乳酸菌中抗李斯特细菌素的筛选及理化性质分析
Screening of anti-Listeria bacteriocin of lactic acid bacteria and its physicochemical characteristics
摘要
Abstract
Strain Y153,isolated from fish balls,produced antimicrobial substance which was inhibitory to Listeria monocytogenes 54003. Strain Y153 was identified as Streptococcus by using 16S rRNA gene sequence homology analysis. After eliminating the effect of organic acid and hydrogen peroxide,the antimicrobial substance with its proteinaceous nature was confirmed as bacteriocin. Bacteriocin Y153 was heat-stable and remained activity after incubation at a wide pH. It could be degraded by proteases existing in the human body. A preliminary study on the bacteriocin producted by Streptococcus strain Y153 had been made to lay the basis for the development of natural food preservative.关键词
