摘要
研究了碳源、氮源以及其他因子对木聚糖酶高产菌ＷＬＵＮ０２４（Ｐｓｅｕｄｏｍｏｎａｓ ｓｐ．）产酶的影响，结果表明在麸皮６ｇ／Ｌ、（ＮＨ_４）_２ＳＯ_４ ０．８ｇ／Ｌ、Ｋ_２ＨＰＯ_４ ０．４９／Ｌ、接种量５％～１０％的条件下，３７℃培养３６ｈ，其木聚糖酶活力可达６００ＩＵ／ｍＬ。同时研究了在较优条件下该菌的摇瓶产酶曲线。
Effects of carbon source. nitrogen source and other factors on xylanase production of Pseudomonas sp. WLUN024 were studied. The results showed the optimal conditions for enzyme formation were wheat bran 6%, (NH_4)_2So_4 0.8%, K_2HPO_4 0.4%, inoculum size 5%- 10%. its enzyme activity reached 600IU/mL under 37℃ in 36h. Course of its enzyme production was also investigated.
