| Abstract |
An aerobic, budding, dark pink to red-pigmented bacterium was isolated from an acidic boreal Sphagnum peat bog anddesignated strain SP5T. Cells of this strain were non-motile spheres that were uniformly covered with crateriform pits andfimbria, and tended to form aggregates during growth in liquid media. Strain SP5T was capable of growth between pH 4.0and pH 6.8 (optimum at pH 5.5–6.0) and at temperatures between 10 and 30 ?C (optimum at 20–25 ?C). The preferred growthsubstrates were sugars and some heteropolysaccharides. The major fatty acids were C20 : 1!9c, C16 : 1!9c and C16 : 0, and themajor polar lipid was trimethylornithine. Cells contained also significant amounts of bound (!-1)OH-C30 : 1 fatty acid. Thequinone was menaquinone-6, and the G+C content of the DNA was 60.7 mol%. Strain SP5T was a member of the orderPlanctomycetales and belonged to the phylogenetic lineage defined by the genus Gemmata. It displayed 88 and 89% 16SrRNA gene sequence similarity to Gemmata obscuriglobusUQM 2246T and ‘Gemmata massiliana’ IIL30, 89% to Zavarzinellaformosa A10T and 86% to Telmatocola sphagniphila SP2T. However, strain SP5T differed from members of these genera bycell morphology, substrate utilization pattern and fatty acid composition. Based on these data, the novel isolate should beconsidered as representing a novel species of a new genus of planctomycetes, for which the name Fimbriiglobus ruber gen.nov., sp. nov, is proposed. The type strain is SP5T (=LMG 29572T=VKM B-3045T). We also suggest the establishment of anovel family, Gemmataceaefam. nov., which includes the phylogenetically related genera Gemmata, Zavarzinella, Telmatocolaand Fimbriiglobus. |
