Energy is considered a prime agent in the generation of wealth and a significant factor in economic development. Recently there is renaissance in utilization of biomass for biofuel production employing cellulases and hence forth in obtaining better yields and novel activities. The present study deals with the bioconversion of cellulose from textile cotton waste into ethanol by using the methods...

UNLABELLED BACKGROUND The enzymatic conversion of lignocellulosic plant biomass into fermentable sugars is a crucial step in the sustainable and environmentally friendly production of biofuels. However, a major drawback of enzymes from mesophilic sources is their suboptimal activity under established pretreatment conditions, e.g. high temperatures, extreme pH values and high salt concentrati...

BACKGROUND Previous work has demonstrated that glycerol organosolv pretreatment can effectively improve the hydrolyzability of various lignocellulosic substrates. This pretreatment process strategy is ideal to integrate a commercially successful lignocellulosic and vegetable oil biorefinery industry. However, industrially relevant high-solid-loading hydrolyzability and fermentability of the pre...

Enzymes immobilized on synthetic polyethylene terephthalate (PET) textile surface by resource-efficient inkjet printing technology can promote developments for various novel applications. Synthetic fabrics often require adequate pretreatments to facilitate such process. This work discusses PET–woven fabric pretreatment routes improve wettability alkaline, enzymatic, and plasma processes effecti...

Lignocellulosic biomass, as the largest amount of carbohydrate forms on our planet, has great potential a feedstock for sustainable chemical and material production. However, its conversion is still challenging due to rigid structure complicated composition. It mainly composed cellulose, hemicellulose, lignin. Cellulose linear polymer consisting glucose linked by β-(1,4)glycosidic bonds. Hydrog...

The combination of enzymatic pretreatment cellulose fibers followed by mechanical defibrillation has become a green and low-energy route to obtain nanofibrils (CNF). However, the variability in properties as-produced CNF remains major challenge that needs be addressed for any application realized. Herein, we study effect monocomponent endoglucanase (EG) on energy consumed as well physical obtai...

The tomato processing industry generates large quantities of tomato peel residues, usually creating environmental problems. These residues are a significant source of lycopene, thus providing an attractive alternative for profitable handling of these otherwise problematic by-products. The enzymatic pretreatment of these residues for lycopene recovery has already been employed, although the use ...

An investigation of the effects of ethylene pretreatment on several facets of auxin metabolism in Coleus blumei Benth "Scarlet Rainbow" revealed a number of changes presumably induced by the gas. Transport of indoleacetic acid-1-(14)C in excised segments of the uppermost internode was inhibited by about 50%. Decarboxylation of indoleacetic acid-1-(14)C by enzyme breis was not affected by the pr...
