Diamino Acid

A Gram-positive, non-spore-forming bacterium (GW-12028T) of unknown origin showing filamentous growth and producing spherical sporangia was studied for its taxonomic allocation. The 16S rRNA gene sequence analysis and subsequent similarity studies showed that strain GW-12028T belongs to the genus Streptosporangium , and is most closely related to Streptosporangium pseudovulgare DSM 43181T (99.9 %) and Streptosporangium nondiastaticum DSM 43848T (99.6 %) and more distantly related to Streptosporangium fragile IFO 14311T (98.4 %) and other species of the genus Streptosporangium (95.8 to 98 %). Chemotaxonomic analyses showed that the peptidoglycan diamino acid was meso-diaminopimelic acid. Whole-cell hydrolysates contained madurose as the diagnostic sugar and exhibited a quinone system that contained predominantly menaquinones with nine isoprenoic units in the side chain [MK-9, MK-9(H2), MK-9(H4)]. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phoshatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannosides, four unidentified glycolipids, a phospholipid and an aminolipid. The polyamine pattern contained the major compounds spermine and spermidine. The major fatty acids were 10-methyl C17 : 0, iso-C16 : 0 and C15 : 0. These chemotaxonomic traits are common to other species of the genus Streptosporangium . DNA–DNA hybridizations and physiological and biochemical tests in comparison with the type strains of the most closely related species, S. nondiastaticum and S. pseudovulgare , allowed genotypic and phenotypic differentiation of strain GW-12028T. This strain represents a novel species, for which we propose the name Streptosporangium sandarakinum sp. nov., with the type strain GW-12028T ( = LMG 27062T  = DSM 45763T).

The 16S Rrna Gene

A Gram-stain-positive, rod-shaped, endospore-forming, aerobic bacterium designated SGD-V-25T was isolated from Veraval sediment sample, India. Strain SGD-V-25T was capable of growing at 25–50 °C (optimum 37 °C), pH 6–12 (optimum pH 7.0) and with 0–5 % (w/v) NaCl. The taxonomic position of this strain was deduced using a polyphasic approach and the 16S rRNA gene sequence analysis showed that the isolate belongs to the phylum Firmicutes , forming the cluster with Bacillus badius MTCC 1548T, with which it shares highest similarity of 99.1 % with 13 nt differences. Other type strains of the genus Bacillus showed less than 96 % similarity. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The polar lipid profile of strain SGD-V-25T showed the presence of diphosphatidylglycerol, phosphatidylglycerol, phsophoglycolipid and two aminophospholipids. The predominant isoprenoid quinone was MK-7. The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0, C16 : 1ω11c and C16 : 0. The genomic DNA G+C content of strain SGD-V-25T was 37.6 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA hybridization, strain SGD-V-25T could be clearly distinguished from closely related members of the genus Bacillus , and the name Bacillus encimensis sp. nov., is proposed to accommodate this strain. The type strain is SGD-V-25T ( = NCIM 5513T = DSM 28241T).

Two Gram-stain-positive, non-endospore-forming actinobacteria (Ca8Tand Ca14) were isolated from a bioreactor with extensive phosphorus removal. Based on 16S rRNA gene sequence similarity comparisons, strains Ca8T and Ca14 were shown to belong to the genus Gordonia and were most closely related to Gordonia hirsuta DSM 44140T (98.0 % sequence similarity) and Gordonia hydrophobica DSM 44015T (97.2 %). In comparison with the sequences of the type strains of all other species of the genus Gordonia tested, similarities were below 97 %. The quinone systems of the strains were determined to consist predominantly of MK-9H2. The polar lipid profile for both organisms consisted of diphosphatidylglycerol, phosphatidylglycerol, phospatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. Whole-organism hydrolysates contained meso-diaminopimelic acid as the diamino acid of the peptidoglycan; mycolic acids were detected as well. These chemotaxonomic traits and the major fatty acids, which were C16 : 1 cis-9, C16 : 0 and C18 : 1 and tuberculostearic acid strongly supported the grouping of strains Ca8T and Ca14 into the genus Gordonia . The two strains showed a DNA–DNA similarity of 96 %. DNA–DNA hybridizations of strain Ca8T with G. hirsuta DSM 44140T and G. hydrophobica DSM 44015T resulted in values of 26.3 and 25.0 %, respectively. These results and those of the physiological and biochemical tests allowed a clear phenotypic differentiation of strains Ca8T and Ca14 from the most closely related species of the genus Gordonia . It is concluded that strains Ca8T and Ca14 represent a novel species, for which the name Gordonia phosphorivorans sp. nov. is proposed, with the type strain Ca8T ( = DSM 45630T = CCUG 61533T = CCM 7957T = LMG 26648T).

Strain F2AT, isolated from the cricket Acheta domesticus, was subjected to a polyphasic taxonomic characterization. Cells of the strain were rod-shaped, Gram-stain-negative and catalase- and oxidase-positive. It did not assimilate any carbohydrates. The strain's 16S rRNA gene sequence showed highest similarity to Entomomonas moraniae QZS01T (96.4 %). The next highest similarity values were found to representatives of related genera (<93 %). The genome size of strain F2AT was 3.2 Mbp and the G+C content was 36.4 mol%. Average nucleotide identity values based on blast and MUMmer and average amino acid identity values between strain F2AT and E. moraniae QZS01T were 74.29/74.43, 83.88 and 74.70 %, respectively. The quinone system predominantly contained ubiquinone Q-8. In the polar lipid profile, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified phospholipid were detected. The polyamine pattern consisted of the major compounds putrescine and spermidine. Major fatty acids were C18 : 1 ω7c and C16 : 0 and the hydroxyl acids were C12 : 0 3-OH, C14 : 0 2-OH and C14 : 0 3-OH. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. Due to its association with the only species of the genus Entomomonas but its distinctness from E. moraniae we here propose the novel species Entomomonas asaccharolytica sp. nov. F2AT (=CCM 9136T=LMG 32211T).

A Gram-stain-positive, rod-shaped, endospore-forming, aerobic bacterium capable of growing at 15–42 °C (optimum 30 °C) and at pH 5–11 (optimum pH 7) was isolated from compost. Its taxonomic position was deduced using a polyphasic approach and the strain was designated RC2T. 16S rRNA gene sequence analysis showed that the isolate belongs to the division Firmicutes , forming a clade within the cluster containing Bacillus flexus IFO 15715T, and showed highest similarity to B. flexus IFO 15715T (98.1 %). The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The major cellular fatty acids of the novel strain were iso-C15:0 (36.83 %), anteiso-C15:0 (49.19 %) and C16:0 (5.19 %). DNA–DNA hybridization between strain RC2T and B. flexus DSM 1320T showed a level of relatedness of 54.5 %. The polar lipid profile of strain RC2T showed the presence of phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine. The predominant isoprenoid quinone was MK-7 and the G+C content of strain RC2T was 37.6 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and the results of biochemical and physiological tests, strain RC2T was clearly distinguished from closely related members of the genus, and the strain is assigned to a novel species, for which the name Bacillus paraflexus sp. nov. is proposed. The type strain is RC2T ( = MTCC 9831T = MCC 2100T = KCTC 13724T = CCM 7754T).

A Gram-positive, non-spore-forming actinobacterium (01-Gi-040T) isolated from an indoor wall was studied to examine its taxonomic position. The isolate formed a very rudimentary substrate-mycelium that fragmented into rod-shaped to coccoid cells. On the basis of the 16S rRNA gene sequence similarity studies, strain 01-Gi-040T was shown to belong to the genus Ornithinimicrobium closely related to Ornithinimicrobium kibberense K22-20T (97.1 %), Ornithinimicrobium humiphilum DSM 12362T (96.2 %) and Ornithinimicrobium pekingense LW6T (96.1 %). A close relationship was also found with Arsenicicoccus bolidensis CCUG 47306T (95.9 %) and Arsenicicoccus piscis Kis4-19T (95.7 %) and a moderate relationship to the type strains of the genus Serinicoccus (94.0–94.1 %). The predominant menaquinone of strain 01-Gi-040T was MK-8(H4). The peptidoglycan contained ornithine as the diagnostic diamino acid. The polar lipid profile consisted of the lipids phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol, an unknown phospholipid, an unknown aminolipid and two unknown phosphoglycolipids. The major fatty acids iso-C15 : 0, iso-C16 : 0 and iso-C17 : 0 were consistent with the fatty acid patterns reported for members of the genus Ornithinimicrobium . The results of DNA–DNA hybridizations, physiological and biochemical tests allowed phenotypic differentiation of strain 01-Gi-040T from the three recognized species of the genus Ornithinimicrobium . Strain 01-Gi-040T represents a novel species of the genus Ornithinimicrobium , for which we propose the name Ornithinimicrobium murale sp. nov., with the type strain 01-Gi-040T ( = DSM 22056T = CCM 7610T).

A Gram-stain-positive bacterium, strain RV15T, forming an extensively branched substrate mycelium and aerial hyphae that differentiate into spiral chains of spores, was isolated from a marine sponge Dysidea tupha collected from Rovinj (Croatia). Comparison of 16S rRNA gene sequences showed that strain RV15T is a member of the genus Streptomyces with highest sequence similarity to the type strains of Streptomyces caeruleatus (98.8 %), Streptomyces cyaneochromogenes (98.6 %) and Streptomyces shaanxiensis (98.5 %). Sequence similarities to all other Streptomyces types strains were below 98.5 %. The multilocus sequence analysis-based evolutionary distance, the average nucleotide identity value and the genome-to-genome distance of strain RV15T and the type strain of S. caeruleatus were clearly below the species cut-off values. Strain RV15T exhibited a quinone system composed of the major menaquinones MK-9(H4), MK-9(H6) and MK-9(H2), typical for the genus Streptomyces . The polar lipid profile of strain RV15T consisted of the predominant compounds diphosphatidylglycerol and phosphatidylethanolamine, moderate amounts of phosphatidylinositol, phosphatidylinositol mannoside, an unidentified lipid and an unidentified phospholipid. Major polyamines were spermine and spermidine. The diagnostic diaminoacid of the peptidoglycan was meso-diaminopimelic acid. The major fatty acids were iso C16 : 0, anteiso C17 : 1 ω9c and anteiso C17 : 0. The results of physiological and biochemical tests allowed further phenotypic differentiation of strain RV15T from its most-related species and hence clearly merits species status. We propose the name Streptomyces dysideae sp. nov. with the type strain RV15T (=DSM 42110T=LMG 27702T).
