Molecular characterization of non-biogenic amines producing Lactobacillus plantarum GP11 isolated from traditional pickles using HRESI-MS analysis.

ABSTRACT: Fungal spoilage and toxic biogenic amine production is a major risk in fermented products. Therefore, the selection of nontoxic biogenic amines producing probiotic bacteria plays a vital role in the fermentation process. In the present study, a total of 18 bacterial isolates were isolated from eight different homemade pickle samples and 15 lactic acid bacteria (LAB) were identified based on biochemical tests. Out of which only seven isolates (GP1, GP2, GP3, GP4, GP5, GP9, and GP11) exhibited antifungal activity against pickle contaminant Aspergillus sp and Penicillium sp. Among the potential LAB isolates, GP11 showed the highest antifungal activity against Aspergillus sp and Penicillium sp with a zone of inhibition 28.33 ± 0.57and 19.66 ± 0.57 mm respectively. T
