Whole genome sequence analysis and in-vitro probiotic characterization of Bacillus velezensis FCW2 MCC4686 from spontaneously fermented coconut water

• In this study, the probiotic potential of B. velezensis FCW2, isolated from naturally fermented coconut water, was investigated by in vitro and genomic characterization. Our findings highlight key features of the bacterium which includes, antibacterial activity, high adhesive potential, aggregation capacity, production of nutrient secondary metabolites. In vivo safety assessment revealed no adverse effects on zebrafish. WGS data of B. velezensis FCW2 revealed a complete circular genome of 4,147,426 nucleotides and a GC content of 45.87%. We have identified 4059 coding sequence (CDS) genes that encode proteins involved in stress resistance, adhesion and micronutrient production. The genes responsible for producing secondary metabolites, exopolysaccharides, and other beneficial nutrients were identified. The KEGG and COG databases revealed that genes mainly involved amino acid metabolism, carbohydrate utilization, vitamin and cofactor metabolism, and biological adhesion. These findings suggest that B. velezensis FCW2 could be a putative probiotic in the development of fermented foods.
