Nisin antimicrobial resistance:
Nisin can inhibit food spoilage caused by many Gram-positive bacteria such as Lactobacillus, Leuconostoc, Pediococcus, Staphylococcus, Listeria monocytogenes, especially on the production of spores of bacteria such as Bacillus, Clostridium has a strong inhibitory effect. Typically, the production of highly heat-resistant bacterial spores, such as milk using 135 ℃, 2 seconds, ultra high temperature sterilization, non-spore bacteria mortality rate was 100%, the mortality rate of 90% of bacterial spores, and 10% The bacteria can not kill the spores. If the milk can be added to 0.03-0.05g/kg Nisin inhibition of Bacillus and Clostridium spores germinate and multiply.
