Abstract
Ramachandran and Walker1 have shown that, in Hida's medium of inorganic salts2, preformed felts of Aspergillus niger produce pyruvic and dimethylpyruvic acids from xylose or from glycerol, and that addition of sodium acetate to the glycerol medium enhances considerably the yield of both these keto-aoids.
