Cellulose digestion and cellulase regulation and distribution in Fibrobacter succinogenes subsp. succinogenes S85.
Fibrobacter succinogenes subsp. succinogenes S85 initiated growth on microcrystalline cellulose without a lag whether inoculated from a glucose, cellobiose, or cellulose culture. During growth on cellulose, there was no accumulation of soluble carbohydrate. When the growth medium contained either glucose or cellobiose in combination with microcrystalline cellulose, there was a lag in cellulose ...
متن کاملEvaluating Models of Cellulose Degradation by Fibrobacter succinogenes S85
Fibrobacter succinogenes S85 is an anaerobic non-cellulosome utilizing cellulolytic bacterium originally isolated from the cow rumen microbial community. Efforts to elucidate its cellulolytic machinery have resulted in the proposal of numerous models which involve cell-surface attachment via a combination of cellulose-binding fibro-slime proteins and pili, the production of cellulolytic vesicle...
متن کاملEsterase Activities of Fibrobacter succinogenes subsp. succinogenes S85.
Cells of the anaerobic ruminal bacterium Fibrobacter succinogenes subsp. succinogenes S85 (formerly Bacteroides succinogenes) exhibit arylesterase activity. When cells were grown on cellulose, it was found that 69% of the total esterase activity was extracellular while 65% was nonsedimentable upon centrifugation of the culture supernatant at 100,000 x g. Disruption of the cells by various diffe...
متن کاملProduction of maltodextrin 1-phosphate by Fibrobacter succinogenes S85.
We show for the first time the occurrence of maltodextrin-1-Phosphate (MD-1P) (DP2) in F. succinogenes S85, a rumen bacterium specialized in cellulolysis which is not able to use maltose and starch. MD-1P were found in intra and extracellular medium of resting cells incubated with glucose. We used 2D 1H NMR technique and TLC to identify their structure and quantify their production with time. I...
متن کاملFunctional annotation of Fibrobacter succinogenes S85 carbohydrate active enzymes.
Fibrobacter succinogenes is a cellulolytic bacterium that degrades plant cell wall biomass in ruminant animals and is among the most rapidly fibrolytic of all mesophilic bacteria. The complete genome sequence of Fisuc was completed by the DOE Joint Genome Institute in late 2009. Using new expression tools developed at Lucigen and C5-6 Technologies and a multi-substrate screen, 5,760 random shot...
