This group consists of heat labile proteins which are in general of large molecular weight (>30 kDa).
This group has not been extensively investigated.
Bacteriocins representing this group are helveticin I by
Lactobacillus helveticus and enterolysin produced by Enterococcus faecium [10], [20, 21, 22]. The most
common bacteriocins produced by LAB are summarized in Table 1.0.:
