BACKGROUND The hydrogenosomes of the anaerobic ciliate Nyctotherus ovalis show how mitochondria can evolve into hydrogenosomes because they possess a mitochondrial genome and parts of an electron-transport chain on the one hand, and a hydrogenase on the other hand. The hydrogenase permits direct reoxidation of NADH because it consists of a [FeFe](More)
Classical microbiological methods have nowadays unacceptably long cycle times. Rapid methods, available on the market for decades, are already applied within the clinical and food industry, but the implementation in pharmaceutical industry is hampered by for instance stringent regulations on validation and comparability with classical methods.

Microbial methane oxidizers play a crucial role in the oxidation of methane in marine ecosystems, as such preventing the escape of excessive methane to the atmosphere. Despite the important role of methanotrophs in marine ecosystems, only a limited number of isolates are described, with only four genomes available. Here, we report on two genomes of(More)
Between mid September and the beginning of November 2005, the Animal Health Service (AHS) received thirteen reports offarms on which several animals showed severe symptoms of solar eczema. Blood chemistry showed very high levels of GOT/AST and GGT indicative of severe liver damage. Farm visits to eight farms showed that the animals--previous to the start of(More)
Marine methylotrophs play a key role in the global carbon cycle by metabolizing reduced one-carbon compounds that are found in high concentrations in marine environments. Genome, physiology and diversity studies have been greatly facilitated by the numerous model organisms brought into culture. However, the availability of marine representatives remains(More)
With its capacity for anaerobic methane oxidation and denitrification, the bacterium Methylomirabilis oxyfera plays an important role in natural ecosystems. Its unique physiology can be exploited for more sustainable wastewater treatment technologies. However, operational stability of full-scale bioreactors can experience setbacks due to, for example,(More)
Race cDNA amplification kit (Clontech). Expressed sequence tags were amplified by PCR with the universal adapter primer provided with the kit and the various, specific internal primers. Telomere-specific primers in combination with internal gene sequences allow a straightforward recovery of the complete gene 30. The specific (internal) primers were based on(More)
