摘要: 从吉林林蛙(Rana Temporaria)干皮中经CM-52和RP-HPLC两步纯化得到抗菌肽FSE-31.5,利用液体比浊法测定了该抗菌肽对铜绿色假单孢菌的抗菌活力,并利用管碟法进行了抗菌谱研究。本文研究了抗菌肽FSE-31.5对以香肠为代表的肉制食品的防腐作用,和以草莓为代表的瓜果蔬菜的保鲜防腐作用,并对利用抗菌肽代替目前食品中化学防腐剂的可能性进行了探索性研究。

Abstract: We have got one antimicrobial peptide from dried skin of Rana Temporaria by means of CM-52 and RP-HPLCtwo steps purification and assayed the antimicrobial activity of FSE-31.5 by liquid culture method and the antimicrobialspectrum. Then the antisepsis of FSE-31.5 on sausage and the function of keeping fresh of strawberry were studied. Thepossibility of using FSE-31.5 to take the place of chemical preservative is also discussed.
