title: Paracoccus seriniphilus sp. nov., an L-serine-dehydratase-producing coccus isolated from the marine bryozoan Bugula plumosa.
abstract: A novel marine Gram-negative, non-motile, non-spore-forming, aerobic bacterium, associated with the bryozoan Bugula plumosa, was isolated in a screening programme for strains containing enzymes able to convert the amino acid L-serine. Strain MBT-A4T produced L-serine dehydratase and was able to grow on L-serine as the sole carbon and nitrogen source. The nearest phylogenetic neighbour was Paracoccus marcusii, as determined by 16S rDNA sequence analysis (97.8% similarity). The DNA-DNA reassociation value obtained for Paracoccus marcusii DSM11574T and MBT-A4T was 32.6%. The major ubiquinone was 0-10. Based on genotypic, chemotaxonomic and physiological characteristics, a new species of the genus Paracoccus is proposed, Paracoccus seriniphilus sp. nov., the type strain being strain MBT-A4T (=DSM 14827T =CIP 107400T).
