CELL WALLS OF PIRIGULARIA ORYZAE

[摘要] Cell walls were prepared from Piricularia oryzae P2. Lytic enzymes were produced when Bacillus circulans WL 12 was grown with P. oryzae cell wall as a sole source of carbon. Mode of lysis of P. oryzae cell walls was compared with the lysis of walls of Aspergillus oryzae and Neurospora crassa. Activities of β-1→3-glucanase, chitinase, and β-1→6-glucanase were demonstrated in the culture filtrate. Modes of lysis of cell walls of P. oryzae P2 by a single and combined action of lytic enzymes were compared. Combination of β-1→3-glucanase and chitinase gave the most rapid and extensive lysis.
