During the L-malic acid production in CO_2-fixing fermentation by Schizophyllum commune, a blue coloration of mycelium was seldom seen, and at the same time malate formation was reduced. The earlier the pigment was formed, the more marked decrease of malate production was observed. Addition of lipoic acid, pantothenic acid and thiamine in the medium caused the stimulation of sugar expense and the inhibition of malate formation, as previously reported, but the blue coloration caused the lowering the former and strengthening the latter. Inhibitory effect of Cu^<2+> on malate formation was not affected by blue pigmentation. An addition of ethanolic extract of blue mycelium caused a marked decrease of malate production. From these results, it was supposed that the pigment may promote the reverse reaction of phosphoenolpyruvate carboxylation. The pigment resembled to indigo derivative. When mucilage was produced in the medium, an increase of malate production was observed.
