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 and the existence of ferrous iron-oxidizing anoxygenic phototrophic bacteria may offer an explanation for the deposition of early banded-iron formations in an assumed anoxic biosphere in Archean times.

Clostridium ljungdahlii represents a microbial production platform based on syngas
Clostridium ljungdahlii can be used as a unique microbial production platform based on synthesis gas and carbon dioxide/hydrogen mixtures, and successful expression of these genes could be demonstrated, leading to formation of the biofuel. Expand
Complete genome sequence of the acetic acid bacterium Gluconobacter oxydans
The genome project revealed the unique biochemistry of G. oxydans with respect to the process of incomplete oxidation and revealed many membrane-bound dehydrogenases that are critical for the incomplete oxidation of biotechnologically important substrates. Expand
Ferrous iron oxidation by anoxygenic phototrophic bacteria
NATURAL oxidation of ferrous to ferric iron by bacteria such as Thiobacillus ferrooxidans or Gallionella ferruginea1, or by chemical oxidation2,3 has previously been thought always to involveExpand
The Complete Genome Sequence of Bacillus licheniformis DSM13, an Organism with Great Industrial Potential
From the further analysis of the genome sequence, conserved regulatory DNA motives, the occurrence of the glyoxylate bypass and the presence of anaerobic ribonucleotide reductase explaining that B. licheniformis is able to grow on acetate and 2,3-butanediol as well as anaerobically on glucose.

Modifying the product pattern of Clostridium acetobutylicum
Experimental evidence that butyrate, but not acetate, is re-assimilated via an Adc/CtfAB-independent pathway in C. acetobutylicum is provided, Interestingly, combining the adc and ctfA mutations with a knock-out of the phosphotransacetylase (Pta)-encoding gene, acetate production was drastically reduced, resulting in an increased flux towards butyrates.

Genome-Wide Gene Expression Analysis of the Switch between Acidogenesis and Solventogenesis in Continuous Cultures of Clostridium acetobutylicum
Data indicate that solventogenesis is independent from sporulation, and new insights are led into the physiological role of several genes involved in solvent formation. Expand
A proteomic and transcriptional view of acidogenic and solventogenic steady-state cells of Clostridium acetobutylicum in a chemostat culture
A first systematic study of acidogenic and solventogenic chemostat cultures is presented, and similarities as well as differences to previous studies of batch cultures are discussed. Expand
Transcriptional analysis of catabolite repression in Clostridium acetobutylicum growing on mixtures of D-glucose and D-xylose.
DNA microarrays and real-time RT-PCR were used to study gene expression during growth on D-glucose, D-xylose mixtures on a defined minimal medium together with monitoring substrate consumption and product formation and identified a CRE site in the catabolite repressed operon but not in the operon that was not subject to catabolic repression.

The extracellular proteome of Bacillus licheniformis grown in different media and under different nutrient starvation conditions
The now finished genome sequence of Bacillus licheniformis DSM 13 allows the prediction of the genes involved in protein secretion into the extracellular environment as well as the prediction of theExpand
