Abstract
We propose the name Pseudomonas lundensis for a new species of gram-negative, polarly flagellated, chemoorganotrophic, rod-shaped bacteria that were isolated from refrigerated meat. Strains of P. lundensis are capable of respiratory but not fermentative metabolism; they grow at 0°C, produce fluorescent pigments, catalase, and cytochrome c oxidase, and possess an arginine dihydrolase system. The mean guanine-plus-cytosine content of the deoxyribonucleic acids (DNAs) of 12 strains was 59.1 mol% (standard deviation, 0.7 mol%). Numerical phenotypic studies performed with 60 strains and DNA-DNA hybridization experiments with 12 strains (data separately published) revealed a tight phenotypic and genotypic cluster. P. lundensis is related to Pseudomonas fragi and the Pseudomonas fluorescens DNA-DNA homology group, and characteristics which differentiate these organisms and Pseudomonas aeruginosa are given. The type strain is strain 138 of Molin and Ternström (= 573 = CCM 3503); it was isolated from beef and has a guanine-plus-cytosine content of 60 mol %.
