“…Both Mychonastes and Nannochloropsis OTUs were correlated with a group of five bacterial OTUs (G1 group, indicated by shaded area in Figure 6A) which were closely related to three aerobic chemoheterotrophs including Balneola alkaliphila (NR_044367.1, 99% similarity) (Urios et al, 2008), Rathayibacter festucae (NR_042574.1, 99%) (Stackebrandt et al, 2007) and Brumimicrobium mesophilum (NR_115845.1, 95%) (Yang et al, 2013), an aerobic anoxygenic phototroph Roseibacterium beibuensis sp. (NR_132716.1, 97%) (Mao et al, 2012), as well as a likely endosymbiont Olavius algarvensis (AJ620496.1, 96%) (Ruehland et al, 2008). In addition, the Nannochloropsis OTU-AF045049.1.1790 also co-occurred with an OTU in the family Flavobacteriaceae.…”

The McMurdo Dry Valley (MDV) lakes represent unique habitats in the microbial world. Perennial ice covers protect liquid water columns from either significant allochthonous inputs or seasonal mixing, resulting in centuries of stable biogeochemistry. Extreme environmental conditions including low seasonal photosynthetically active radiation (PAR), near freezing temperatures, and oligotrophy have precluded higher trophic levels from the food webs. Despite these limitations, diverse microbial life flourishes in the stratified water columns, including Archaea, bacteria, fungi, protists, and viruses. While a few recent studies have applied next generation sequencing, a thorough understanding of the MDV lake microbial diversity and community structure is currently lacking. Here we used Illumina MiSeq sequencing of the 16S and 18S rRNA genes combined with a microscopic survey of key eukaryotes to compare the community structure and potential interactions among the bacterial and eukaryal communities within the water columns of Lakes Bonney (east and west lobes, ELB, and WLB, respectively) and Fryxell (FRX). Communities were distinct between the upper, oxic layers and the dark, anoxic waters, particularly among the bacterial communities residing in WLB and FRX. Both eukaryal and bacterial community structure was influenced by different biogeochemical parameters in the oxic and anoxic zones. Bacteria formed complex interaction networks which were lake-specific. Several eukaryotes exhibit potential interactions with bacteria in ELB and WLB, while interactions between these groups in the more productive FRX were relatively rare.

“…Strain X12M-4 T was most closely related to the members of the genus Maritimibacter , followed by the members of the genera Roseibacterium and Tropicimonas . Two strains representing members of the genus Roseibacterium contained C 16 : 0 and C 18 : 1 ω7 c as the major fatty acids (Mao et al , 2012; Suzuki et al , 2006). Strain X12M-4 T could be distinguished from members of the genus Roseibacterium by the presence of C 19 : 0 cyclo ω8 c as the major fatty acid.…”

A Gram-staining-negative, non-motile, strictly aerobic bacterium, strain X12M-4 T , was isolated from Xiaochaidan Lake, a salt lake (salinity 9.9 %, w/w) in Qaidam basin, Qinghai Province, China. Its taxonomic position was determined by using a polyphasic approach. Strain X12M-4 T was catalase-and oxidase-positive. Cells were rod-shaped, 0.5-0.8 mm wide and 1.1-1.6 mm long. Growth was observed in the presence of 0-11.0 % (w/v) NaCl (optimum, 5.0-6.0 %) and at 15-40 8C (optimum, 25 8C) and pH 6.5-9.5 (optimum, pH 7.0). No growth occurred at 10 8C or 45 8C. Strain X12M-4 T contained C 18 : 1 v7c, C 19 : 0 cyclo v8c and C 16 : 0 as the major fatty acids (.10.0 %). The predominant respiratory quinone was Q-10.The major polar lipids were phosphatidylcholine, phosphatidylglycerol, diphosphatidglycerol, an unknown aminolipid and an unidentified lipid. The DNA G+C content was 65.7 mol% (determined using T m). Strain X12M-4 T showed highest 16S rRNA gene sequence similarities to Maritimibacter alkaliphilus HTCC2654 T (96.7 %), Roseibacterium elongatum DSM 19469 T (96.4 %), Tropicimonas aquimaris DPG-21 T (95.6 %), 'Roseibacterium beibuensis' JLT1202r (95.6 %) and Tropicimonas sediminicola M97 T (95.5 %) and ,95.5 % to others. Phylogenetic trees based on 16S rRNA gene sequences indicated that strain X12M-4 T formed a robust cluster with M. alkaliphilus HTCC2654 T. On the basis of the data, it is concluded that strain X12M-4 T represents a novel species of the genus Maritimibacter, for which the name Maritimibacter lacisalsi sp. nov. is proposed. The type strain is X12M-4 T (5CGMCC 1.12922 T 5JCM 30555 T). To accommodate the novel species, the description of the genus Maritimibacter was emended.

“…The phylogenomic tree of strain CSW1921 T and related species was reconstructed using the up-to-date bacterial core gene set [18]. The genome sequence of the reference strains Rodophyticola porphyridii MA-7-27 T (GCF_003688285.1) [19], Boseongicola aestuarii BS-W15 T (GCF_900184815.1) [20], Litoreibacter ponti GJSW-31 T (GCF_003054285.1) [21], Nioella ostreopsis Z7-4 T (GCF_004000255.1) [22] and Roseibacterium beibuensis JLT1202r T (GCF_025000125.1) [23] were obtained from the NCBI database, and the genomes were used to analyse genomic variations in comparison to strain CSW1921 T . The average amino acid identity (AAI) values were calculated using the AAI calculator (http://enve-omics.ce.gatech.edu/aai/index [24]).…”

In this study, we report a Gram-stain-negative, rod-shaped, atrichous and aerobic bacterial strain named CSW1921T, which was isolated from the deep-sea water of a cold seep in South China Sea. Growth of strain CSW1921T occurred at 10.0–35.0 °C (optimum, 30 °C), pH 5.0–10.0 (optimum, pH 8.0–9.0) and with 0–9.0 % (w/v) NaCl (optimum, 1.0–2.0 %). Phylogenetic tree analysis based on 16S rRNA gene sequence or the genomic sequence indicated that strain CSW1921T belonged to the family Rhodobacteraceae and was closely related to Rhodophyticola porphyridii MA-7-27T (97.5 % sequence similarity). Genomic analysis indicated that strain CSW1921T contains a circular chromosome of 3 592 879 bp with G+C content of 60.5 mol%. The predominant respiratory quinone of CSW1921T was ubiquinone-10. The polar lipids of CSW1921T contained phosphatidylglycerol, three unidentified aminolipids, two unidentified phospholipids and two unidentified lipids. The major fatty acids of strain CSW1921T contained C16 : 0, C18 : 1 ω7c 11-methyl and summed feature 8 (C18 : 1 ω7c). The average nucleotide identity, DNA–DNA hybridization and average amino acid identity values between strain CSW1921T and members of its related species were 68.02–69.08 %, 12.7–12.9 % and 46.87–48.08 %, respectively, which were lower than the recommended threshold values for bacterial species or genus delineation. Phylogenetic, physiological, biochemical and morphological analyses suggested that strain CSW1921T represents a novel genus and a novel species of the family Rhodobacteraceae , and the name Fontisubflavum oceani gen. nov., sp. nov. is proposed with the type strain CSW1921T (=MCCC 1K08371T=KCTC 92834T).
