Extracellular proteases produced by Scytalidium thermophilum, grown on microcrystalline cellulose, were most active at pH 6.5-8 and 37-45 degreesC when incubated for 60 min. Highest protease activity was at day 3 where endoglucanase activity was low. Protease activity measurements with and without the protease inhibitors, p-chloromercuribenzoate, PMSF, antipain, E-64, EDTA and pepstatin A, suggest production of thiol-containing serine protease and serine proteases. Endoglucanase and Avicel-adsorbable endoglucanase activity in culture medium was not significantly affected by protease inhibitors.
