Triacylglycerols (TAGs) are in the spotlight as a feasible source of hydrocarbon-based biofuels. Rhodococcus opacus PD630 produces large amounts of intracellular TAGs in cultivations containing high concentrations of glucose, but it does not utilize xylose present in all hydrolysates of lignocellulosic biomass. We constructed a highpotency xylose-fermenting R. opacus strain MITXM-61 that exhibi...

Delignification is the process of breaking lignocellulose into lignin, cellulose, and hemicellulose. The presence lignin in lignocellulosic materials results limited utilization cellulose. This article discusses delignification process. There are various methods from literature study, namely physical, chemical, semi-chemical, mechanical, enzymatic.

BACKGROUND The aromatic compounds cinnamic acid (CA) and p-hydroxycinnamic acid (pHCA) are used as flavoring agents as well as precursors of chemicals. These compounds are present in plants at low concentrations, therefore, complex purification processes are usually required to extract the product. An alternative production method for these aromatic acids is based on the use of microbial strain...

Lignocellulosic biomass, for its large quantities and relatively low cost, is regarded as a potential renewable energy resource for cost-effective ethanol production.1 Wheat straw is one of the most abundant crop residues in European countries with a production of 170 million tonnes per year, and it seems to be one of the cheapest and the most useful raw material for ethanol production.2 Wheat ...

UNLABELLED BACKGROUND Woody biomass is one of the most abundant biomass feedstocks, besides agriculture residuals in the United States. The sustainable harvest residuals and thinnings alone are estimated at about 75 million tons/year. These forest residuals and thinnings could produce the equivalent of 5 billion gallons of lignocellulosic ethanol annually. Softwood biomass is the most recalc...

Lignocellulosic wastes are abundant, renewable and inexpensive sources of energy. This wastes contains large amount of residual plant biomass which is non edible material obtained from plant cell walls. Biomass could be obtained from crop, domestic liquid fuel, municipal solid waste and agricultural residuals. In nature, cellulose, hemicellulose and lignin are major component of plant biomass t...
