Abstract

A novel marine Gram-negative, non-motile, non-spore-forming, aerobic bacterium, associated with the bryozoan , was isolated in a screening programme for strains containing enzymes able to convert the amino acid -serine. Strain MBT-A4 produced -serine dehydratase and was able to grow on -serine as the sole carbon and nitrogen source. The nearest phylogenetic neighbour was , as determined by 16S rDNA sequence analysis (97·6 % similarity). The DNA–DNA reassociation value obtained for DSM11574 and MBT-A4 was 32·6 %. The major ubiquinone was Q-10. Based on genotypic, chemotaxonomic and physiological characteristics, a new species of the genus is proposed, sp. nov., the type strain being strain MBT-A4 (=DSM 14827 =CIP 107400).
