Abstract

Industrial preparation of optically pure D or L lactic acid by fermentation of a nutrient medium which contains a hydrocarbon source, a nitrogen source, phosphoric acid, vitamins and a neutralising agent, with the aid of a microorganism belonging to the Lactobacillus class, characterised in that the nutrient medium additionally contains a fish proteolysate as an additional nitrogen source.
