The taxonomic positions of 10 strains of 3-ketolactose-forming bacteria which were isolated from the roots of plants (Rosa sp., Psychotria nairobiensis, Ardisia crispa, Prunus persica, and apple trees) were investigated. The DNA base compositions of these strains ranged from 64.0 to 65.7 mol%, the isoprenoid quinone of each strain was ubiquinone 10, 3-hydroxy fatty acids were lacking in the cellular fatty acids of these organisms, and all of the strains contained a sphingolipid with the long-chain base dihydrosphingosin. These are characteristics of the genus Sphingomonas. On the basis of morphological, physiological, and chemotaxonomic characteristics, together with DNA-DNA hybridization and 16S ribosomal DNA sequence comparison data, we propose the following four new species of the genus Sphingomonas: Sphingomonas rosa (type strain, IFO 15208) for the strains isolated from rose plants and formerly named [Agrobacterium rhizogenes]; Sphingomonas pruni (type strain, IFO 15498) for the strains isolated from Prunus persica; and Sphingomonas asaccharolytica (type strain, IFO 15499) and Sphingomonas mali (type strain, IFO 15500) for the strains isolated from apple trees. Two strains which were isolated from Psychotria nairobiensis and formerly named [Chromobacterium lividum] were identified as Sphingomonas yanoikuyae strains.
对从植物（蔷薇属、内罗毕九节、朱砂根、桃树和苹果树）根部分离出的10株产3-酮乳糖细菌的分类地位进行了研究。这些菌株的DNA碱基组成范围为64.0至65.7 mol%，各菌株的类异戊二烯醌均为泛醌10，这些微生物的细胞脂肪酸中缺乏3-羟基脂肪酸，并且所有菌株均含有一种带有长链碱二氢鞘氨醇的鞘脂。这些是鞘氨醇单胞菌属的特征。基于形态学、生理学和化学分类学特征，结合DNA-DNA杂交和16S核糖体DNA序列比较数据，我们提出鞘氨醇单胞菌属的以下四个新种：从玫瑰植物中分离出的菌株，以前命名为[发根农杆菌]，命名为蔷薇鞘氨醇单胞菌（模式菌株，IFO 15208）；从桃中分离出的菌株，命名为李鞘氨醇单胞菌（模式菌株，IFO 15498）；从苹果树中分离出的菌株，命名为解糖鞘氨醇单胞菌（模式菌株，IFO 15499）和苹果鞘氨醇单胞菌（模式菌株，IFO 15500）。从内罗毕九节中分离出的两株以前命名为[淡紫色杆菌]的菌株被鉴定为矢野鞘氨醇单胞菌菌株。
