Abstract

An aerobic bacterium, strain BN12, which degrades substituted naphthalenesulfonates and substituted salicylates was isolated from a 6-aminonaphthalene-2-sulfonate-degrading microbial consortium originating from the River Elbe, Germany. Chemotaxonomic investigations of quinones, polyamines and polar lipids allowed allocation of this strain to the α-subclass of the and revealed similarity to species of the genera and . This was confirmed by typing with 16S rRNA-targeted oligonucleotide probes and 16S rDNA sequencing and phylogenetic analysis, indicating that BN12clusters most closely with a strain ‘’ THI 051and with the above genera but comprising a separate branch. DNA-DNA hybridizations demonstrated that strain BN12is different from all species of currently described and recognized. The fatty acid patterns, substrate utilization profile and biochemical characteristics displayed no obvious similarity to the characteristics of and species. THI 051, however, revealed phenotypic similarities to BN12. Furthermore, 16S rRNA sequences of showed a high similarity to the 16S rRNA sequences of all currently recognized species. On the basis of these and previously published results, the new genus is proposed, harbouring the two new species sp. nov. and sp. nov. The type strains are BN12(= DSM 6986and THI 051(= IFO 14570), respectively.
