Regulation of Cellulolytic Activity in Cellulomonas Sp.iibc

چکیده

METHODS The effect of glucose, cellobiose and xylose on the regulation of cellulolytic activity in Cellulomonas sp. ZZbc was investigated. The addition of 1% glucose, cellobiose or xylose to actively growing bagasse pith cultures repressed the cellulose system. No enzyme inactivation by sugar concentrations up to 1.5% was detected. Both cellobiose and xylose, at concentrations ranging from 0.005 to O-0270, served as inducers of the cellulolytic complex in resting cell experiments, while a basal level of constitutive synthesis occurred without any cellulosic substrate or derivative in the culture medium.

The Genome Sequences of Cellulomonas fimi and “Cellvibrio gilvus” Reveal the Cellulolytic Strategies of Two Facultative Anaerobes, Transfer of “Cellvibrio gilvus” to the Genus Cellulomonas, and Proposal of Cellulomonas gilvus sp. nov

Actinobacteria in the genus Cellulomonas are the only known and reported cellulolytic facultative anaerobes. To better understand the cellulolytic strategy employed by these bacteria, we sequenced the genome of the Cellulomonas fimi ATCC 484(T). For comparative purposes, we also sequenced the genome of the aerobic cellulolytic "Cellvibrio gilvus" ATCC 13127(T). An initial analysis of these geno...

49. The Novel Cellulolytic Strategy of Cellulomonas gilvus

Project Goals: The use of cellulolytic bacteria for generating cellulosic ethanol has recently been the focus of extensive research. This research has primarily focused on using engineered strains of cellulolytic bacteria, but there is growing interest in understanding the fundamental processes of cellulose degradation for identifying novel enzymes or for finding organisms capable of more effic...

Draft Genome Sequence of Cellulolytic and Xylanolytic Cellulomonas sp. Strain B6 Isolated from Subtropical Forest Soil

Cellulomonas sp. strain B6 was isolated from a subtropical forest soil sample and presented (hemi)cellulose-degrading activity. We report here its draft genome sequence, with an estimated genome size of 4 Mb, a G+C content of 75.1%, and 3,443 predicted protein-coding sequences, 92 of which are glycosyl hydrolases involved in polysaccharide degradation.

Genomics of Aerobic Cellulose Utilization Systems in Actinobacteria

Cellulose degrading enzymes have important functions in the biotechnology industry, including the production of biofuels from lignocellulosic biomass. Anaerobes including Clostridium species organize cellulases and other glycosyl hydrolases into large complexes known as cellulosomes. In contrast, aerobic actinobacteria utilize systems comprised of independently acting enzymes, often with carboh...

Draft genome sequence of Cellulomonas carbonis T26T and comparative analysis of six Cellulomonas genomes

Most Cellulomonas strains are cellulolytic and this feature may be applied in straw degradation and bioremediation. In this study, Cellulomonas carbonis T26(T), Cellulomonas bogoriensis DSM 16987(T) and Cellulomonas cellasea 20108(T) were sequenced. Here we described the draft genomic information of C. carbonis T26(T) and compared it to the related Cellulomonas genomes. Strain T26(T) has a 3,99...
