INTRODUCTION Biorefining is now recognized as a promising solution to transform the pulp and paper (P&P) industry and to generate value-added pathways. The implementation of new products and processes will help companies to diversify revenues, but involves several strategic changes in the business model. Companies will face the dilemma of exiting or not the traditional P&P operations, while sel...

This paper reviews the current refuel valorization facilities as well as the future importance of biorefineries. A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and chemicals from biomass. Biorefineries combine the necessary technologies of the biorenewable raw materials with those of chemical intermediates and final products. Char...

Two-component regulatory systems (TCRSs) mediate cellular response by coupling sensing and regulatory mechanisms. TCRSs are comprised of a histidine kinase (HK), which serves as a sensor, and a response regulator, which regulates expression of the effector gene after being phosphorylated by HK. Using these attributes, bacterial TCRSs can be engineered to design microbial systems for different a...

The world continues to increase its energy use, brought about by an expanding population and a desire for a greater standard of living. This energy use coupled with the realization of the impact of carbon dioxide on the climate, has led us to reanalyze the potential of plant-based biofuels. Of the potential sources of biofuels the most efficient producers of biomass are the photosynthetic micro...

In this study an integrated biorefinery is presented, producing 5-hydroxymethylfurfural (HMF) and products from the hydrothermal liquefaction of spent coffee grounds blended with macroalgae.

Lignocellulose, mostly existing in the form of plant materials, is one of the most abundant organic materials in natural world. It has been estimated that there is an annual worldwide production of 10–50 billion tons of dry lignocellulose, accounting for about half of the global biomass yield . In recent years, due to the escalating energy crisis and environmental pollutions, more extensive att...

BACKGROUND Bio-manufacturing of high-value chemicals in parallel to renewable biofuels has the potential to dramatically improve the overall economic landscape of integrated lignocellulosic biorefineries. However, this will require the generation of carbohydrate streams from lignocellulose in a form suitable for efficient microbial conversion and downstream processing appropriate to the desired...
