A novel facultatively psychrophilic bacterium, strain S-1, which
exhibits extraordinarily high catalase activity was isolated from the drain pool of a fish product processing plant that uses H2O2 as a bleaching and microbicidal agent. The
catalase activity of the isolate was 1 or 2 orders of magnitude higher
than those of Corynebacterium glutamicum,
Staphylococcus aureus, Pseudomonas fluorescens,
and five other species tested in this study. The strain seemed to
possess only one kind of catalase, according to the results of
polyacrylamide gel electrophoresis of the cell extract. The optimum
temperature for catalase activity was about 30°C, which was about
20°C lower than that for bovine catalase activity. Electron
microscopic observation revealed that the surface of the microorganism
was covered by blebs. Although the isolate was nonflagellated, its
taxonomic position on the basis of physiological and biochemical
characteristics and analysis of 16S rRNA sequence and DNA-DNA
relatedness data indicated that strain S-1 is a new species belonging
to the genus Vibrio. Accordingly, we propose the name
Vibrio rumoiensis. The type strain is S-1 (FERM P-14531).
