Nisin CAS 1414-45-5
Nisin chinhu chinorwisa mabhakitiriya chinonzi polypeptide chinogadzirwa neStreptococcus lactis, chine maamino acids 34. Kana yapinda mumuviri wemunhu, inoora nema enzymes kuita maamino acids akasiyana-siyana, isingasiyi zvasara, isingakonzeri kusawirirana nemishonga, uye isingakanganisi ma probiotics mumuviri wemunhu. Nisin inogona kudzivirira kukura nekuberekana kwemabhakitiriya akawanda eGram-positive anokonzera kuora kwechikafu, kunyanya ichidzivirira zvakanyanya Bacillus, Clostridium botulinum naListeria inodzivirira kupisa. Nisin inodzivirira chikafu chechisikigo inoshanda zvikuru, isina chepfu, yakachengeteka uye ine mhedzisiro yakaipa, uye ine kunyunguduka kwakanaka uye kugadzikana.

Nisin (Innis), inozivikanwawo selactobacillus peptide, chinhu chinonzi polypeptide chinogadzirwa neStreptococcus lactis. Mushure mekudyiwa, inokurumidza kunyungudutswa kuita maamino acids pasi pe pH yemuviri wemunhu uye kushanda kweα -chymotrypsin. Haichinje maruva akajairwa mudumbu remunhu kana kukonzera matambudziko ekusagona kudzivirira semamwe maantibiotic. Nisin haizove nekusagona kurwisa mamwe maantibiotic uye inodzivirira chikafu chinoshanda zvikuru, chisina chepfu, chakachengeteka uye chinoshamisa. Inogona kudzivirira nekuuraya masero ezvirimwa nema spores emabhakitiriya akasiyana-siyana eGram-positive akadai seBacillus stearophilus, Bacillus cereus, Staphylococcus aureus, Listeria naClostridium botulinum. Kana ikaiswa muchikafu, inogona kuderedza zvakanyanya tembiricha yekusagona kubvisa utachiona muchikafu, kupfupisa nguva yekusagona kubvisa utachiona, uye kubatsira chikafu kuchengetedza zvinovaka muviri, kuravira uye ruvara rwacho rwepakutanga.
Nisin mushonga unorwisa mabhakitiriya mashoma unogona kungouraya nekudzivirira mabhakitiriya ane Gram-positive chete uye haushande pakurwisa mbiriso, mabhakitiriya ane Gram-negative uye chakuvhuvhu. MuChina, zvinokurudzirwa kuti unogona kushandiswa muzvigadzirwa zvenyama nezvigadzirwa zvemukaka, nekushandiswa kwakanyanya kwe0.5g/kg. Kushandiswa kwakanyanya muzvinwiwa zveprotein yezvirimwa nemakani i0.2g/kg.
