1 Xylan made a profit in the fourth quarter of 1995.

2 The primary studies on the extracellular xylanase of the strain H-1 demonstrated that the xylanase was induced by xylan and cellobiose and inhibited by xylose and glucose.

3 Xylan which is mainly found in plant cell wall is the most abundant regenerate resource secondary to cellulose.

4 When xylan extractives were desalted by ultrafiltration,(www.Sentencedict.com) optimum number of dissolute was 4.

5 Thisindicated that xylan digestion was mainly occurred in the midgut of larvae, especially in the anterior-midgut.

6 With the increase of the xylan contents in broiler diets , the true availabilities of nutrients except P decreased.

7 It was comparatively investigated that xylan was hydrolyzed by crude and purified xylanases in ultrafiltration membrane reactor(UMR) and conventional stirring batch reactor(CSBR).

8 The results observed by SEM showed that xylan existed in the form of xylan-lignin complex in corncob.

9 The char yield for cellulose, xylan and lignin decreases with temperature rise, and finally closes to a constant value about 1.5%, 22% and 26%.

10 The bio-oil from xylan and lignin shows a higher thermal stability.

11 The suitable carbon and nitrogen sources for xylanase production were lactose, mannose, raffinose, xylan, wheat bran , beef extract and yeast extraction.

12 The xylan existing in grain feed is a major kind of anti-nutritional factors, it can reduce feed digestibility significantly and hinder the growth of livestock and poultry.

13 Through the rehydrolysis of filtrate xylan after high temperature pyrogenation, xylo-oligosaccharides increased obviously with the highest proportion of 84.93% in filtrate xylan.

14 The paper reported technology optimization of extracting xylan from corncob by steaming.

15 The changes of the molecular weight distributions of xylan during enzymatic hydrolysis have been investigated with gel filtration chromatography.

16 Based on the study of xylanase, the extracting methods and conditions of xylan from corn cob were improved.

17 The result showed that the DP of xylan decreased 54% after enzymolysis with xylanase, and the content of lowpolymerized xylan was 75.4%.

18 Xylan in nature is a complex of many polysaccharides, and this makes it appears polymorphism and poly-sphere, therefore, it is necessary to classify xylanase of great variety.

19 High quality bamboo vinegar rich in acetic acid, furfural and ethanol, and with little methanol could be obtained from the acid hydrolysis of xylan separated from Alccll pulping liquor.

20 The effect of ultrasonic wave on extraction rate of corn cob xylan was studied.

21 The effects of liquid phase environment on the affinity adsorption of active xylanases from Trichoderma virides to the insoluble oat-spelt xylan and subsequent desorption was investigated.
