Abstract Alkaliphilic Bacillus sp. strain 41M-1, isolated from soil, produced xylan-degrading enzymes extracellularly. Optimum pH for the crude xylanase preparation was about pH 9, confirming the production of novel alkaline xylanase(s) by the isolate. Xylanases were induced by xylan, but were not produced in the presence of xylose, arabinose or glucose. Xylanase productivity was influenced by culture pH, and production at pH 10.5 was higher than that at pH 8.0. Zymogram analysis of the culture supernatant showed the alkaline xylanase with a molecular mass of 36 kDa.
