title: [Screening and fermentation conditions of a bacterial strain over-producing xylanase].
abstract: 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 354 IU/mL in 36 h 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 synthesis. Effects of nitrogen and other factors on enzyme production were also investigated.
