Multimeric Hemicellulases Facilitate Biomass Conversion

Hemicellulases and auxiliary enzymes for improved conversion of lignocellulosic biomass to monosaccharides

BACKGROUND High enzyme loading is a major economic bottleneck for the commercial processing of pretreated lignocellulosic biomass to produce fermentable sugars. Optimizing the enzyme cocktail for specific types of pretreated biomass allows for a significant reduction in enzyme loading without sacrificing hydrolysis yield. This is especially important for alkaline pretreatments such as Ammonia f...

Reciprocating Biomass Conversion Reactor (RBCR)

The reciprocating biomass conversion reactor (RBCR) is a novel means to produce bio-oil by fast-pyrolysis whose core is a re-purposed 4-cycle internal combustion engine. An inert gas and a small volume-fraction of pulverized biomass are input into the RBCR intake, and the crankshaft is cycled by an external energy source to supply the process heat. The biomass is converted during the compressio...

Novel Thermo-chemical Biomass Conversion with the Reciprocating Biomass Conversion Reactor (rbcr)

Introduction The reciprocating biomass conversion reactor (RBCR) is a novel means of converting biomass to bio-oil. The RBCR is a repurposed highcompression 4-stroke internal combustion engine into which a fluidizing gas and a small volume fraction of pulverized biomass are introduced, and the crankshaft is cycled by an external energy source to supply the process heat for thermo-chemical conve...

Chrysoporthe cubensis: a new source of cellulases and hemicellulases to application in biomass saccharification processes.

The plant pathogenic fungus Chrysoporthe cubensis was cultivated under solid state employing different substrates and the highest endoglucanase (33.84Ug(-1)), FPase (2.52Ug(-1)), β-glucosidase (21.55Ug(-1)) and xylanase (362.38Ug(-1)) activities were obtained using wheat bran as carbon source. Cellulases and xylanase produced by C. cubensis showed maximal hydrolysis rate at pH 4.0 and in a temp...
