Lineage: Fibrobacter succinogenes; Fibrobacter; Fibrobacteraceae; Fibrobacterales; Fibrobacteres; Bacteria

General Information: Temp: Mesophile; Temp: 37C; Habitat: Host. Cellulolytic rumen bacterium. This bacterium is one of the three most predominant cellulolytic organisms in the rumen. Since cellulose is one of the most abundant carbohydrates on the planet, this organism is, therefore, an important part of the global carbon biogeochemical cycle, converting the mass of fixed carbon generated by photosynthetic organisms back to products that eventually end up as carbon dioxide. Increasing cellulose degradation is an important goal in industrial processes. This organism is highly specialized for cellulose degradation, and is only capable of utilizing cellulose and cellulolytic degradation products as carbon sources. Access to cellulose is a rate-liming step in degradation, and the cellulolytic organisms have devised a number of mechanisms for improving access to this insoluble substrate, one of which is the production of surface-localized cellulases. The active enzymes are cell wall associated, but the presence of cellulosomes, large multiprotein cellulase complexes, has not been detected in this organism. Adherence is another method used to promote cellulose degradation, and this organism produces an extracellular matrix of glycoprotein glycocalyx which allows attachment to insoluble cellulose.

Subject: NC_012808:594000 Methylobacterium extorquens AM1, complete genome

Lineage: Methylobacterium extorquens; Methylobacterium; Methylobacteriaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: First isolated in 1960 in Oxford, England, as an airborne contaminant growing on methylamine. This strain can grow on methylamine or methanol, but not methane. This organism is capable of growth on one-carbon compounds such as methanol. Methanol is oxidized to formaldehyde which is then used metabolically to generate either energy or biomass. These bacteria are commonly found in the environment, especially associated with plants which produce methanol when metabolizing pectin during cell wall synthesis. At least 25 genes are required for this complex process of converting methanol to formaldehyde and this specialized metabolic pathway is of great interest.
