Efficient bioalcohol production is a key strategy for sustainable and environmentally friendly practices, especially in utilizing abundant lignocellulosic biomass (LB) derived from agriculture. Agricultural-based LB, which is rich in polysaccharides (cellulose and hemicelluloses) and lignin, presents an opportunity for bioalcohol synthesis in propo...

The solid waste generated through anthropogenic activities like agricultural, food, industrial, medical, and chemical is categorized as municipal solid waste (MSW). Management of this waste via dumping in landfills and uncontrolled burning leads to soil, air, and water pollutions. The improper management of these MSW is unfriendly to the environmen...

Methanol is a potential alternate liquid transportation fuel for blending with gasoline. Biochemical conversion of methane to methanol is a green process for methanol production. This paper reports biochemical methanol production using type I γ‐proteobacteria Methylotuvimicrobium buryatense, which has particular importance from the viewpoint of sca...

Vitamin nano-engineering has been accomplished by synthesizing various nanostructures to improve their stability, bioavailability, shelf life, and functioning. This review provides a detailed description of recent advances in the art of encapsulation with high efficiency through the use of practical and logistic nano-engineering techniques such as...

Sequential extraction of xylan and lignin from alkali pretreated sugarcane tops (apSCT) hydrolysate was carried out. The xylan extracted from apSCT hydrolysate (apSCTx) was 26.5 g and the alkali lignin (apSCTal) was 8.5 g from 100 g of raw SCT. The composition analysis of apSCTx by high performance liquid chromatography showed 74% D-xylose, 15% D-g...

Migration, a critical evolutionary force, can have contrasting effects on adaptation. It can aid as well as impede adaptation. The effects of migration on microbial adaptation have been studied primarily in simple constant environments. Very little is known about the effects of migration on adaptation to complex, fluctuating environments. In our st...

Hemicelluloses are non-soluble plant cell wall polysaccharides that can be separated by alkali or hydrolyzed by dilute acids. Major hemicelluloses are xylan, glucuronoxylan, arabinoxylan, mannan, glucomannan, and galactoglucomannan. The non-toxicity, abundance, and biodegradability of hemicelluloses make it a prospective substrate for the productio...

In present study, the water-soluble extractives removal prior to alkali pretreatment of sugarcane tops (SCT) was carried out. The solid alkali pretreated SCT (apSCT) recovered on Field-emission scanning electron microscopy (FE-SEM) analysis showed exposure of cellulosic fibres as compared with raw SCT. The analyses of apSCT by Fourier Transform Inf...

Sugarcane bagasse (SB) and sugarcane trash (SCT) containing 30% hemicellulose content are the waste from the sugarcane industry. Hemicellulose being heterogeneous, more complex, and less abundant than cellulose remains less explored. The optimized conditions for the pretreatment of SB and SCT for maximizing the delignification are soaking in aqueou...

Xylan is the major hemicellulose present in sugarcane stem secondary cell walls. Xylan is composed of xylose backbone with a high degree of substitutions, which affects its properties. In the present study, the xylan from sugarcane tops (SCT) was extracted and characterized. Compositional analysis of xylan extracted from SCT (SCTx) displayed the pr...

The increasing use of non-renewable resources and its continuous depletion has become a major concern nowadays. The production of renewable fuels from agricultural lignocellulose waste is sustainable and economically feasible. Sugarcane top is one of the most abundant lignocellulosic biomasses in India. More conveniently, it is burned in the field...

Xylan extracted from neem sawdust gave 22.5%, (w/w) yield. The extracted xylan was composed of xylose and glucuronic acid at a molar ratio of 8:1 and with a molecular mass, ~66 kDa. FTIR and NMR analyses indicated a backbone of xylan substituted with 4-O-methyl glucuronic acid at the O-2 position. FESEM analysis showed a highly porous and granular...

Over the past two decades, birchwood and beechwood xylans have been used as a popular substrate for the characterization of xylanases. Recently, major companies have discontinued their commercial production. Therefore, there is a need to find an alternative to these substrates. Xylan extraction from Acacia sawdust resulted in 23.5% (w/w) yield. The...

Lignocellulosic biomass pretreatment is prerequisite to surpass recalcitrance and increase enzymatic accessibility to cellulose for maximum sugar yields. The presence of limited feedstock alternatives, nowadays research has been moved towards exploring various forest and waste feedstock. In the present study Acacia nilotica seeds, Anthocephalus cad...
