摘要
酱菜是我国传统风味的调味佳品,但在酱菜的生产过程中易产生大量的亚硝酸盐,因此从酱菜中分离、筛选出能降解亚硝酸盐的高效菌株尤为重要。本实验利用传统分离纯化方法从酱菜中筛选出的能高效降解亚硝酸盐的菌种,并通过现代分子生物学鉴定方法对其进行分析。结果表明,该筛选出的菌株具有一定的降解亚硝酸盐能力,通过分子生物学鉴定为枯草芽孢杆菌。研究为酱菜生产提供优质菌种资源奠定了一定的基础。
Pickles are a good seasoning with traditional flavors in China,but it is easy to produce a large amount of nitrite in the production process of pickles.Therefore,it is particularly important to isolate and screen high-efficiency strains that can degrade nitrite from pickles.This experiment uses traditional separation and purification methods to screen out strains that can efficiently degrade nitrite from pickles,and analyze them through modern molecular biology identification methods.The results showed that the selected strain has a certain ability to degrade nitrite and was identified as Bacillus subtilis through molecular biology.The research has laid a certain foundation for the provision of high-quality strain resources for the production of pickles.
