1株来源于腐败肉制品的沙雷氏菌的分离鉴定与特性研究

Isolation and Characterization of the Serratia sp. ZL01 Derived from Corruption Meat Product

从腐败的肉制品中分离得到1株产耐高温蛋白酶的细菌ZL01,根据其形态学特征、生理生化特性,并结合16S r DNA序列分析结果,发现该菌属于沙雷氏菌属。本研究结果表明,利用Nisin、双乙酸钠、山梨酸钾与Na2EDTA组合防腐剂能显著抑制沙雷氏菌ZL01的繁殖。

A bacterium strain ZL01 producing thermostable protease was isolated from corruption of meat products.The strain was classified into Serratia according to its morphology, physiological-biochemical characteristic and 16 S r DNA sequencing. Also, the mixture of Nisin, sodium diacetate, potassium sorbate, Na2 EDTA could control reproducing of strain ZL01 was shown in the results.
