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...

BACKGROUND Consolidated bioprocessing (CBP) of lignocellulosic biomass to hydrogen offers great potential for lower cost and higher efficiency compared to processes featuring dedicated cellulase production. Current studies on CBP-based hydrogen production mainly focus on using the thermophilic cellulolytic bacterium Clostridium thermocellum and the extremely thermophilic cellulolytic bacterium ...

The evolution of cellulose degradation was a defining event in the history of life. Without efficient decomposition and recycling, dead plant biomass would quickly accumulate and become inaccessible to terrestrial food webs and the global carbon cycle. On land, the primary drivers of plant biomass deconstruction are fungi and bacteria in the soil or associated with herbivorous eukaryotes. While...

The purpose of this study was to isolate cellulolytic enzyme producing bacteria which may able to utilize banana pseudostem as sole carbon source for production of cellulolytic enzymes. This was attempted by isolating 10 bacteria from banana pseudostem waste. Out of the screened, isolate NAULH-5 showed high cellulolytic activity. The isolate NAULH-5 produced highest 5.97 U/mg endoglucanase, 2.2...

Carbon metabolism in anaerobic cellulolytic bacteria has been investigated essentially in Clostridium thermocellum, Clostridium cellulolyticum, Fibrobacter succinogenes, Ruminococcus flavefaciens, and Ruminococcus albus. While cellulose depolymerization into soluble sugars by various cellulases is undoubtedly the first step in bacterial metabolisation of cellulose, it is not the only one to con...

Several ruminal cellulolytic bacteria species are sensitive to pH and could therefore be used as biomarkers to determine the risk of sub-acute ruminal acidosis (SARA) in finishing lambs. This study compared a 2-4 h post feeding ruminal pH measurement to abundances of the ruminal pH-sensitive bacteria to evaluate the risk of SARA in a herd of 120 finishing lambs. The lambs were reared in individ...

In order to meet the global nutritional needs of a growing population, attempts are being made develop strategies that can effectively offset negative effects intensive farming. The aim this study was investigate effect Effective Microorganisms (EM) preparation and organic matter incorporation on soil microbiological chemical features. analyses included number heterotrophic bacteria, fungi, act...
