Glycerol Metabolism of the Brown Rot Mould Poria vaillantii


THE characterization of the chemically unchanged lignin of woody tissues requires the removal of the cellulose with which it is associated. The successful utilization of wood-destroying organisms for the isolation of large amounts of enzymically liberated lignin1 and for the elucidation of the mechanism of the biogenesis of lignin building stones2–5 prompted an attempt at the isolation of a cellulolytic enzyme from the wood-destroying mould Poria vaillantii 5. During studies of the cultivation of the mould, an attempt was made to use a medium containing glycerol instead of glucose as the sole carbon source, since glucose interferes in the assay of the cellulolytic enzyme which is obtained from the filtrates.
