Xylanase execute a large variety of function and have many important in biotechnological application. Its application in paper industry, pulp industry, increases the self life of bread, food ndustry. The production of xylanase was investigated in submerged culture of Aspergillus niger. This study was carried out in isolation and screening of xylanase enzyme from the Aspergillus niger fungus. Th...

The xylanase production by a new Cochliobolus sativus Cs5 strain was improved under submerged fermentation. The xylanase was induced by xylan and repressed by glucose, sucrose, maltose, xylose, starch and cellulose. Highest enzyme production (98.25 IU/mL) was recorded when wheat straw (4 % by mass per volume) was used as a carbon source after 120 h of incubation. NaNO3 increased xylanase produc...

The objectives of the present study were isolation, identification, and characterization of xylanase producing actinomycetes, optimization of medium composition and cultural conditions for xylanase production, production using cheaper sources and extraction of extra cellular xylanase from a potential strain. Streptomyces hygroscopicus was selected and optimized for xylanase production in solid ...

The extremely halophilic archaeon Natrinema sp. strain SSBJUP-1, which produces extracellular cellulase and xylanase, was isolated from the Lonar Lake situated in Buldhana, Maharashtra. The enzymes were optimally active at pH 9–10 and temperature 40–60 C and they were most stable up to pH 11 and 16 % of NaCl concentration. The xylanase showed maximum activity at 50C and cellulase at 40C. Xylana...

Cellulases are enzymes used in the hydrolysis of lignocellulosic residues for second-generation (2G) bioethanol production, low availability market, and high-cost impacts 40% total cost 2G production. Therefore, it is necessary to look sustainable alternatives its mainly produced by Aspergillus niger, their activity can be affected nitrogen concentration, use surfactants, carbon source, among o...

Wheat by-products are feedstuffs that vary in nutritional value, partly because of arabinoxylans that limit nutrient digestibility. Millrun is a byproduct from dry milling wheat into flour and contains varying amounts of the bran, middlings, screening, and shorts fractions. The digestible nutrient content of mill-run is not well known. Effects of xylanase supplementation (0 or 4,000 units/kg of...

BACKGROUND In the bioconversion of lignocellulosic substrates, the adsorption behavior of cellulase onto lignin has a negative effect on enzymatic hydrolysis of cellulose, decreasing glucose production during enzymatic hydrolysis, thus decreasing the yield of fermentation and the production of useful products. Understanding the interaction between lignin and cellulase is necessary to optimize t...

Nutrient utilisation and growth performance responses of White Pekin ducks (Anas platyrinchos domesticus) offered diets containing low- or high-viscosity wheat supplemented with xylanase were investigated in two studies. In Expt 1, six diets consisting of low-viscosity wheat or high-viscosity wheat supplemented with 0.0, 1.5 or 3.0 g xylanase (2590 units/g)/kg diet were used in a true metabolis...

The activity of proteins is dictated by their three-dimensional structure, the native state, and is influenced by their ability to remain in or return to the folded native state under physiological conditions. Backbone circularization is thought to increase protein stability by decreasing the conformational entropy in the unfolded state. A positive effect of circularization on stability has bee...
