In this study, a novel betaproteobacterium, strain DPN7T, was isolated under mesophilic conditions from compost because of its capacity to utilize the organic disulfide 3,3′-dithiodipropionic acid. Analysis of the 16S rRNA gene sequence of strain DPN7T revealed 98.5 % similarity to that of Tetrathiobacter kashmirensis LMG 22695T. Values for sequence similarity to members of the genera Alcaligenes, Castellaniella and Taylorella, the nearest neighbours of the genus Tetrathiobacter, were about 95 % or less. The DNA G+C content of strain DPN7T was 55.1 mol%. The level of DNA–DNA hybridization between strain DPN7T and T. kashmirensis LMG 22695T was 41 %, whereas it was much lower between strain DPN7T and Alcaligenes faecalis LMG 1229T (7 %) or Castellaniella defragrans LMG 18538T (5 %). This genotypic divergence was supported by differences in biochemical and chemotaxonomic characteristics. For this reason, and because of the differences in the protein and fatty acid profiles, strain DPN7T should be classified within a novel species of Tetrathiobacter, for which the name Tetrathiobacter mimigardefordensis sp. nov. is proposed. The type strain is strain DPN7T (=DSM 17166T=LMG 22922T).

A Gram-positive, yellowish bacterium strain AK-1Twas isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genusAgromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1Twas closely related toAgromyces aurantiacus(98.6%) followed byAgromyces soli(98.3%),Agromyces tropicus(97.6%),Agromyces ulmi(97.3%),Agromyces flavus(97.2%), andAgromyces italicus(97.0%), whereas the sequence similarity values with respect to the otherAgromycesspecies with validly published names were between 95.3 and 96.7 %. However, the DNA-DNA hybridization values obtained between strain AK-1Tand other related strains were well below the threshold that is required for the proposal of a novel species. The DNAG+Ccontent of the strain is 71.8 mol%. The above data in combination with the phenotypic distinctiveness of AK-1Tclearly indicate that the strain represents a novel species, for which the nameAgromyces arachidissp. nov. is proposed. The type strain is AK-1T(=MTCC 10524T= JCM 19251T).

In 2001, a Gram-variable, facultatively anaerobic, endospore-forming bacterium isolated from biodeteriorated mural paintings in the Servilia tomb of the Roman necropolis of Carmona was deposited as Paenibacillus strain LMG 19508. Subsequently, the strain was characterized in detail using phenotypic and molecular methods. The 16S rRNA gene sequence confirmed that the strain belongs to the genus Paenibacillus and indicated its relationship to Paenibacillus mendelii CCM 4839T (96.7 % sequence similarity). The predominant menaquinone was MK-7. The cell wall contained meso-diaminopimelic acid of the A1γ type. The DNA G+C content (50 mol%) and the major fatty acid (anteiso-C15 : 0) of strain LMG 19508T were also consistent with its affiliation to the genus Paenibacillus. DNA–DNA hybridization distinguished strain LMG 19508T from other phylogenetically related Paenibacillus species. Therefore, the isolate represents a novel species, for which the name Paenibacillus sepulcri sp. nov. is proposed. The type strain is CCM 7311T (=LMG 19508T).

A yellow-pigmented, hexachlorocyclohexane (HCH)-degrading bacterial strain, P25T, was isolated from an HCH dump site located in the northern part of India. Phylogenetic analysis based on the 16S rRNA gene sequence showed that the strain belongs to the genus Sphingobium, as it showed highest sequence similarity to Sphingobium amiense IAM 15006T (97.7 %). The 16S rRNA gene sequence similarity between strain P25T and members of other species of the genus Sphingobium with validly published names ranged from 94.0 to 97.7 %. The DNA–DNA relatedness between strain P25T and Sphingobium amiense IAM 15006T and other related strains was found be less than 30 %, confirming it to represent a novel species. The DNA G+C content of strain P25T was 65 mol%. The polyamine profile showed the presence of spermidine. The predominant cellular fatty acids were summed feature 8 (18 : 1ω7c and/or 18 : 1ω6c; 48.3 %), 16 : 0 (13.7 %) and 14 : 0 2-OH (8.8 %). The polar lipid profile of strain P25T also corresponded to those reported for sphingomonads (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidyldimethylethanolamine, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid), supporting its identification as a member of the family Sphingomonadaceae. The results obtained from DNA–DNA hybridization and biochemical and physiological tests clearly distinguished strain P25T from closely related members of the genus Sphingobium. Thus, a novel species of the genus Sphingobium is proposed, Sphingobium quisquiliarum sp. nov. The type strain is P25T (=MTCC 9472T =CCM 7543T).

Group 1

Two novel species belonging to the genus Shewanella are described on the basis of a polyphasic taxonomic approach. A total of 40 strains of Gram-negative, psychrotolerant, H2S-producing bacteria were isolated from marine fish (cod and plaice) caught in the Baltic Sea off Denmark. Strains belonging to group 1 (seven strains) were a lactate-assimilating variant of Shewanella morhuae with a G+C content of 44 mol%. The strains of group 2 (33 strains) utilized lactate, N-acetylglucosamine and malate but did not produce DNase or ornithine decarboxylase. Their G+C content was 47 mol%. Phylogenetic analysis of the 16S rRNA gene sequence data placed the two novel species within the genus Shewanella. Group 1 showed greatest sequence similarity with S. morhuae ATCC BAA-1205T (99.9 %). However, gyrB gene sequence analysis and DNA–DNA hybridization differentiated these isolates from S. morhuae, with 95.6 % sequence similarity and less than 57 % DNA relatedness, respectively. Group 2 strains shared more than 99 % 16S rRNA gene sequence similarity with the type strains of Shewanella colwelliana and Shewanella affinis, but gyrB sequence similarity (~85 %) and the results of DNA hybridization (~28 %) indicated that the new isolates represented a novel species. Furthermore, when compared to each other, the type strains of S. colwelliana and S. affinis had almost identical gyrB sequences and significantly high DNA reassociation values (76–83 %), indicating that they belonged to the same species. Based on the conclusions of this study, we propose the novel species Shewanella glacialipiscicola sp. nov. (type strain T147T=LMG 23744T=NBRC 102030T) for group 1 strains and Shewanella algidipiscicola sp. nov. (type strain S13T=LMG 23746T=NBRC 102032T) for group 2 strains, and we propose that Shewanella affinis as a later heterotypic synonym of Shewanella colwelliana.
