title: [Primary selection method for microorganism producers of organic acids].
abstract: A method is suggested for primary selection of microorganisms producing organic acids. The methods is based on the use of diagnostic media containing the indicator bromocresol green. When yeast fungi of various taxonomic groups were grown in indicator media, 49 yeast cultures producing organic acids were found. Among these, 38 cultures accumulated from 5.0 to 30.0 mg% of citric acid when grown in a medium containing n-paraffins.
