摘　　要：通过对不同季度洗衣液生产环境包括空气、设备表面、原材料及生产操作人员等各环节的微生物种属分布特点和优势菌群的分析可知,生产环境中主要微生物类群呈一定趋势分布:空气中主要以球菌、芽孢杆菌属、黄杆菌属和霉菌为主;设备表面和生产操作人员手部以革兰氏阴性菌为主,包括肠杆菌属、假单胞菌属、伯克霍尔德氏菌属、埃希氏菌属和克雷伯氏菌属等,其中第2季度中微生物呈现的种属类别最多;优势菌群属于肠杆菌属、埃希氏菌属、克雷伯氏菌属、假单胞菌属和伯克霍尔德氏菌属等。通过环境样品微生物的采集、优势微生物的筛选,鉴定了对洗衣液产品构成潜在风险的易感微生物菌株。Microbial distribution in liquid laundry detergent manufacturing environment including air, equipment surface, raw materials, operating workers was examined. Results showed that distribution the dominated colonies of microbes in varies place showing a certain trend. Cocci, Bacilli, Flavobacterium and Mold are the dominated colonies in air. Surface of equipment and hands of operating workers are dominated by Gram - negative bacteria, including Enterobacter, Pseudomonas, Burkholderia, Escherichia and Klebsiella et al. In a whole year period, highest number of microbial colonies appears in the second quarter of the year; and Enterobaeter, Escherichia ,Klebsiella, Pseudomonas and Burkholderia are dominated colonies. Via the collection of microbes in environmental samples and screening of the dominated microbial colonies, the susceptible microbial colonies that causing risk of liquid laundry detergent product were identified.
