摘要：
A xylanase producer WXULI\|11 was isolated and identified as Pseudomonas sp.By combination treatment of WXULI\|11 with UV and NTG,a mutant WLUN024 was obtained and its enzyme activity reached 354IU/mL in 36h by shaking flask.The mechanism of its xylanase production was primarily studied.The results showed that this enzyme was induced by xylan,xylose and some other xylosic material,while xylose had“two\|way effect”on xylanase synsthesis.Effects of nitrogen and other factors on enzyme production were also investigated.
