Biological formation of methane is the terminal process of biomass degradation in aquatic habitats where oxygen, nitrate, ferric iron and sulphate have been depleted as electron acceptors. The pathway leading from dead biomass to methane through the metabolism of anaerobic bacteria and archaea is well understood for easily degradable biomolecules such as(More)
The taxonomic relationship between several Shewanella putrefaciens isolates from the Baltic Sea and reference strains of this species is presented in this study. Results from DNA-DNA hybridization using a newly developed non-radioactive detection system and from 16S rRNA gene sequencing demonstrated that S. putrefaciens is a heterogeneous species containing(More)
Strain DS-1T is a small (0.8 microm in length and 0.2 microm in diameter) heterotrophic bacterium able to omega-oxygenate the commercial surfactant linear alkylbenzenesulfonate (LAS) and shorten the side chain by beta-oxidation to yield sulfophenylcarboxylates. The morphotype is widespread in cultures able to utilize LAS, and a second organism with similar(More)
During a search for xylan-degrading micro-organisms, a sporulated bacterium was recovered from recent and old cow dung and rectal samples. The isolates were identified as members of a novel species of the genus Paenibacillus, based on 16S rRNA gene sequences. According to the results of phylogenetic analysis, the most closely related species was(More)
Bioremediation is an important technology for the removal of persistent organic pollutants from the environment. Bioaugmentation with the encapsulated Pseudomonas sp. strain MHP41 of agricultural soils contaminated with the herbicide simazine was studied. The experiments were performed in microcosm trials using two soils: soil that had never been previously(More)
