Lactic acid bacteria (lactic acid bacteria) is a bacterium found naturally and plays an important role in various foods such as milk, soy, fermented sausages, and so on.It also inhibits the growth of microorganisms that cause disease, and foods contaminated with the product. Current lactic acid bacteria and bacteriocin Xin has been interested and studied widely.(Biopreservation), a parody of the treatment groups in the natural balance of microorganisms. So no residue like using chemical
.Isolation of bacteria producing bacteriocin Xin of fish. The bacteriocin Xin is a bacterium that is made from lactic acid bacteria species. And genetic selection nkr-5-3.And inhibitors produced a protein with characteristics of a bacteriocin Xin. Produced by the bacteria e.faecium nkr-5-3-retardant heat. Can inhibit the growth of Gram-positive bacteria tested many kinds. Stable form under conditions that are between 0-24% sodium chloride, pH - bass, 2-10, as well as activity in the inhibition. enterrococcusatcc 19433, which is susceptible to being destroyed by bacteriocin synthesizer such as bactericidal.
