Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The industrial production of citric acid, an ingredient in beverages, pharmaceuticals, and cosmetics, is based on microbial fermentation of glucose or sucrose. Given the elevated cost of these sugars, lignocellulosic biomass is emerging as a cost‐effective and environmentally friendly feedstock for sustainable bioprocesses.

Cellulase and Chitinase of Earthworms
Nature, 1951 LITTLE is known of the digestive enzymes of the earthworm. The presence of protease, amylase and lipase has been reported in the gut contents in isolated instances. Since up to 10 per cent of the top four inches of soil in grassland may pass through the intestines of worms in a year1, their digestive abilities are of a relevance to transformation of ...

Abscission: Role of Cellulase [PDF]
Plant Physiology, 1969 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

Continuous Cellulase Production [PDF]
Biotechnology and Bioengineering, 1975 AbstractTrichoderma viride QM 9414 growth characteristics on glucose were investigated in single stage continuous stirred tank reactor operation and growth parameters μmax, Ks, QO2 identified. Multistage stirred tank fermentors in series with the first stage utilizing glucose and the subsequent stages utilizing cellulose yielded results in general ...

Evaluation of enzymatic pretreatment strategies to enhance anaerobic digestion of tomato waste
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Tomato residues are a form of solid waste that can be converted into methane through anaerobic digestion (AD). However, methane production is often limited due to incomplete hydrolysis caused by the high lignocellulosic content of tomato waste.

Isolation of Cellulolytic Bacteria and Characterization of the Enzyme
Makara Seri Sains, 2009 Four of cellulolitic bacteria isolates had beencharacterized. The determination of cellulase activity was conducted at the highest production time, using crudeenzymes with the modification of Miller methods (1959) on pure cellulose substrates such as CMC

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study explores the sustainable valorization of fruit waste (FW) for bioethanol production using a consolidated bioprocess (CBP) that combines fermentation and enzymatic hydrolysis in a single step. A co‐culture of Bacillus siamensis F2 (a multienzyme producer) and Candida albicans GP1 (a fermentative yeast) was employed to maximize ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Lignocellulosic biomass is an important source of renewable chemicals and materials but its full valorization is necessary in order to achieve economic and sustainability goals. This study proposes a two‐step approach for the valorization of lignocellulosic biomass combining solvent‐assisted fractionation and catalytic oxidation with molecular

Effect of biopolishing on structural degradation and physical properties of cellulose [PDF]
Journal of the Serbian Chemical Society, 2017 Cellulase treatment on cotton fabric is ecofriendly way of biopolishing. In the present work, biopolishing of cotton fabric using free and immobilized cellulase under various treatment conditions have been carried out using Box-Behnken design and the ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Agroindustrial activity generates substantial waste during harvesting and processing. This study investigated the potential use of sugarcane bagasse, corn cob husk, and wheat bran as substrates for enzyme production by Aspergillus niger and Ceriporiopsis subvermispora. Aspergillus niger and C. subvermispora exhibited comparable filter paperase
