摘要：

A newly isolated strain of Bacillus subtilis produced beta-mannanase when cultivated in a medium containing either locust bean gum, konjac mannan or guar gum as a sole carbon source. In contrast, xylanase was produced only when oat spelt xylan or wheat bran was used as a carbon source. The culture supernatant, which contained both beta-mannanase and xylanase, was used to biobleach crude paper pulp to 50% gain in brightness.
