Understanding and modeling the depolymerization mechanisms of cellulosic and lignocellulosic substrates by cellulase cocktails is a critical step towards further optimizing the production of monosaccharides from biomass. The Spezyme CP cellulase cocktail combined with the Novo 188 b-glucosidase...

In an effort developing more efficient and environmentally benign lignocellulosic biomass processing technologies, the authors’ laboratory has been studying plant cell wall degradation process in termite and white-rot fungi. This presentation summarizes the results so far obtained from various...

The current vision of biomass (e.g. plant, algae) conversion technologies is focused on developing the reactive intermediates platform for biofuels and chemicals production. A key challenge in using biomass as a renewable resource is its incredibly diverse polymeric structure. Sugars, furfural, HMF...

Pyrolysis Vapors Upgrading using Metal Oxides Ayman M. Karim 1 , Donghai Mei 1 , Vanessa Lebarbier 1 , Changjun Liu 1,2 and Yong Wang 1,2 1 Pacific Northwest National Laboratory 2 Washington State University The vapors generated during fast pyrolysis of biomass contain a significant fraction of...

The biological pretreatment of wood biomass for degrading lignin, a complex aromatic polymer, has received much attention as an environmentally safe or “green” process. Generally, enzymes isolated from naturally occurring fungi, or with enzymes produced by genetically engineered fungi have been...

Economic biochemical conversion of cellulose to sugars necessitates minimal addition of water to biomass slurries during conversion, resulting in high-solids systems. The resulting slurries are effectively wet-granular materials. These materials presents difficulties for reactor engineering, as...

Catalytic study on lignin degradation and conversion into biofuels Wei Mu and Yulin Deng School of Chemical and Biomolecular Engineering and IPST at GT, Georgia Institute of Technology, Atlanta, Georgia 30332-0620 Author for correspondence (e-mail: yulin.deng@chbe.gatech.edu ) As an ideal...

Plant lignin is a source of useful chemicals, and also the major barrier for saccharification of lignocellulosic biomass for ethanol conversion. The enzymatic lignin degradation/modification could bypass the need for chemical pretreatment and thereby facilitate bioprocess consolidation. Herein, we...

There are two major problems in current cellulosic ethanol production process: low ethanol productivity and high enzyme loading. Based on the current Separate Hydrolysis and Fermentation (SHF) process, it takes at least 96h to perform enzymatic hydrolysis to convert AFEX-CS to fermentable sugars at...
