单词	nisin
释义	nisin /ˈnʌɪsɪn / noun [mass noun] An antibiotic substance which is a mixture of related polypeptides and is used in some countries as a food preservative. This substance is produced by the bacterium Streptococcus lactis. Thus the intensity of fluorescence is directly proportional to the amount of nisin in the environment.... The authors reported that nisin can be sensitizing via i.p. injection but not by oral treatment. My results suggest that the inactivation of nisin by the producer organism may not be entirely enzymatic. Origin 1940s: from (Group) N i(nhibitory) s(ubstance) + -in1.
