TL;DR: The novel strain isolated from the trophosome of a tubeworm in Kagoshima Bay, Japan, represents a novel species of a new genus in the family Sphingomonadaceae, for which the name Parasphingopyxis lamellibrachiae gen. nov., sp.
Abstract: A Gram-stain-negative, aerobic, motile, orange-pigmented, slightly halophilic, rod-shaped bacterium, designated strain JAMH 0132T, was isolated from the trophosome of a tubeworm in Kagoshima Bay, Japan, and its taxonomic position was investigated using a polyphasic approach. The novel strain grew optimally at 28–30 °C and with about 2.0 % (w/v) NaCl. Chemotaxonomic analysis showed that Q-10 was the predominant respiratory quinone and that C18 : 1ω7c, C16 : 0 2-OH and C16 : 0 were the major fatty acids. Sphingoglycolipid, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine were the major polar lipids. The genomic DNA G+C content was 60.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JAMH 0132T belonged to the family
Sphingomonadaceae
, within the class
Alphaproteobacteria
. The novel strain appeared most closely related to
Sphingopyxis baekryungensis
SW-150T (95.1 % 16S rRNA gene sequence similarity) and showed less sequence similarity with representatives of the genera
Blastomonas
,
Sphingomonas
,
Sphingosinicella
and
Novosphingobium
(<94.8 %). In having no detectable polyamine, strain JAMH 0132T differed from members of all genera currently in the family
Sphingomonadaceae
. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain JAMH 0132T represents a novel species of a new genus in the family
Sphingomonadaceae
for which the name Parasphingopyxis lamellibrachiae gen. nov., sp. nov. is proposed. The type strain of Parasphingopyxis lamellibrachiae gen. nov., sp. nov. is JAMH 0132T ( = JCM 15549T = NCIMB 14486T).

TL;DR: The isolate of a Gram-stain-negative, aerobic bacterial strain, 912T, from a soil sample taken from Rambla Salada (Murcia), south-eastern Spain, by using the dilution-to-extinction method represents a novel species of the genus Blastomonas, for which the name blastomonas quesadae sp.
Abstract: We isolated a Gram-stain-negative, aerobic bacterial strain, 912T, from a soil sample taken from Rambla Salada (Murcia), south-eastern Spain, by using the dilution-to-extinction method. Cells of the strain were motile with a polar flagellum, short rod-shaped, catalase- and oxidase-positive and grew at NaCl concentrations within the range 0–5 % (w/v) (optimum 3 %, w/v), at 4–32 °C (optimum 30 °C) and at pH 6–9 (optimum pH 7); bacteriochlorophyll a was produced. Analysis of the 16S rRNA gene sequence indicated that this strain belonged to the genus
Blastomonas
in the class
Alphaproteobacteria
. Its closest relatives were
Blastomonas natatoria
EY 4220T,
Blastomonas ursincola
KR-99T and
Blastomonas aquatica
PE 4-5T, to which the strain showed 16S rRNA gene sequence similarity values of 95.9, 95.8 and 95.1 %, respectively. The DNA G+C content was 63 mol%. The major fatty acids of strain 912T were C18 : 1ω7c/C18
: 1ω6c, C16 : 1ω7c/C16
: 1ω6c, C16 : 0 and C17 : 1ω6c. The predominant isoprenoid quinone was ubiquinone 10 (Q-10). The polar lipids contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, phosphoglycolipid, one unidentified phospholipid and two unidentified polar lipids. Based on the phylogenetic, genotypic, phenotypic and chemotaxonomic data, the strain represents a novel species of the genus
Blastomonas
, for which the name Blastomonas quesadae sp. nov. is proposed. Strain 912T (=CECT 9186T=LMG 29921T) is the type strain.

TL;DR: The draft genome of Blastomonas sp.
Abstract: Blastomonas is a strictly aerobic bacteriochlorophyll a-producing genus within the alpha-4 Proteobacteria. Here we report the first genome sequence from this genus. The draft genome of Blastomonas sp. strain AAP53 contains a split photosynthesis gene cluster and two gene clusters encoding a flagellar system. Genes for the autotrophic CO2 fixation pathway are absent.

TL;DR: With the new methods for assembling sequence data from metagenomic samples, the genomic study of heterotrophic bacterium-cyanobacterium associations can now be improved.
Abstract: With the new methods for assembling sequence data from metagenomic samples, the genomic study of heterotrophic bacterium-cyanobacterium associations can now be improved In this work, the draft genome sequence of Blastomonas sp strain CACIA 14H2, obtained from a nonaxenic culture of a Cyanobium sp, is presented

TL;DR: A pale yellow, aerobic bacterium, strain M0-2(T), was isolated from a till sample and is considered to represent a novel species in a new genus in the family Sphingomonadaceae for which the name Parablastomonas arctica gen. nov., sp.
Abstract: A pale yellow, aerobic bacterium, strain M0-2T, was isolated from a till sample. Its taxonomic position was investigated by using a polyphasic approach. Cells were Gram-stain-negative, rod-shaped and motile. Cells reproduced by budding or asymmetrical cell division. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain M0-2T belonged to the family
Sphingomonadaceae
and was closely related to species of the genera
Novosphingobium
(96.4–92.0 %) and
Blastomonas
(94.6 %),
Sphingopyxis witflariensis
W-50T (94.0 %),
Sphingosinicella soli
KSL-125T (93.6 %) and
Sphingomonas astaxanthinifaciens
TDMA-17T (93.5 %). Ubiquinone-10 (Q-10) was the predominant respiratory quinone. The major fatty acids were summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c, 31.9 %), summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c, 19.8 %) and C14 : 0 2-OH (8.9 %). Sphingoglycolipid, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine were the major polar lipids. Spermidine was the major polyamine observed in the cell. The genomic DNA G+C content was 47.5 mol%. On the basis of phylogenetic relationships and the low DNA G+C content compared with most other genera of the family
Sphingomonadaceae
, combined with phenotypic and chemotaxonomic data, strain M0-2T is considered to represent a novel species in a new genus in the family
Sphingomonadaceae
for which the name Parablastomonas arctica gen. nov., sp. nov. is proposed. The type strain of Parablastomonas arctica gen. nov., sp. nov. is M0-2T ( = CCTCC AB 2012968T = NRRL B-59110T).
