摘要:

通过对桃罐头中分离出的微生物进行分离培养、生理生化指标和反证试验进行鉴定和特性研究,初步断定其主要污染菌为凝结芽孢杆菌、黄色丝衣霉、蜡状芽孢杆菌等兼性厌氧菌,并依据实验数据绘制出了三种微生物的生长曲线,建立了一条检验桃罐头中微生物的技术路线。

Abstract:

According to the results of physiological and biochemical tests and microbial counterevidence experiments, microorganisms isolated from deteriorated canned peaches mainly consisted of facultative anaerobic bacteria, including Bysscochlamys ulva, B. coagulans and B. cereus. Based on experimental results, their growth curves were also plotted in this study.

Key words: canned peaches, isolation, identification, characteristics, spoilage bacteria
