“…At time of writing, the genus Hephaestia contains only one validly named species [2]. Based on phylogenetic, chemotaxonomic, signature nucleotide and MALDI-TOF MS data, the type species of the genus Hephaestia could be differentiated clearly from related representatives of the genera Sphingomonas , Sphingobium , Sphingopyxis , Sphingosinicella and Novosphingobium [1]. Species of the genus Hephaestia possess ubiquinone-10 as the predominant respiratory lipoquinone, meso -diaminopimelic acid as the diagnostic diamino acid, and contain C 18 : 1 ω 7 c and C 17 : 1 ω 6 c as the major fatty acids.…”

Polar lipids are dominated by sphingoglycolipid and phosphatidylglycerol [1].

A Gram-stain-negative, aerobic, motile, rod-shaped bacterium, designated CMS5P-6T, was isolated from a surface-sterilized bark of Aegiceras corniculatum collected from Guangxi Zhuang Autonomous Region, PR China, and investigated by a polyphasic approach to determine its taxonomic position. Strain CMS5P-6T was found to grow optimally with 0–1 % (w/v) NaCl, at 30 °C and pH 6.0–7.0. Substrate mycelia and aerial mycelia were not formed, and no diffusible pigments were observed on the media tested. Phylogenetic analysis showed that strain CMS5P-6T showed high 16S rRNA gene sequence similarity of 96.7 % to Hephaestia caeni DSM 25527T and Sphingomonas colocasiea CC-MHH0539T. The average nucleotide identity, digital DNA–DNA hybridization and average amino acid identity values between strain CMS5P-6T and H. caeni DSM 25527T were 78.0, 21.7 and 70.8 %, respectively. The average nucleotide identity, digital DNA–DNA hybridization and average amino acid identity values between strain CMS5P-6T and S. colocasiea JCM 31229T were 74.0, 19.9 and 61.4 %, respectively. Phylogenomic analyses based on genome sequences showed that strain CMS5P-6T and H. caeni DSM 25527T formed a distinct cluster within the family Sphingomonadaceae and far away from S. colocasiea JCM 31229T. The DNA G+C content of strain CMS5P-6T was determined to be 65.6 mol%. The cell-wall peptidoglycan was found to contain meso-diaminopimelic acid as the diagnostic diamino acid and ubiquinone Q-10 was identified as the respiratory lipoquinone. The polar lipids were found to comprise diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, sphingoglycolipid and two unidentified aminolipids, and the major fatty acids were identified as C18 : 1 ω7c, C19 : 0 cycloω8c and C16 : 0. On the basis of phylogenetic, genomic, chemotaxonomic and phenotypic data, strain CMS5P-6T can be concluded to represent a novel species of the genus Hephaestia , for which the name Hephaestia mangrovi sp. nov. is proposed. The type strain is CMS5P-6T (=JCM 33125T=CGMCC 1.13868T).

Sphin.go.py'xis. N.L. neut. n. sphingosinum (from Gr. gen. n. sphingos , of sphinx, and suff. ‐ ine ) sphingosine; N.L. pref. sphingo ‐, pertaining to sphingosine; L. fem. n. pyxis ‐ idis , box, case, container; N.L. fem. n. Sphingopyxis , intended to mean box of sphingolipid‐containing life. Proteobacteria / Alphaproteobacteria / Sphingomonadales / Sphingomonadaceae / Sphingopyxis The cells are Gram‐stain‐negative, aerobic, rod shaped, nonsporulating, motile or nonmotile, and may be flagellated or nonflagellated. Excepting a few, most of them are oxidase‐, catalase‐, and DNase‐positive. Most of them are culturable and can easily grow on culture media such as Luria–Bertani, nutrient agar, tryptic soy agar, R2A, and veal infusion agar. Species of the genus Sphingopyxis can utilize a wide variety of carbon and nitrogen sources. The major polar lipids observed in Sphingopyxis spp. are phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylmonomethylethanolamine, and sphingoglycolipids. The major fatty acids include C 18:1 ω7 c , C 16:0 , C 17:1 ω 6 c , and C 14: 0 2‐OH. The major respiratory quinone observed is ubiquinone Q‐10. In most of the species, the major polyamine observed is spermidine with minor amount of spermine. Most of the members grow at moderate temperatures, while some prefer lower temperature for their growth. Growth can be observed in narrow pH range in some (close to pH 7) and wide range in remaining ones. GC content varies from 62.3 to 69.2% across the characterized species of Sphingopyxis . Members of this genus can grow in the presence or absence of NaCl which is also variable among members. DNA G + C content (mol%) : 62.40–66.44. Type species : Sphingopyxis macrogoltabida (Takeuchi et al., 2001).

A pale yellow bacterial strain, designated JJ-A5, was isolated form an agricultural soil from Jeju Island in Republic of Korea. Cells of the strain were Gram-stain-negative, motile, flagellated and rod-shaped. The strain grew at 15-30°C, pH 6.0-9.0, and in the presence of 0-1.5% (w/v) NaCl. Growth occurred on R2A, but not on Luria-Bertani agar, nutrient agar, trypticase soy agar and MacConkey agar. The strain utilized alachlor as a sole carbon source for growth. The strain JJ-A5 showed 16S rRNA gene sequence similarities lower than 95.4% with members of the family Sphingomonadaceae. Phylogenetic analysis showed that the strain belongs to the family Sphingomonadaceae and strain JJ-A5 was distinctly separated from established genera of this family. The strain contained Q-10 as dominant ubiquinone and spermidine as major polyamine. The predominant cellular fatty acids were summed feature 8 (Cω7c and/or Cω6c), summed feature 3 (Cω7c and/or Cω6c), 11-methyl Cω7c, C and C 2-OH. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, and phosphatidylcholine. The DNA G + C content of the strain was 62.7 mol%. On the basis of the phenotypic, genomic and chemotaxonomic characteristics, strain JJ-A5 is considered to represent a novel genus and species within the family Sphingomonadaceae, for which the name Tardibacter chloracetimidivorans gen. nov., sp. nov. is proposed. The type strain of Tardibacter chloracetimidivorans is JJ-A5 (= KACC 19450 = NBRC 113160).
