Abstract
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.
