For my PhD research, I characterized some Bacillus subtilis and Bacillus velezensis strains isolated from dairy plant using multi-locus sequencing technique (MLST) to source-track their contamination and mitigate their challenge during processing. Their spores were subjected to UVC in a suspending medium to determine their inactivation parameters. The biofilms and spoilage potential were also determined for the Bacillus subtilis complex group.
