- An obligately aerobic, chemoheterotrophic, mesophilic prosthecate bacterium, designated strain CGM1-3ENT, was isolated from the enrichment cultures of forest soil from Cheonggyesan Mountain, Republic of Korea. Cells were Gram-reaction-negative, motile rods (1.3–2.4 µm long by 0.30–0.75 µm wide) with single flagella. The strain grew at 10–37 °C (optimum 25–30 °C) and at pH 4.5–9.5 (optimum 5.0–7.0). The major cellular fatty acids were C16 : 0, C18 : 1ω7c 11-methyl, C12 : 1 3-OH and summed feature 8 (comprising C18 : 1ω7c/C18 : 1ω6c). The genomic DNA G+C content of strain CGM1-3ENT was 63.7 mol%. The closest phylogenetic neighbour to strain CGM1-3ENT was identified as Asticcacaulis biprosthecium DSM 4723T (97.2 % 16S rRNA gene sequence similarity) and the DNA–DNA hybridization value between strain CGM1-3ENT and A. biprosthecium DSM 4723T was less than 24.5 %. Strain CGM1-3ENT used d-glucose, d-fructose, sucrose, maltose, trehalose, d-mannose, d-mannitol, d-sorbitol, d-galactose, cellobiose, lactose, raffinose, fumarate, pyruvate, dl-alanine and glycerol as carbon sources. Based on data from the present polyphasic study, the forest soil isolate CGM1-3ENT is considered to represent a novel species of the genus Asticcacaulis, for which the name Asticcacaulis solisilvae sp. nov. is proposed. The type strain is CGM1-3ENT ( = AIM0088T = KCTC 32102T = JCM 18544T).
