Evaluation of probiotic properties of Pediococcus acidilactici B14 in association with Lactobacillus acidophilus ATCC 4356 for application in a soy based aerated symbiotic dessert

Abstract

ABSTRACT

Probiotic properties of a phytase producing Pediococcus acidilactici strain SMVDUDB2 isolated from traditional fermented cheese product, Kalarei

“…Intrinsic resistance towards vancomycin is a trait reported in probiotic groups, belonging to Lactobacilli, Pediococci and Leuconostoc genera 29,30 . Resistance against vancomycin and cefotaxime in case of P. acidilactici B14 strain has been reported and vancomycin resistance gene is inherited in Pediococcus genus 13 .…”

“…In present study, P. acidilactici SMVDUDB2 has fulfilled an essential prerequisite ability of probiotic strain to survive in harsh GIT environment with survival rate higher than the literature reports (P. acidilactici B14) survival rate was 45.9% at pH 2.5; 72.4% in 0.3% bile salt concentration and 95.8% after passing through gastrointestinal tract viz. pH 4.0 13 .…”

“…MIC value of the potential probiotic LAB strain was 6% to inhibit the growth of Bacillus subtilis, Mycobacterium smegmatis, Staphylococcus aureus, and Proteus vulgaris while 8% of MIC was observed against Escherichia coli. The importance of organic acids as strong inhibitors against Gram negative bacteria has been reported, whereby the lactic acid acts as permeator of the outer membrane of these bacteria 13,21 .…”

“…Survival rate was determined at low pH (2.0 and 3.0), high bile salt concentration (0.3% and 0.5%) under simulated GIT conditions as per earlier reports 46,47 and a comparative study was carried out with standard probiotic bacterial strain MTCC 1408. Evaluation of pathogenicity factor was carried out by studying the lipolytic effect of the isolate 13 . Table 3.…”

“…Strains of Pediococcus reported for production of bacteriocins include P. acidilactici Kp10 3 and P. acidilactici 12 . P. acidilactici with the capacity for the production of antimicrobial peptide and interesting properties such as resistance to heat, cold, pH and proteolytic treatments have given tremendous importance to the strain 13 . P. acidilactici B14 strain has shown resistance to vancomycin and the gene is considered to be inherent in Pediococcus genus 13 but in some strains P. acidilactici Kp10 3 the strain was found to be susceptible to vancomycin.…”
