A new sensitive medium was developed to screen and isolate mutagenic Leuconostoc oenos strains defective in malolactic fermentation. The essential components of the medium included fructose (22 mM), l-malic acid (74.6 mM), bromocresol green (as pH indicator), and cellulose powder. The wild-type colonies turned blue, but defective malolactic colonies gave an acid reaction and remained yellow-green.
一种新的灵敏培养基被开发出来，用于筛选和分离突变性乳球菌（Leuconostoc oenos）菌株，这些菌株在苹果酸-乳酸发酵中存在缺陷。该培养基的基本成分包括果糖（22mM）、L-苹果酸（74.6mM）、溴甲酚绿（作为 pH 指示剂）和纤维素粉。野生型菌落呈蓝色，而缺陷型的苹果酸-乳酸发酵菌落则呈酸性反应，保持黄绿色。
