Due to global warming and the rise of the CO2 emissions electric mobility is in the focus. In this case costs for li-ion batteries and especially the material costs are the main cost drivers for electric vehicles. The aim of this paper is to develop

Abstract The cultivation of algae either in open raceway ponds or in closed bioreactors could allow the renewable production of biomass for food, pharmaceutical, cosmetic, or chemical industries. Optimal cultivation conditions are however required to

Insertion of metal ions into tetrapyrrole macrocycles is catalyzed by a diverse group of enzymes called chelatases. Structures are known for several chelatases catalyzing metal insertion into protoporphyrin IX or sirohydrochlorin. Despite a lack of s

Comparative analysis of the growing number of microbial genome sequences has shown a high plasticity of genomes and several mechanisms for the adaptation of microbial cells to changing environmental conditions have been discovered. By contrast, the u

We determined key chemical parameters and thiosulfate oxidation in low-temperature hydrothermal fluids from the North Fiji Basin. In addition, the bacterial diversity (with the main emphasis on sulfur-oxidizing bacteria) was investigated. The hydroth

The bacterial diversity of sea ice from Kiel Bight obtained during the rare event of solid ice cover in spring 1996 was analysed by molecular genetic approaches using an improved double gradient denaturing gradient gel electrophoretic method (DG-DGGE

On the basis of available nitrate reductase gene sequences primer pairs were designed to specifically amplify gene stretches of the beta-subunit of the membrane-bound nitrate reductase (narH). Additional sequences of this gene were amplified and sequ
