Six deep-yellow-pigmented strains were isolated from soil after enrichment on plasticized acetylated starch granules as a source of carbon. They showed very similar and unique fatty acid profiles, consisting almost exclusively of branched fatty acids. The strains consisted of small, motile rods, were oxidase- and catalase-positive, did not ferment sugars and were able to depolymerize starch and suspended acetylated starch in overlayer plates. The 16S rDNA sequence of a representative strain, strain LMG 19981T, showed 96.7% sequence similarity to that of Rhodanobacter lindaniclasticus, 96.0% to that of Frateuria aurantia and less than 92% to sequences of other members of the gamma-Proteobacteria. Repetitive extragenic palindromic DNA PCR fingerprinting revealed two groups, representatives of which showed 93% DNA-DNA reassociation with each other and less than 10% with Frateuria aurantia LMG 1558T. On the basis of phenotypic characteristics and the G+C content of the DNA, the strains could be differentiated from Frateuria aurantia and Rhodanobacter lindaniclasticus. The name Fulvimonas soli gen. nov., sp. nov. is proposed, with the type strain LMG 19981T (= DSM 14263T).
从以增塑乙酰化淀粉颗粒为碳源进行富集培养的土壤中分离出六株深黄色色素菌株。它们显示出非常相似且独特的脂肪酸谱，几乎完全由支链脂肪酸组成。这些菌株由小的、可运动的杆菌组成，氧化酶和过氧化氢酶呈阳性，不发酵糖类，并且能够在覆盖平板中使淀粉和解悬浮的乙酰化淀粉解聚。代表性菌株LMG 19981T的16S rDNA序列与林丹分解红杆菌（Rhodanobacter lindaniclasticus）的序列相似性为96.7%，与aurantia弗氏菌（Frateuria aurantia）的序列相似性为96.0%，与γ-变形菌纲其他成员的序列相似性低于92%。重复外显子回文DNA PCR指纹图谱显示有两组，每组的代表菌株彼此之间的DNA-DNA重结合率为93%，与aurantia弗氏菌LMG 1558T的重结合率低于10%。基于表型特征和DNA的G+C含量，这些菌株可与aurantia弗氏菌和林丹分解红杆菌区分开来。提出了新属名Fulvimonas soli及新种名，模式菌株为LMG 19981T（=DSM 14263T）。
