what does bacteriocin do
Bacteriocin was first observed by Gratia but the term bacteriocin was coined by Jacob et al. Bacteriocins are antibiotic-like agents produced by some bacteria which are encoded in the plasmids, with the purpose of killing or inhibiting closely related species or even different strains of the same species.lasmid encoding colicin is designated as col. Significance of bacteriocin: Bacteriocins probably have arisen from the need for survival in over-populated environment, thus cells containing the plasmid encoding for a bacteriocin have the capability of destroying surrounding cells.
Bacteriocin production can be induced in a cell by exposure to certain physical and chemical agents. In contrast to bacteriocins produced by gram negative bacteria, its production can not be induced in gram positive bacteria. Bacteriocin typing:Strains can be typed by bacteriocin typing.While phage typing is based on sensitivity of the test strain to the lytic action of standard phages, bacteriocin typing involves ability of the test strain to kill standard indicator strains of bacteria.lasmid encoding colicin is designated as col. Significance of bacteriocin: Bacteriocins probably have arisen from the need for survival in over-populated environment, thus cells containing the plasmid encoding for a bacteriocin have the capability of destroying surrounding cells.
