Different conditions which may have effects on alkaline xylanase production were studied.

The alkali-tolerant xylanase gene of Bacillus pumilus A-30 was cloned by PCR.

Many modifiers were used to react with alkaline xylanase (XynA).

According to RBB-xylan-hydrolyzed halos method , A bacterial strain which can produce extra-cellular alkaline xylanase, was isolated from alkaline soil near the drain ditch of a paper-producing factory .

The gene fragment encoding alkaline xylanase(xylA) was cloned successfully from pCT124 plasmid by PCR method.
