The quality of biocrudes from fast pyrolysis lignocellulosic biomass can be improved by optimizing the downstream condensation systems to separate and concentrate selected classes compounds, thus operating different technological solutions temperatures in multiple stages. Scientific literature reports that fractional deployed as an effective relatively affordable step pyrolysis. It consists a c...

Due to the increasing emission of carbon dioxide (CO2), the development of fuels and chemicals based on renewable resources has attracted much attention. Bio-oil, as a carbon rich material, has been considered as a feedstock for biodiesel production. In conventional methanol-mediated transesterification of bio-oil for biodiesel production, significant amounts of glycerol are being generated as ...

Biosynthetic routes based on cost-efficient, eco-friendly, and sustainable platforms for compounds such as styrene are urgently needed. The biosynthesis of from L-phenylalanine (L-Phe) via trans-cinnamate has long been established, but toxicity limits yields. This study demonstrates that whole-cell cascade biotransformation employing an E. coli consortium expressing respectively phenylalanine a...

Bio-based chemicals are seen as a potential stepping-stone towards more sustainable chemical industry. However, while bio-based routes already available for various organic alcohols and acids, the direct production of aromatic compounds has been difficult so far. Recently, first process important aniline realized. The produces via two-stages: first, sugar is fermented by Corynebacterium Glutami...

In view of the worldwide economic and environmental issues associated with the extensive use of petro-chemicals, there has been increasing research interest during the past decade in the value of residual biomass. Because of its renewable nature and abundant availability, residual biomass has attracted considerable attention as an alternate feedstock and potential energy source. To expand the r...

Determining the structural changes of lignin during bio-treatment will facilitate the understanding of biomass recalcitrance during the sustainable production of chemicals and fuels. However, the analysis of milled wood lignin (MWL) cannot completely elucidate the complex and irregular structural changes therein. In this study, MWL and lignin degradation compounds were extracted from white-rot ...

The Manchester Synthetic Biology Research Centre (SYNBIOCHEM) is a foundry for the biosynthesis and sustainable production of fine and speciality chemicals. The Centre's integrated technology platforms provide a unique capability to facilitate predictable engineering of microbial bio-factories for chemicals production. An overview of these capabilities is described.

Given the current robust forces driving sustainable production, and available biomass conversion technologies, biomass-based routes are expected to make a signifi cant impact on the production of bulk chemicals within 10 years, and a huge impact within 20–30 years. In the Port of Rotterdam there is a clear shortterm (0–10 year) substitution potential of 10–15 % of fossil oil-based bulk chemical...

Executive summary: Bacteria biosynthesize secondary metabolites (collaterals) or in other words a large class of biologically active bio compounds, which have applications in agriculture and the pharmaceutical industry. If knowledge’s about bacilli are more advanced (focused on practical applications has enzymes) in the case of actinomycetes the most information has been obtained from studies o...
