Two New Species of Pseudomonas: P. oryzihabitans Isolated from Rice Paddy and Clinical Specimens and P. luteola Isolated from Clinical Specimens

Abstract

Two new Pseudomonas species which were isolated from rice paddy and clinical specimens (groups Ve-2 and Ve-1) are described. Strains of Pseudomonas oryzihabitans sp. nov. are yellow-pigmented, oxidase-negative, nonsporeforming, gram-negative, polarly monotrichously flagellated, rod-shaped organisms with deoxyribonucleic acid base compositions ranging from 63.9 to 65.6 mol% guanine plus cytosine, ubiquinone Q-9, major cellular fatty acids consisting of C18:1 acid, C16:0 acid, and C16:1 acid, and 3-hydroxy acids consisting of 3-OH-C10:0 acid and 3-OH-C12:0 acid. Strains of this species were isolated from rice paddy and clinical specimens (group Ve-2). The type strain of this species is strain KS0036 (= L-l = AJ 2197 = IAM 1568 = JCM 2952). Strains of Pseudomonas luteola sp. nov. are yellow-pigmented, oxidase-negative, nonsporeforming, gram-negative, polarly multitrichously flagellated, rod-shaped organisms with deoxyribonucleic acid base compositions ranging from 55.4 to 55.9 mol% guanine plus cytosine, ubiquinone Q-9, major cellular fatty acids consisting of C18:1 acid, C16:0 acid, and C16:1 acid, and hydroxy acids consisting of 3-OH-C10:0 acid and 3-OH-C12:0 acid. Strains of this species were isolated from clinical specimens (group Ve-1). The type strain of this species is strain KS0921 (= G. L. Gilardi 4239 = IAM 13000 = JCM 3352).
