Xylose Metabolism in Bacteria—Opportunities and Challenges towards Efficient Lignocellulosic Biomass-Based Biorefineries

چکیده
In a sustainable society based on circular economy, the use of waste lignocellulosic biomass (LB) as feedstock for biorefineries is promising solution, since LB world’s most abundant renewable and non-edible raw material. available by-product from agricultural forestry processes, its main components are cellulose, hemicellulose, lignin. Following suitable physical, enzymatic, chemical steps, different fractions can be processed and/or converted to value-added products such fuels biochemicals used in several branches industry through implementation biorefinery concept. Upon hydrolysis, carbohydrate-rich fraction may comprise simple sugars (e.g., glucose, xylose, arabinose, mannose) that then fed fermentation units. Unlike pentoses, glucose other hexoses readily by microorganisms. Some wild-type genetically modified bacteria metabolize xylose three pathways metabolism: isomerase pathway, oxidoreductase non-phosphorylative pathway (including Weimberg Dahms pathways). Two commercially interesting intermediates these xylitol xylonic acid, which accumulate medium either manipulation culture conditions or genetic modification bacteria. This paper provides state-of-the art perspective regarding current knowledge transport metabolism well envisaged strategies further increase conversion into valuable products.

Biofuels that are produced from biobased materials are a good alternative to petroleum based fuels. They offer several benefits to society and the environment. Producing second generation biofuels is even more challenging than producing first generation biofuels due the complexity of the biomass and issues related to producing, harvesting, and transporting less dense biomass to centralized bior...

Biomass pretreatment (BP) plays a crucial role in a lignocellulose feedstock-based biorefinery (LCFBR) for processing of three major output streams (cellulose, hemicelluloses and lignin) into chemicals and biofuels. BP includes processing of lignocellulosic material (LCM) under aqueous, dilute acid or alkaline media to obtain a cellulosic fraction, which is then fermented to produce bioethanol....
