Recent Progress in Bioconversion of Lignocellulosics

This volume describes recent advances in the bioconversion of lignocellulosics. It starts with two articles on genetics and properties of cellulases and their re- tion kinetics and mechanisms. The cost of cellulases has been a hindrance to large scale use of enzymatic hydrolysis. Two articles on cellulase production by submerged fermentation and by solid state fementation are included to describe the state of the art in this area. Dilute acid hydrolysis of cellulose continues to be of interest as well as potentially useful. The most recent advances in this area is also covered. A great deal of progress has been made in genetic engineering for improved regulation of xylose fermentation by yeasts. An article on genetically engineered Saccharomyces for simulteaneous fermentation of glucose and xylose describes the importance advances made in production of fuel ethanol from lignocellulosic biomass. In recent years, there has been increasing interests in recycling and the reuse of scrap paper as well as environment considerations. A contribution is presented which describes the research perspectives in that area. Finally, recent advances in the use of lignocellulosic biomass for the p- duction of ethanol and organic acids are presented in two articles. Renewable resources are inevitably of great importance in the years to come. There is a never-ending search for better living conditions for human beings. The more resource materials can be recycled, the richer we will be.

This review series covers actual trends in modern biology All aspects of this interdisciplinary technology, where knowledge, methods and expertise are required from chemistry, biochemistry, microbiology, genetics, chemical engineering and computerscience, are treated In parts of the series special volumes are dedicated to selected topics Includes supplementary material: sn.pub/extras

Klappentext

This volume reports the latest advances in the science and technology related to the conversion of lignocellulosics. A portion of the volume is devoted to molecular biology of the enzymes and the microbes involved in the conversion. Hydrolysis of cellulose continues to be of prime importance in the overall conversion scheme. Reaction kinetics and mechanisms of cellulases as well as the state-of-the-art methods of cellulase production by submerged fermentation and also by solid state fermentation are included in the volume. The latest advances made in dilute acid hydrolysis of cellulose are described. Finally, some exciting methods and perspectives for bioconverion of lignocellulosics into ethanol, organic acids and other value-added products are described.This volume should be useful to researchers in this area. It should also be helpful to those who want a concise overview of lignocellulosics.
