<P><B>Abstract</B></P><P>Malic acid production from the biodiesel coproduct crude glycerol by<I>Aspergillus</I><I>niger</I>ATCC 9142, ATCC 10577 and ATCC 12846 was observed to occur with the highest malic acid level acid being produced by<I>A. niger</I>ATCC 12846. Fungal biomass production from crude glycerol was similar, but ATCC 10577 produced the highest biomass. Fungal biotransformation of crude glycerol into the commercially valuable organic acid malic acid appeared feasible.</P>
