Sphingobacterium psychroaquaticum sp. nov., a psychrophilic bacterium isolated from Lake Michigan water

Abstract

A psychrophilic, Gram-negative bacterium, designated MOL-1 T , was isolated from water of Lake . The major cellular fatty acids were iso-C 15 : 0 , iso-C 17 : 0 3-OH and summed feature 3 (iso-C 15 : 0 2-OH and/or C 16 : 1 v7c). Menaquinone MK-7 is the predominant respiratory quinone, while symhomospermidine is the predominant polyamine. The polar lipid profile is composed of the predominant lipids phosphatidylethanolamine and unidentified polar lipid L2, with moderate amounts of unidentified polar lipids L1, L5 and L6 and unidentified aminophospholipids APL1 and APL2 and minor to trace amounts of unidentified polar lipids L3, L4, L7, L8, L9 and L10, unidentified phospholipid PL4 and unidentified aminophospholipid APL3. After molecular and phenotypic studies, including chemotaxonomic analyses, it was concluded that strain MOL-1 T represents a novel Sphingobacterium species, for which the name Sphingobacterium psychroaquaticum sp. nov. is proposed. The type strain is MOL-1 T (5NRRL B-59232 T 5DSM T).

Sphingobacterium zeae sp. nov., an endophyte of maize

“…The quinone system consisted of menaquinone MK-7 (99 %) and MK-6 (1 %). Both polyamine pattern (Hamana & Matsuzaki, 1991;Albert et al, 2013) and quinone system were in accordance with the characteristics of other species of the genus Sphingobacterium. In the polar lipid profile (Fig.…”

Beneficial microbiomes: Biodiversity and potential biotechnological applications for sustainable agriculture and human health

“…The low-temperature habitat represents hot spots of biodiversity, and several novel cold-adapted microbial species have been sort out from cold environments including Cellulophaga algicola [40], Cryobacterium roopkundense [41], Exiguobacterium soli [42], Flavobacterium frigidarium [43], Flavobacterium psychrolimnae [44], Glaciimonas frigoris [45], Hymenobacter roseosalivarius [46], Lacinutrix jangbogonensis [47], Massilia eurypsychrophila [48], Octadecabacter arcticus [49], Oleispira antarctica [50], Pedobacter arcticus [51], Pseudomonas extremaustralis [52], Psychrobacter pocilloporae [53], Psychromonas ingrahamii [54], Sphingobacterium psychroaquaticum [55], and Sphingomonas glacialis [56]. Along with novel species of psychrotrophic microbes, some microbial species such as Arthrobacter nicotianae, Brevundimonas terrae, Paenibacillus tylopili, and Pseudomonas cedrina have been isolated and characterized for multifarious PGP attributes at low temperatures from cold deserts of NW Himalayas [7].…”

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.…”

“…If turbidity was observed, tubes were streaked to PCA to determine the identity of the bacterium present. Aerobic acid production from sugars was performed using the method described in Albert et al (2013) with incubation at 25 C for up to 14 days. Production of cell-bound orange pigments was determined by the technique of Yabuuchi et al (1983).…”
