A medium was developed for the differential enumeration of homofermentative and heterofermentative lactic acid bacteria. Essential components of the medium included fructose (14 mM), KH(2)PO(4) (18 mM), bromcresol green (as a pH indicator), and other nutrients to support growth. In agar medium, homofermentative colonies were blue to green, while heterofermentative colonies remained white. A total of 21 Lactobacillus, Pediococcus, Leuconostoc, and Streptococcus species were correctly classified with the medium.
研制了一种用于鉴别同型发酵和异型发酵乳酸菌的培养基。培养基的基本成分为果糖（14mM）、KH2PO4（18mM）、溴甲酚绿（作为 pH 指示剂）和其他支持生长的营养物质。在琼脂培养基中，同型发酵菌的菌落呈蓝色到绿色，而异型发酵菌的菌落保持白色。该培养基可正确鉴定 21 种乳杆菌属、肠球菌属、明串珠菌属和链球菌属。
