摘要
为建立化妆品中日勾维多细菌源菌的检验方法,利用化妆品中常用的SCDLP培养基、双倍乳糖胆盐培养基和伊红美蓝琼脂培养基(EMB)对4株日勾维多细菌源菌进行生长特性研究。结果显示4株日勾维多细菌源菌在SCDLP培养基中均生长良好;3株菌在双倍乳糖胆盐培养基中不生长,添加KH_(2)PO_(4)后,4株菌均正常生长;菌株2507在EMB培养基中生长缓慢,添加酵母浸出粉后,正常生长。表明培养基的pH和营养成分会影响日勾维多细菌源菌的生长,葡萄糖可作为日勾维多细菌源菌选择性培养基的成分之一。
To establish the test method for Pluralibacter gergoviae in cosmetics,the growth characteristics of 4 strains of Pluralibacter gergoviae were studied by using SCDLP medium,double lactose bile salt medium,and eosin-methylene medium(EMB),which are commonly used in cosmetics.Results showed that all four strains of Pluralibacter gergoviae grew well in the SCDLP medium;three strains did not grow in the double lactose bile salt medium,and after adding KH_(2)PO_(4),all four strains grew normally;strain 2507 grew slowly in EMB medium,and after adding yeast extract,it grew normally.It was shown that the pH and nutrient components of the medium would affect the growth of Pluralibacter gergoviae,and glucose could be used as one of the components of the selective medium for Pluralibacter gergoviae.
