Abstract

An aerobic bacterium, designated strain 5N-3 (NBRC 113055), that degrades cis-dichloroethene (cDCE) was isolated from a sea sediment in Japan. Strain 5N-3 was able to degrade a certain amount of cDCE in the presence of pyruvate without the action of inducers. In the presence of inducers, such as phenol and benzene, the strain completely removed cDCE. By the application of 16S ribosomal RNA (16S rRNA) gene sequencing and average nucleotide identity analyses, the strain 5N-3 was identified as Marinobacter salsuginis. On the other hand, identified species of Marinobacter are not known to degrade cDCE at all. A draft genome sequence analysis of the strain 5N-3 suggested that the dmp-homologous operon (operon for phenol degradation) may be contributing to the aerobic degradation of cDCE. This is the first report on an aerobic marine bacterium that has been found to degrade cDCE.
