“…Fatty acid methyl ester analysis of one of the closely related species, Pseudoalteromonas piscicida, showed similar profiles. Our results are in agreement with fatty acid methyl ester profiles for Pseudoalteromonas antarctica (Bozal et al, 1997), P. tunicata (Holmstrom et al, 1998) and seven other type strains of Pseudoalteromonas species (Svetashev et al, 1995). Because of the similar fatty acid composition, fatty acid methyl ester profiles could not differentiate between the Pseudoalteromonas species.…”

A new bacterial species belonging to the genus Pseudoalteromonas is described on the basis of phenotypic characterization, and sequence analysis of its 16S rRNA-coding and gyrase B (gyrB) genes. Ten strains, isolated from sea water of Yamato Island, Sea of Japan, were Gram-negative, yellow, motile, polarly flagellated, aerobic, rod-shaped eubacteria and had a GMC content of 42 mol %. Analysis of the 16S rDNA sequence revealed a clear affiliation between these strains and members of the γ-Proteobacteria. High similarity values were found with members of the genus Pseudoalteromonas and this was supported by fatty acid profiles. The 16S rDNA sequence similarity between strain F12-50-A1 T and Pseudoalteromonas piscicida was very high (99 1 %). However, molecular characterizations employing small subunit 16S rDNA sequences were at the limits of resolution for the differentiation of species in this genus. As a result, DNA-DNA hybridization and sequence analyses of a more rapidly evolving gyrB gene were performed. Our assertion that this strain represents a distinct bacterial species within the genus Pseudoalteromonas was supported by both of these molecular analyses. Species-specific PCR probes were designed for the gyrB gene and used for the rapid screening of F12-50-A1 T -like strains, thereby confirming the species. As these strains cleave complex protein compounds of the Mytilus edulis foot by secreting proteases, the name Pseudoalteromonas peptidolytica sp. nov. is proposed, with strain F12-50-A1 T (l MBICC F1250A1 T ) as the type strain.

“…The marine mussel-thread-degrading strains isolated during this study closely resembled P. luteoviolacea by conventional phenotypic characterization and fatty acid methyl ester profiles (Svetashev et al, 1995). However, these strains were the only pseudoalteromonads showing degradation of marine mussel thread.…”

“…These fatty acid profiles were similar to that of A. macleodii DSM 6062 T (Table 2). A similar fatty acid pattern for the type strain of A. macleodii was reported by Svetashev et al (1995). However, there are differences in the proportion of fatty acids between this study and the study of Svetashev et al (1995), which may be caused by different cultivation, extraction or analytical conditions.…”

Two Gram-negative, motile, non-spore-forming and moderately halophilic rods (strains SW-47 T and SW-49) were isolated from sea water of the East Sea in Korea and subjected to a polyphasic taxonomic study. The two strains grew optimally between 30 and 37 6C, and grew at 4 and 44 6C but not at temperatures above 45 6C. They grew optimally in the presence of 2-5 % (w/v) NaCl, but did not grow in the absence of NaCl. Strains SW-47 T and SW-49 had ubiquinone-8 (Q-8) as the predominant respiratory lipoquinone and C 16 : 1 v7c and/or iso-C 15 : 0 2OH, C 16 : 0 and C 18 : 1 v7c as the major fatty acids, which are consistent with the corresponding data for Alteromonas macleodii. The DNA G+C contents of strains SW-47 T and SW-49 were 45 and 44 mol%, respectively. Strains SW-47 T and SW-49 showed a high level of 16S rDNA sequence similarity (99?9 %) and a mean level of DNA-DNA relatedness of 96?5 %. Phylogenetic analyses based on 16S rDNA sequences showed that the two strains form a coherent cluster with A. macleodii. Strains SW-47 T and SW-49 exhibited levels of 16S rDNA sequence similarity of 99?3 and 99?1 %, respectively, with A. macleodii DSM 6062 T and of less than 89?4 % with other species used in the phylogenetic analyses. Alteromonas fuliginea CIP 105339 T was found to be more closely related to the genus Pseudoalteromonas than to the genus Alteromonas. On the basis of phenotypic properties and phylogenetic and genomic data, strains SW-47 T and SW-49 represent a new species of the genus Alteromonas, for which the name Alteromonas marina (type strain SW-47 T =KCCM 41638 T =JCM 11804 T ) is proposed.

“…Analysis of fatty acid methyl ethers was performed by GLC as described by Svetashev et al (1995). The most relevant cellular fatty acids were saturated, anteiso-and iso-methylbranched acids, namely 12-methyltetradecanoic (15 : 0ai) and 14-methylhexadecanoic (17 : 0ai) fatty acids, which comprised up to 80 % of the total, while 15 : 0i and 16 : 0i were present as minor components (Supplementary Table in IJSEM Online).…”

Two whitish yellow, Gram-positive, non-motile, aerobic bacteria were isolated from enrichment culture during degradation of the thallus of the brown alga Fucus evanescens. The bacteria studied were chemo-organotrophic, mesophilic and grew well on nutrient media containing up to 15 % (w/v) NaCl. The DNA G+C content was 61 mol%. The two isolates exhibited a conspecific DNA-DNA relatedness value of 98 %, indicating that they belong to the same species. A comparative analysis of 16S rRNA gene sequences revealed that strain KMM 3637 T formed a distinct phyletic lineage in the genus Brevibacterium (family Brevibacteriaceae, class Actinobacteria) and showed the highest sequence similarity (about 97 %) to Brevibacterium casei. DNA-DNA hybridization experiments demonstrated 45 % binding with the DNA of B. casei DSM 20657 T . Physiological and chemotaxonomic characteristics (meso-diaminopimelic acid in the peptidoglycan, major cellular fatty acids 15 : 0ai and 17 : 0ai) of the bacteria studied were consistent with the genomic and phylogenetic data. On the basis of the results of this study, a novel species, Brevibacterium celere sp. nov., is proposed. The type strain is KMM 3637 T (=DSM 15453 T =ATCC BAA-809 T ).The genus Brevibacterium was proposed by Breed (1953) for some Gram-positive, non-spore-forming, non-branching rods formerly classified as members of the genus 'Bacterium'. A number of species with diverse morphological, physiological and biochemical properties were subsequently included in the genus (Breed, 1957). The description of the genus was later emended and restricted only to the species that correspond to the type species Brevibacterium linens in terms of morphological and chemotaxonomic characteristics (Collins et al., 1980). Along with B. linens, the following Brevibacterium (sensu stricto) species are currently recognized within the genus:
