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.

摘要

真菌分离株 Arthrographis sp. 菌株 F4 在摇瓶培养中，在 30°C、初始 pH 值为 5.0 至 6.0 的条件下，最适产生纤维素酶和木聚糖酶。粗磨滤纸是最适合生产这些酶的碳源。无机氮源比有机氮源产生更高的酶活：NH4NO3 和酵母提取物是最有效的组合。用 0.1%（v/v）吐温 80 可显著刺激（P<0.05）酶的产生。
