Abstract
Taxonomical studies on ten strains of hydrocarbon-utilizing bacteria reported in previous paper, which produced various kinds of amino acid, were carried out. They were Achromobacter cycloclastes, Achromobacter delmarvae, Bacillus species, Corynebacterium species, Micrococcus species. Many of them were not identical with the species which are described in Bergey's Manual of 7th Edition.
