Freshwater Reservoir

A novel bacterial strain designated HME7863T was isolated from a freshwater reservoir in Goheung, Republic of Korea. Cells of strain HME7863T were Gram-staining-negative, strictly aerobic, orange-pigmented, rod-shaped and motile by gliding. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain HME7863T formed a lineage within the genus Sediminibacterium . Strain HME7863T was closely related to Sediminibacterium ginsengisoli DCY13T (96.9 % sequence similarity) and Sediminibacterium salmoneum NJ-44T (96.4 %). The major cellular fatty acids were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 0 3-OH and iso-C16 : 0 3-OH. Polar lipid analysis revealed the presence of phosphatidylethanolamine, five unidentified aminolipids, two unidentified aminophospholipids, one unidentified phospholipid and two unidentified polar lipids. The only respiratory quinone was MK-7. The DNA G+C content was 40.5 mol%. On the basis of the evidence presented in this study, strain HME7863T represents a novel species of the genus Sediminibacterium , for which the name Sediminibacterium goheungense sp. nov., is proposed. The type strain is HME7863T ( = KCTC 23945T = CECT 8100T).

Emended Description

A Gram-staining-negative, strictly aerobic, rod-shaped, non-flagellated, non-spore-forming and gliding marine bacterium designated strain CC-AMZ-301T was isolated from coastal surface seawater near Taichung harbour, Taiwan. Strain CC-AMZ-301T predominantly synthesized zeaxanthin and thus formed yellow colonies on marine agar. The novel strain showed high pairwise 16S rRNA gene sequence similarity to Kordia periserrulae IMCC1412T (95.0 %), K. algicida KCTC 8814PT (94.4 %) and K. antarctica IMCC3317T (94.2 %), and formed a phylogenetic lineage tightly associated with species of the genus Kordia . The polar lipid profile of strain CC-AMZ-301T consisted of three unidentified lipids, three unidentified aminolipids and one unidentified phospholipid. The major fatty acids (>5 % of total) were iso-C17 : 0 3-OH, iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0). The DNA G+C content was 36.4 mol%. Menaquinone 6 (MK-6) was the predominant respiratory quinone. The major polyamine was the triamine sym-homospermidine. Based on evidence from the present polyphasic study, strain CC-AMZ-301T is proposed to represent a novel species of the genus Kordia , for which the name Kordia aquimaris sp. nov. is proposed; the type strain is CC-AMZ-301T ( = JCM 18556T = BCRC 80464T). An emended description of the genus Kordia is also proposed.

Heated Soil

A strictly aerobic, thermophilic, moderately acidophilic, non-spore-forming bacterium, strain P373T, was isolated from geothermally heated soil at Waikite, New Zealand. Cells were filamentous rods, 0.2–0.4 µm in diameter and grew in chains up to 80 µm in length. On the basis of 16S rRNA gene sequence similarity, strain P373T was shown to belong to the family Chitinophagaceae (class Sphingobacteriia ) of the phylum Bacteroidetes , with the most closely related cultivated strain, Chitinophaga pinensis UQM 2034T, having 87.6 % sequence similarity. Cells stained Gram-negative, and were catalase- and oxidase-positive. The major fatty acids were i-15 : 0 (10.8 %), i-17 : 0 (24.5 %) and i-17 : 0 3-OH (35.2 %). Primary lipids were phosphatidylethanolamine, two unidentified aminolipids and three other unidentified polar lipids. The presence of sulfonolipids (N-acyl-capnines) was observed in the total lipid extract by mass spectrometry. The G+C content of the genomic DNA was 47.3 mol% and the primary respiratory quinone was MK-7. Strain P373T grew at 35–63 °C with an optimum temperature of 60 °C, and at pH 5.5–8.7 with an optimum growth pH of 7.3–7.4. NaCl tolerance was up to 5 % (w/v) with an optimum of 0.1–0.25 % (w/v). Cell colonies were non-translucent and pigmented vivid yellow–orange. Cells displayed an oxidative chemoheterotrophic metabolism. The distinct phylogenetic position and the phenotypic characteristics separate strain P373T from all other members of the phylum Bacteroidetes and indicate that it represents a novel species in a new genus, for which the name Thermoflavifilum aggregans gen. nov., sp. nov. is proposed. The type strain of the type species is P373T ( = ICMP 20041T = DSM 27268T).

A taxonomic study was carried out on strain SHC163T, which was isolated from the gut of Onchidium reevesii. The bacterium was Gram-stain-negative, oxidase-positive, catalase-negative and rod-shaped. Growth was observed at salinities of 0–4.0 % NaCl and at temperatures of 15–35 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SHC163T belonged to the genus Jannaschia , with the highest sequence similarity to Jannaschia seosinensis CL-SP26T (97.9%), followed by Jannaschia faecimaris DSM 100420T (97.8 %), Jannaschia rubra CECT 5088T (97.5%) and eight species of the genus Jannaschia (94.7−97.1 %). The average amino acid identity, average nucleotide identity and the digital DNA–DNA hybridization estimate values between strain SHC163T and the type strains of the genus Jannaschia were 64.33−79.78 %, 71.0−78.4 % and 19.2−21.0%, respectively. The principal fatty acids (>5 %) were summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c, 56.5 %), C18 : 1  ω7c 11-methyl (23.1 %), C18 : 0 (8.7 %). The G+C content of the chromosomal DNA was 67.8 mol%. The respiratory quinone was determined to be Q-10 (100 %). The polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unidentified phospholipid, an unidentified aminolipid and aminophospholipid. The combined genotypic and phenotypic data show that strain SHC163T represents a novel species within the genus Jannaschia , for which the name Jannaschia marina sp. nov. is proposed, with the type strain SHC163T (=MCCC 1K04032T=KCTC 72524T).
