We studied seven strains of aerobic, marine, polarly flagellated bacteria which decompose alginate, agar, and carrageenan. The major respiratory quinone of these strains was ubiquinone-8. The G+C content of their DNA was 39.5 to 41.7 mol%. “” IAM 12927 and the conspecific five isolates were concluded to constitute a single species distinguished from the other nonpigmented species by DNA-DNA hybridization (homology values of more than 82%) and phenotypic similarity (similarity coefficients, based on assimilation of 145 carbon compounds, were 79 to 96%). “” IAM 12662, the sole extant strain, was distinct from “” and other species in DNA-DNA hybridization and phenotypic features. Taxonomic affinity to was indicated by DNA-DNA hybridization with “” IAM 12927 and the five conspecific isolates (39 to 55%) and with “” IAM 12662 (43 to 45%). Phenotypically, higher similarity values (79 to 89%) for assimilation of 145 carbon compounds were shared between IAM 12927 and the six conspecific strains, including “” IAM 12927. sp. nov. (type strain, IAM 12927, =ATCC 19262, =NCIMB 301) and (type strain, IAM 12662, =IFO 12985, =ATCC 43555, =NCIMB 302) are proposed for “” IAM 12927 and the conspecific five isolates and “” IAM 12662, respectively. A set of phenotypic features which differentiate the two species is described.
