Abstract

The extent of hybrid formation between the ribosomal ribonucleic acid (r-RNA) of Hyphomicrobium strain B-522 and deoxyribonucleic acid (DNA) from bacteria of 21 different genera was examined. Three generalized groupings were formed. Group I (72-100%) consisted entirely of other strains of Hyphomicrobium. Representatives of the genera Rhodopseudomonas, Chromatium, Caulobacter, Prosthecomicrobium, Rhodomicrobium, Hyphomonas, and Hyphomicrobium made up group II (49-69%). The remaining Gram-negative, Gram-positive, and cell wall--less bacteria fell into group III (12-40%). The taxonomic implications of these results are discussed.

摘要

研究了生丝微菌属B-522菌株的核糖体核糖核酸（r-RNA）与来自21个不同属细菌的脱氧核糖核酸（DNA）之间杂交形成的程度。形成了三个大致的分组。第一组（72 - 100%）完全由生丝微菌的其他菌株组成。红假单胞菌属、着色菌属、柄杆菌属、突柄微菌属、红微菌属、生丝单胞菌属和生丝微菌属的代表构成了第二组（49 - 69%）。其余的革兰氏阴性菌、革兰氏阳性菌和无细胞壁细菌归入第三组（12 - 40%）。讨论了这些结果的分类学意义。
