Proposal of Vibrionimonas magnilacihabitans gen. nov., sp. nov., a curved Gram-stain-negative bacterium isolated from lake water

Abstract

Proposal of Vibrionimonas magnilacihabitans gen. nov., sp. nov., a curved Gram-stain-negative bacterium isolated from lake water A mesophilic bacterium appearing as curved rod-shaped cells was isolated from Lake Michigan water. It exhibited highest similarities with Sediminibacterium ginsengisoli DCY13 T (94.4 %); Sediminibacterium salmoneum NJ-44 T (93.6 %) and Hydrotalea flava CCUG 51397 T (93.1 %) while similarities with other recognized species were ,92.0 %. The primary polar lipid was phosphatidylethanolamine, with moderate amounts of two unidentified glycolipids, three unknown polar lipids, one unknown aminophospholipid and one aminolipid. The primary respiratory quinone was MK-7 and sym-homospermidine was the primary polyamine. The major cellular fatty acids were iso-C 15 : 1 G, iso-C 15 : 0 , iso-C 16 : 0 3-OH and iso-C 17 : 0 3-OH, with moderate amounts of iso-C 16 : 0 . The presence of glycolipids differentiated the novel strains from related genera. The DNA mol% G+C content of the type strain MU-2 T was 45.2. Results for other phenotypic and molecular analyses indicated that strain MU-2 T is a representative of a novel genus and species for which the name Vibrionimonas magnilacihabitans is proposed. The type strain is MU-2 T (5NRRL B-592315DSM 22423).

Pseudobacter ginsenosidimutans gen. nov., sp. nov., isolated from ginseng cultivating soil

“…Similarly, some affiliates of this family show diphosphatidylglycerol (DPG) and phosphatidylethanolamine (PE) as the major polar lipids. At the time of writing, the family Chitinophagaceae contained 31 genera including the following recently described genera with validly published names: Hydrobacter (Eder et al, 2015), Parasediminibacterium (Kang et al, 2016), Flaviaesturariibacter (Kang et al, 2015), Arachidicoccus (Madhaiyan et al, 2015), Thermoflavifilum (Anders et al, 2014), Vibrionimonas (Albert et al, 2014) and Cnuella (Zhao et al, 2014). Based on 16S rRNA gene sequence similarity, the family Chitinophagaceae possesses not only a large number of genera but also shows wide phylogenetic extent between species (minimum 90 %) in the family (Hanada et al, 2014).…”

Parasediminibacterium paludis gen. nov., sp. nov., isolated from wetland

“…S1, available in the online Supplementary Material). Strain HME6815 T differed from the genus Sediminibacterium by the absence of unidentified phospholipids and pattern of unidentified aminolipids, unidentified aminophospholipid and unidentified polar lipids (Kim et al, 2013;Kang et al, 2014;Albert et al, 2014).…”

“…At the time of writing, the family Chitinophagaceae comprises 24 genera with validly published names, including the recently identified genera Arachidicoccus (Madhaiyan et al, 2015), Asinibacterium (Lee et al, 2013), Cnuella (Zhao et al, 2014), Flaviaesturariibacter (Kang et al, 2015), Heliimonas (Leandro et al, 2013), Hydrobacter (Eder et al, 2015), Parafilimonas (Kim et al, 2014), Taibaiella (Zhang et al, 2013), Thermoflavifilum (Anders et al, 2014) and Vibrionimonas (Albert et al, 2014). Members of the family Chitinophagaceae are aerobic or facultatively anaerobic, usually non-motile, rod-shaped and contain menaquinone-7 (MK-7) as the isoprenoid quinone, and iso-C 15 : 0 , iso-C 17 : 0 3-OH and iso-C 15 : 1 G as the major fatty acids (Kämpfer et al, 2011;Kim et al, 2014).…”

Filimonas aurantiibacter sp. nov., an orange-pigmented bacterium isolated from lake water and emended description of the genus Filimonas

“…They reported that Betaproteobacteria predominated, followed by Bacteroidetes and Alphaproteobacteria. There are however, no published reports that characterized the microbial community in Lake Michigan potable water, although Albert et al (2010Albert et al ( , 2013Albert et al ( , 2014 have reported the isolation of several novel bacterial species and a novel genus of bacteria from Lake Michigan potable water.…”
