Book excerpt: Growing interest in understanding the fundamental processes of bacterial cellulose degradation for the generation of cellulosic ethanol has resulted in the study of the Cellulomonadaceae, a family of cellulolytic bacteria that includes the only reported bacteria capable of degrading and utilizing cellulose both aerobically and anaerobically. This could thus represent a novel strategy for cellulolytic activity, as the most common strategies for aerobic and anaerobic cellulose degradation utilize free or attached cellulases, respectively. These strategies are functionally distinct with any given bacterium employing only one approach. Therefore, bacteria capable of both aerobic and anaerobic cellulose degradation provide a unique opportunity for understanding bacterial strategies for cellulose degradation. This thesis investigates the strategy that cellulomonads use for cellulose degradation by first determining that all 19 species of Cellulomonas tested in this work are capable of degrading cellulose and untreated switchgrass, a more complex lignocellulosic substrate, under both aerobic and anaerobic conditions. Furthermore, these bacteria may be capable of producing ethanol as a byproduct of this metabolism. Investigation into how these bacteria degrade cellulose showed that overall, fewer cellulases were excreted under anaerobic conditions as compared to aerobic conditions, leading to the hypothesis that Cellulomonas switch their cellulolytic strategy in response to oxygen availability. This hypothesis was further examined through a combination of genomic analyses and physiologic assays on Cellulomonas gilvus, a model cellulomonad. Experiments were performed on the motility, chemotactic, cellulase localization, and fiber adherence capabilities of C. gilvus during cellulose degradation, the results of which suggest that C. gilvus degrades cellulose using a novel hybrid of the canonical aerobic and anaerobic strategies and provides further insights into the metabolism of this organism. These insights into the cellulose degradation capabilities of the genus Cellulomonas were then used to help identify and characterize a novel cellulose degrading bacterium isolated by freshmen at the University of Wisconsin-Madison as part of an introductory course. After characterization, this bacterium was named Cellulomonas wisconsinensis as a novel species of the genus Cellulomonas isolated in Wisconsin.

Download or read book Cellulase written by Adam E. Golan and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellulase refers to a class of enzymes produced chiefly by fungi, bacteria, and protozoans that catalyse the cellulolysis (or hydrolysis) of cellulose. The enormous potential that cellulases have in biotechnology is the driving force for continuous basic and applied research on these biocatalysts from fungi and bacteria. Cellulases are found in many fields, such as animal feeding, brewery and wine, food, textile and laundry, pulp and paper products. The growing interest toward the conversion of lignocellulosic biomass into fermentable sugars has generated an additional request for cellulases and their related enzymes. This book presents research in the study of cellulase, including biotechnological applications of microbial cellulases; using agro-industrial by-products as raw material for cellulase production; and the enzyme saccharification of cereal crop residues using dilute alkali pre-treatment.
Download or read book The Prokaryotes written by Edward F. DeLong and published by Springer. This book was released on 2014-10-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea
