Purification and characterization of two xylanases from alkalophilic and thermophilic Bacillus licheniformis 77-2
(Humana Press Inc, 2006-03-01)
The alkalophilic bacteria Bacillus licheniformis 77-2 produces significant quantities of thermostable cellulase-free xylanases. The crude xylanase was purified to apparent homogeneity by gel filtration (G-75) and ionic ...
Purification and Characterization of Two Extracellular Xylanases from Penicillium sclerotiorum: A Novel Acidophilic Xylanase
(Humana Press Inc, 2010-09-01)
Two xylanases from the crude culture filtrate of Penicillium sclerotiorum were purified to homogeneity by a rapid and efficient procedure, using ion-exchange and molecular exclusion chromatography. Molecular masses estimated ...
Characterization of a cellulase-free xylanase producing Bacillus SP for biobleaching of kraft pulp
(1997-12-01)
Application of the xylanase in the pulp bleaching process has been shown to be effective in decreasing the amount of chlorinating agents in the process and improving the brightness of the pulp, The use of thermostable ...

Xylanase production by Bacillus circulans D1 using maltose as carbon source
(Humana Press Inc, 2008-03-01)
Bacillus circulans D1 is a good producer of extracellular thermostable xylanase. Xylanase production in different carbon sources was evaluated and the enzyme synthesis was induced by various carbon sources. It was found ...
Screening and Production Study of Microbial Xylanase Producers from Brazilian Cerrado
(Humana Press Inc, 2010-05-01)
Hemicelluloses are polysaccharides of low molecular weight containing 100 to 200 glycosidic residues. In plants, the xylans or the hemicelluloses are situated between the lignin and the collection of cellulose fibers ...
Partial purification and properties of cellulase-free alkaline xylanase produced by Rhizopus stolonifer in solid-state fermentation
(Inst Tecnologia Parana, 2005-05-01)
Rhizopus stolonifer was cultivated in wheat bran to produce a cellulase-free alkaline xylanase. The purified enzyme obtained after molecular exclusion chromatography in Sephacryl S-200 HR showed optimum temperature as 45 ...
Use of sugarcane bagasse and grass hydrolysates as carbon sources for xylanase production by Bacillus circulans D1 in submerged fermentation
(Elsevier B.V., 2005-12-01)
The use of sugarcane bagasse and grass as low cost raw material for xylanase production by Bacillus circulans D1 in submerged fermentation was investigated. The microorganism was cultivated in a mineral medium containing ...
