Reclassification of 'Pseudomonas fluorescens subsp. cellulosa' NCIMB 10462 (Ueda et al. 1952) as Cellvibrio japonicus sp. nov. and revival of Cellvibrio vulgaris sp. nov., nom. rev. and Cellvibrio fulvus sp. nov., nom. rev.
'Pseudomonas fluorescens subsp. cellulosa' NCIMB 10462 has been demonstrated by a polyphasic taxonomic approach to be a member of the genus Cellvibrio. 16S rDNA sequence analysis suggests that this is the only genus that could accept this specimen. The sequence is 95.5% similar to that of Cellvibrio mixtus subsp. mixtus ACM 2601T (the type strain of the type species of the genus), which is its closest relation. The genomic DNA G + C content was determined to be 53.3 mol%, which is similar to the values obtained for the validly described Cellvibrio species. DNA-DNA hybridization experiments have shown that strain NCIMB 10462T (= NCDO 2697T) represents a novel species; therefore, it is proposed that it be designated as the type strain of the novel species Cellvibrio japonicus sp. nov. This study also used 16S rDNA analysis, DNA-DNA hybridization experiments and phenotypic testing to revive the species Cellvibrio vulgaris sp. nov., nom. rev. and Cellvibrio fulvus sp. nov., nom. rev. C. vulgaris NCIMB 8633T (=LMG 2848T) and C. fulvus NCIMB 8634T (=LMG 2847T) are the proposed type strains.
