Immense variations among probiotics for health promoting effects have motivated the research impetus on bioprospecting of new/novel probiotic strains from exotic sources. In the current study, we isolated 20 lactic acid bacterial (LAB) strains from indigenous fermented milk food (kalarei) and evaluated their survival in simulated gastrointestinal juice (GIJ) and functional properties. Six LAB isolates showed high viability (94-99%; log cfu/mL 9.01-11.10). The phenol tolerance assay showed that isolates BK1 and BK2 had high viability of 91.15% and 90.32%, respectively. However, other isolates have shown moderate phenol tolerance (viability 53-82%). The selected LAB isolates were screened for probiotic functional attributes viz. hydrophobicity, autoaggregation and coaggregation. Results revealed that the selected LAB isolates had efficient adhesion ability, autoaggregation and coaggregation ability. Additionally, LAB isolates were investigated for antibiotic susceptibility and antioxidant potential. For ABTS radical scavenging assay, the highest antioxidant activity was shown by isolate BK2 (90.60%), while for DPPH radical scavenging assay, the highest antioxidant activity was shown by BK1 (89.32%). The isolates BK1 and BK2 which have shown promising probiotic functional attributes were identified based on 16S rDNA sequencing as the strains of Lactiplantibacillus plantarum and designated as L. plantarum BK1 OQ927190 and L. plantarum BK2 OQ927187, respectively. |
