgium. Escherichia coli is a part of the intestinal microflora. Due to the formation of adhesive molecules and toxins, some strains can cause intestinal infections in humans and animals, incl. post-weaning diarrhea in piglets. One of the way how to try to manage the problem is to use probiotic culture which is able to inhibit the growth of Escherichia coli. Aim of the study was to test ability of supernatant of Bacillus coagulans PP01 to inhibit Escherichia coli in vitro. Selected strain of Bacillus coagulans PP01 was positive for enzymatic activity of leucine-, valine- and cystine-arylaminase, naphthol-AS-BI-physphohydrolase, α-glucosidase, β-glucosidase and N-Acetyl-β-glucosaminidase. Ability of supernatant to inhibit growth of E.coli was tested by modification of agar diffuse agar. It was found that the supernatant was able to down-regulate E.coli in a dose-dependent manner. Mean inhibition zone diameter ranged from 0 to 16 from 0.5 to 10 mg of supernatant, respectively. In the experiment, ability of supernatant of Bacillus coagulans PP01 to inhibit Escherichia coli growth in vitro was proven.
