Determination of some significant batch culture conditions affecting acetyl-xylan esterase production by Penicillium notatum NRRL-1249
BACKGROUND Acetyl-xylan esterase (AXE, EC 3.1.1.72) hydrolyses acetate group from the linear chain of xylopyranose residues bound by β-1,4-linkage. The enzyme finds commercial applications in bio-bleaching of wood pulp, treating animal feed to increase digestibility, processing food to increase clarification and converting lignocellulosics to feedstock and fuel. In the present study, we report ...
متن کاملHyperthermostable acetyl xylan esterase
An esterase which is encoded within a Thermotoga maritima chromosomal gene cluster for xylan degradation and utilization was characterized after heterologous expression of the corresponding gene in Escherichia coli and purification of the enzyme. The enzyme, designated AxeA, shares amino acid sequence similarity and its broad substrate specificity with the acetyl xylan esterase from Bacillus pu...
متن کاملCharacterization of crystals of Penicillium purpurogenum acetyl xylan esterase from high-resolution x-ray diffraction.
Acetyl xylan esterase from Penicillium purpurogenum, a single-chain 23 kDa member of a newly characterized family of esterases that cleaves side chain ester linkages in xylan, has been crystallized. The crystals diffract to better than 1 A resolution at the Cornell High Energy Synchrotron Source (CHESS) and are highly stable in the synchrotron radiation. The space group is P2(1)2(1)2(1) and cel...
متن کاملA novel bifunctional acetyl xylan esterase/arabinofuranosidase from Penicillium chrysogenum P33 enhances enzymatic hydrolysis of lignocellulose
BACKGROUND Xylan, the major constituent of hemicellulose, is composed of β-(1,4)-linked xylopyranosyl units that for the backbone, with side chains formed by other chemical moieties such as arabinose, galactose, mannose, ferulic acid and acetyl groups. Acetyl xylan esterases and α-L-arabinofuranosidases are two important accessory enzymes that remove side chain residues from xylan backbones and...
متن کاملProduction of Mycophenolic Acid by Penicillium brevicompactum in a Submerged Batch Culture: Optimization of Culture Conditions Using Taguchi Approach
(Received: Feb. 24, 2013; Accepted in Revised Form: April 9, 2013) Abstract: Mycophenolic acid (MPA) is an antibiotic and immunosuppressive agent, as a secondary metabolite of Penicillium brevicompactum. Parameter optimization of culture composition using Test plan L16, available in the form of an orthogonal array and software for automatic design and analysis of the experiments, both based on ...
