Currently , these scientists are experimenting transferring the gene into yeast , in which they have already produced xylanase 目前，科学家们正在进行实验，将这种基因转移到酵母菌中。
Study on screening of strain used for producing xylanase from beer grains with solid state fermentation and the condition of producing xylanase 固态发酵啤酒糟产木聚糖酶的菌种筛选及其产酶条件研究
Some applications of the enzymes to the pulp bleaching industry were introduced , especially the development of the application of xylanase 摘要介绍了酶在纸浆漂白工业中的研究及应用概况，特别是木聚糖酶在纸浆漂白中的应用及其研究进展。
Its products , which are sold under the rovabio brand , are based primarily on xylanase and betagluconase obtained through the fermentation of penicillium funiculosum 而安迪苏公司是世界第二大蛋氨酸生产商，占有大约百分之三十的市场分额。
The researchers have discovered and copied the shiitake gene , xyn11a , which gives the mushroom the ability to produce the enzyme xylanase , which dissolves wood into sugar 正是xyn11a基因赋予了香菇产生木聚糖酶的能力，而木聚糖酶则可将木材中的复杂有机物如木质素纤维素等分解为葡萄糖和氨基酸。
Had the highest activities of xylanase and cmcase among all isolates . with rice straw as fermentation substrates , the maximum activities of xylanase and cmcase by a4 were 13 . 54 u ? ml - 1 , 0 . 25 u ? ml - 1 , respectively 第二部分对培养基底物及主要组分无细胞瘤胃液和酵母膏对厌氧真菌a4菌产酶的影响进行了研究。
The spores of a . niger m1 , the initial strain , was treated by u . v . at morality of 90 % . a mutant with high xylanase activity was screened , naming a . niger j 506 用紫外线照射的方法对出发菌株aspergillusnigerm1进行处理后，从中筛选到了一株木聚糖酶活力比较高的突变株a . nigerj506 ，传代10次后产酶能力仍然稳定性良好。
Effect of medium components on enzyme production and characterization of anaerobic fungal crude enzymes were also investigated . this thesis was described in the following three sections . in the first section , twelve anaerobic fungal strains isolated from rumen and faeces of ruminants were screened for xylanase and cmcase production 本研究从黑白花种公牛、水牛、山羊粪样及山羊瘤胃内容物中分离到12株厌氧真菌，并对其进行了产高活性羧甲基纤维素酶和木聚糖酶菌株的筛选，同时还就培养基主要组分对厌氧真菌产酶的影响和厌氧真菌的粗酶性质进行了研究。
The reduced level of cell - free rumen fluid had no significant effect on xylanase production , but had significant effect on the cmcase activity . without cell - free rumen fluid , the high concentration level of yeast extract could improve xylanase and cmcase production . in the third section , crude enzymes produced by anaerobic fungus a4 was extracted , and their characteristics of the crude enzyme was also investigated 与基础产酶培养基相比，降低培养基中无细胞瘤胃液浓度对厌氧真菌所产木聚糖酶的酶活及比活力无显著影响( p 0 . 05 ) ，但对其所产的羧甲基纤维素酶的酶活及比活力有显著影响( p 0 . 05 ) 。
According to the published data , three primers had been desighed and synthesized , xyndj - s including siginal sequence and xyna ! - w non - including siginal sequence had been cloned by pcr . according to the determined n - terminal amino acids sequence of xynb and the c - terminal conservative amino acids sequence of g / ll family xylanase Xynbn端十个氨基酸序列与已发表的最高同源性为90 ，根据n端序列测定结果及c端保守序列分别设计了两段引物，经pcr扩增出编码xynb成熟蛋白的核苷酸序列。
