Transcriptional Regulation of Plant Biomass Degradation and Carbohydrate Utilization Genes in the Extreme Thermophile Caldicellulosiruptor bescii

To develop functional metabolic engineering platforms for nonmodel microorganisms, a comprehensive understanding of the physiological and metabolic characteristics is critical. Caldicellulosiruptor bescii and other species in this genus have untapped potential for conversion of unpretreated plant biomass into industrial fuels and chemicals. The highly interactive and complex machinery used by C. bescii to acquire and process complex carbohydrates contained in lignocellulose was elucidated here to complement related efforts to develop a metabolic engineering platform with this bacterium.

Biological Chemistry of Extreme Thermophile “Caldicellulosiruptor saccharolyticus”- A Future Biofuel Producer

ABSTRACT: The present paper deals with some of those highlighting biochemical capabilities, that lay foundation to exploit the organism ‘caldicellulosiruptor saccharolyticus’emphasizing for finding substitutes for fossil fuels as the organism bears all hallmarks of being adopted as a ‘future biofuel producer’. Belonging to the genus ‘Caldicellulosiruptor’, it is one of the most well studied thermophilic bacterium that possess unique biological chemistry in fermenting substrates very easily with its efficient metabolism.
