title: Production of cellulolytic and xylanolytic enzymes by an Arthrographis species.
abstract: A fungal isolate, Arthrographis sp. strain F4, when grown in shake-flask culture, produced cellulolytic and xylanolytic enzymes optimally at 30°C with an initial pH of 5.0 to 6.0. Coarsely-ground filter paper was the most suitable carbon substrate for production of the enzymes. Inorganic nitrogen sources gave higher activities of the enzymes than organic nitrogen sources: NH4NO3 and yeast extract was the most effective combination. Significant stimulation (P<0.05) of enzyme production was achieved with 0.1% (v/v) Tween 80.
