Fermentative production of pyruvic acid by yeasts was studied using extracts from citrus natsudaidai peel as a carbon source. Many yeasts showed good growth. Of these yeasts, Debaryomyces coudertii IFO 1381 produced pyruvic acid at high yield. Pretreatment of the peel extract with Amberlite IR-120B (Na+) led to increased production of pyruvic acid. Under optimum conditions, the accumulation of pyruvic acid reached a maximum of 970mg/100ml at 48hr-fermentation. The pyruvic acid from the fermentation broth was identified with lactic acid dehydrogenase and by comparisons of properties of its 2, 4-dinitrophenylhydrazone with those of authentic pyruvic acid in paper chromatography, IR spectrometry and elemental analysis.
