High-affinity maltose binding and transport by the thermophilic anaerobe Thermoanaerobacter ethanolicus 39E

Article Abstract:

Thermoanaerobacter ethanolicus 30E has a high-affinity, transport system belonging to the ABC transporter superfamily. It is specific for maltose, maltotriose, and alpha-trehalose.This thermophile produces ethanol from sugars, polymers, and starch.

Carbohydrate transport by the anaerobic thermophile Clostridium thermocellum LQRI

Article Abstract:

There are two separate mechanisms for the cellulose degradation products yielded by the thermophilic bacterium Clostridium thermocellum. Following uptake, cellobiose and cellodextrin are phosphorylated in cytosol, but phosphorylations of cellobiose and cellodextrin are not linked with each other. There is no association between this phosphorylation and the cell membrane. Glucose is taken up by a separate mechanism. Both the uptake mechanisms are ATP dependent.

Clostridium thermocellum JW20 (ATCC 31549) is a coculture with Thermoanaerobacter ethanolicus

Article Abstract:

The contamination of Clostridium thermocellum JW20 (ATCC 31549) with thermoanaebacter ethanolicus was examined. The study used a polymerase chain reaction (PCR) assay based on 16S ribosomal RNA sequence variations of four thermophilic anaerobic bacterial strains. Results suggest the existence of C. thermocellum JW20 (ATCC 31549) as a coculture, gives possible explanation for previous observations of its growth on xylose after weeks of adaptation.
