from Yasushi Kawai and Tadao Saito writing in Lactic Acid Bacteria and Bifidobacteria: Current Progress in Advanced Research:
Bacteriocins produced by lactobacilli from the lactic acid bacteria (LAB) group have been reported since about 1990 in the same time period when similar bacteriocins were reported in other bacterial species. Almost all of the bacteriocins from lactobacilli belong to class II bacteriocins except for a class III helveticin J produced by Lactobacillus helveticus 481 (37kDa, 333 amino acid residues, using an unknown antibacterial mechanism; Joerger and Klaenhammer, 1990). Interestingly, there have been few reports of class I lantibiotics from lactobacilli. In this chapter, the chemical structure, genetics, mode of action, immunity, and topics concerning lactobacilli bacteriocins are described from the recent decade. Other lactobacilli bacteriocins are referred to from many published papers and reviews.
