Abstract

We compared non-methane-, non-methanol-, and methylamine-utilizing bacteria, including , a tetramethylammonium-utilizing bacterium, and an -dimethylformamide-utilizing bacterium. These bacteria are gram-negative, nonsporeforming, subpolarly flagellated, rod-shaped organisms. Reproduction occurs by budding. The DNA base compositions are 62 to 64 mol% guanine plus cytosine. The cellular fatty acids contain a large amount of C acid. The major hydroxy acid is 3-OH C acid. The major ubiquinone is ubiquinone Q-10. These bacteria are clearly separated from authentic species ( rRNA group) on the basis of utilization of methylamine, morphological and chemotaxonomic characteristics, DNA-DNA homology, and rRNA-DNA homology. They were divided into three subgroups on the basis of their physiological characteristics and DNA-DNA homology data. A new genus, , and three new species, comb. nov., sp. nov., and sp. nov., are proposed. The type species of gen. nov. is , with type strain JCM 7852. The type strain of is strain TH-3 (= JCM 7854), and the type strain of is strain DM-81 (= JCM 7853).
