Nisin CAS 1414-45-5
Nisin ni umuti urwanya bagiteri wa polypeptide ukorwa na Streptococcus lactis, ugizwe na aside amine 34. Iyo yinjiye mu mubiri w'umuntu, irangirika hakoreshejwe enzymes ikajyamo aside amine zitandukanye, nta bisigazwa bisigaramo, nta ngaruka ku miti, kandi nta ngaruka ku binyabuzima biri mu mubiri w'umuntu. Nisin ishobora kubuza neza gukura no kororoka kwa bagiteri nyinshi za Gram-positive zitera kwangirika kw'ibiryo, cyane cyane ko igira ingaruka zikomeye ku kubuza ubushyuhe Bacillus, Clostridium botulinum na Listeria. Nisin ni umuti urinda ibiryo karemano ukora neza cyane, udahumanya, wizewe kandi ugira ingaruka mbi ku biryo, kandi utuma bishonga neza kandi bihoraho.

Nisin (Innis), izwi kandi nka lactobacillus peptide, ni ikintu cya polypeptide gikorwa na Streptococcus lactis. Iyo imaze gukoreshwa, ihita ihinduka aside amine bitewe n’imiterere ya pH y’umubiri w’umuntu n’imikorere ya α -chymotrypsin. Ntihindura imiterere isanzwe y’ibimera mu mara y’umuntu cyangwa ngo itere ibibazo byo kudakora neza nk’izindi antibiyotike. Nisin ntabwo izagira ubudahangarwa hamwe n’izindi antibiyotike kandi ni umuti urinda ibiryo karemano ukora neza cyane, udahumanya, wizewe kandi udasanzwe. Ishobora gukumira no kwica uturemangingo tw’ibimera n’uturemangingo twa bagiteri zitandukanye za Gram-positive nka Bacillus stearophilus, Bacillus cereus, Staphylococcus aureus, Listeria na Clostridium botulinum. Iyo yongewe mu biribwa, ishobora kugabanya cyane ubushyuhe bwo gutobora ibiryo, ikagabanya igihe cyo gutobora, kandi igafasha ibiryo kugumana intungamubiri, uburyohe n’ibara byabyo by’umwimerere.
Nisin ni umuti urwanya udukoko duto cyane ushobora kwica no gukumira bagiteri za Gram gusa kandi ntugira ingaruka ku musemburo, bagiteri za Gram-negative n'ibihumyo. Mu Bushinwa, bivugwa ko ushobora gukoreshwa mu nyama n'ibikomoka ku mata, ku gipimo ntarengwa cya 0.5g/kg. Ikoreshwa ntarengwa mu binyobwa bya poroteyine n'ibigega ni 0.2g/kg.
