Abstract
The carbon monoxide-utilizing hydrogen bacterium DSM 1083 (Carboxydobacterium strain Z-1062), the type strain of Seliberia carboxydohydrogena, was found to be a monotrichous, nonbudding, rarely screw-sculptured bacterium which did not convert lactose to 3-ketolactose and which was not pathogenic for tomatoes. Because of these properties and its strictly aerobic metabolism, it is proposed that this organism be transferred from the genus Seliberia to the genus Pseudomonas as Pseudomonas carboxydohydrogena (Sanjieva and Zavarzin) comb. nov. This species is distinctly different from other CO-utilizing pseudomonads with regard to guanosine plus cytosine content, substrate utilization spectrum, and extent of star formation.
