13 Cellulase production in cultures of Acremonium cellulolyticus was significantly 14 improved by using waste milk pack (MP) that had been pretreated with cellulase. When 15 MP cellulose pretreated with cellulase (3 FPU/g MP) for 12 h was used as the sole 16 carbon source for A. cellulolyticus culture in a 3-L fermentor, the cellulase activity was 17 16 FPU/ml. This was 25-fold higher (0.67 FPU...

Background: In the view of depleting resources and ever-increasing price of crude oil, there is an urge for the development of alternative sources to solve the issue of fuel in the coming years. Lignocellulosic biomass is considered to be the most potential alternative resources for fossil fuel. Bioconversion of cellulosic and hemicellulosic components into fermentable sugars is the key step in...

It is possible to improve cellulase production by controlling fungal morphology. Farnesol, the first quorum-sensing molecule found in eukaryotic organisms, is reported to influence the morphology of fungi. In this work, farnesol was investigated for its effect on morphology and cellulase production of Penicillium decumbens. Scanning electron microscopy (SEM) revealed that farnesol promoted the ...

Cellulase induction by beta-glucodisaccharides was investigated by using non-cellulase-induced mycelia of Penicillium purpurogenum P-26, a highly-cellulase-producing fungus. Gentiobiose induced significant amounts of cellulase compared with cellobiose when nojirimycin was added to the induction medium to inhibit extracellular beta-glucosidase activity. Thiogentiobiose (6-S-beta-d-glucopyranosyl...

we introduce some new concepts of topological spaces which say α − separable topologicalspace and o-topological group, α − first axiom, α − second axiom, and we find some relations betweenthem with some applications in normed spaces.

six strain of trichoderma (t. viride, t. harzianum, t. reesei, t. longibrachiatum, t. koningii, t. virens) were isolated and used for extracellular enzyme production. species of trichoderma are collected from the surrounding soil of suger beet root fields in east iran, and held in vitro cultured pda. tcm and tfm are used for the growth of spores and induceing the production of cellulase. finall...

digestibility in broiler chickens fed on corn-soybean meal based diets. the experimental diets consisted of 1.corn-soybean meal based control diet 2. control diet supplemented with pectinas, 3. control diet supplemented with cellulase, 4. control diet supplemented with pectinase + cellulose, 5. control diet supplemented with pectinase + hemicellulase and 6. control diet supplemented with pectin...

Cellulase (beta-1,4-glucan-glucanohydrolase EC 3.2.1.4) activity increased during abscission and was localized in the cell separation layer of Phaseolus vulgaris L. cv. Red Kidney (bean), Gossypium hirsutum L. cv. Acala 4-42 (Cotton) and Coleus blumei Benth. Princeton strain (Coleus) abscission zone explants. Cellulase activity was optimum at pH 7, was reduced by one-half after heating to 55 de...

Cellulase-producing bacteria were isolated from soil and identified as Pseudomonas fluorescens, Bacillus subtilIs, E. coli, and Serratia marcescens. Optimization of the fermentation medium for maximum cellulase production was carried out. The culture conditions like pH, temperature, carbon sources, and nitrogen sources were optimized. The optimum conditions found for cellulase production were 4...
