Chapter IV: Results
presence of α-amylase, DNase and RNase were slightly affected bacteriocin activity (Table
4.22). These results revealed that the antimicrobial substance was of proteinaceous nature and
its activity depended on glycosylation, which required both the glycol portion and the protein
portion for activity.
The detergents used were: sodium dodecyl sulphate (SDS), Tween 80, Tween 20, EDTA and
urea. Sodium dodecyl sulphate (SDS), Tween 80 and Tween 20 could stimulate the
bacteriocin production detergents may be due to non-denaturation of its association with
other molecules, having a stabilizing effect on bacteriocin activity. Bacteriocin showed a
significant decrease (P
