Relationship Between Substrate Concentration and Fermentation Product Ratios in Clostridium thermocellum Cultures.

Growth of Clostridium thermocellum in batch cultures was studied over a broad range of cellobiose concentrations. Cultures displayed important differences in their substrate metabolism as determined by the end product yields. Bacterial growth was severely limited when the initial cellobiose concentration was 0.2 (wt/vol), was maximal at substrate concentrations between 0.5 and 2.0%, and did not...

Atypical glycolysis in Clostridium thermocellum.

Cofactor specificities of glycolytic enzymes in Clostridium thermocellum were studied with cellobiose-grown cells from batch cultures. Intracellular glucose was phosphorylated by glucokinase using GTP rather than ATP. Although phosphofructokinase typically uses ATP as a phosphoryl donor, we found only pyrophosphate (PPi)-linked activity. Phosphoglycerate kinase used both GDP and ADP as phosphor...

Electrotransformation of Clostridium thermocellum.

Electrotransformation of several strains of Clostridium thermocellum was achieved using plasmid pIKm1 with selection based on resistance to erythromycin and lincomycin. A custom-built pulse generator was used to apply a square 10-ms pulse to an electrotransformation cuvette consisting of a modified centrifuge tube. Transformation was verified by recovery of the shuttle plasmid pIKm1 from presum...

Cellulose fermentation by Clostridium thermocellum and a mixed consortium in an automated repetitive batch reactor.

An automated repetitive batch fermentation system was developed to facilitate the study of microbial cellulose utilization. The system was operated with Avicel as the carbon source and either Clostridium thermocellum ATCC 27405 or a consortium enriched from compost as inocula. Multiple cycles of growth medium addition, incubation, and medium removal were performed with each inoculum. Removal an...
