Anaerobic oxidation of ferrous iron by purple bacteria, a new type of phototrophic metabolism.
Anoxic iron-rich sediment samples that had been stored in the light showed development of brown, rusty patches. Subcultures in defined mineral media with ferrous iron (10 mmol/liter, mostlyExpand

Clostridium ljungdahlii represents a microbial production platform based on syngas
Clostridium ljungdahlii is an anaerobic homoacetogen, able to ferment sugars, other organic compounds, or CO2/H2 and synthesis gas (CO/H2). The latter feature makes it an interesting microbe for theExpand

Genome-Wide Gene Expression Analysis of the Switch between Acidogenesis and Solventogenesis in Continuous Cultures of Clostridium acetobutylicum
Clostridium acetobutylicum is able to switch from acidogenic growth to solventogenic growth. We used phosphate-limited continuous cultures that established acidogenic growth at pH 5.8 andExpand

A proteomic and transcriptional view of acidogenic and solventogenic steady-state cells of Clostridium acetobutylicum in a chemostat culture
The complex changes in the life cycle of Clostridium acetobutylicum, a promising biofuel producer, are not well understood. During exponential growth, sugars are fermented to acetate and butyrate,Expand

Transcriptional analysis of catabolite repression in Clostridium acetobutylicum growing on mixtures of D-glucose and D-xylose.
Clostridium acetobutylicum is a strict anaerobic organism that is used for biotechnological butanol fermentation. It ferments various hexoses and pentoses to solvents but prefers glucose presumablyExpand

Characterization of membrane-bound dehydrogenases from Gluconobacter oxydans 621H via whole-cell activity assays using multideletion strains
Gluconobacter oxydans, like all acetic acid bacteria, has several membrane-bound dehydrogenases, which oxidize a multitude of alcohols and polyols in a stereo- and regio-selective manner. ManyExpand
