3.9.3. Molecular characterization
Proteinaceous nature of bacteriocin from SB93 was confirmed
by its TLC and subsequent staining with ninhydrin. SDS-PAGE
analysis yielded a single band migrating at ~8kD (Fig. 4) which
conformed to the mass characteristic of a Class II bacteriocin (Lu
et al., 2014). This band also inhibited V. cholerae (Fig. 5).
