Abstract

A total of 46 glutamate-degrading strains of the genus , including 36 new isolates, were examined for deoxyribonucleic acid (DNA)-DNA homology, protein patterns produced by polyacrylamide gel electrophoresis, and physiological characteristics in order to determine the differences between and "." Thirty-four newly isolated strains could be assigned to the "" group; two strains were classified as nontoxigenic strains. The levels of DNA-DNA homology between and "" were only 10 to 19%, and the protein patterns showed that there were great differences between both groups and other glutamate-degrading species. Biochemical tests supported these results. In contrast to , all "" strains fermented carbohydrates (at least glucose and maltose); they also produced lipase and degraded ethanolamine. Moreover, , like other glutamate-degrading species, needed a higher concentration of yeast extract than "" when it was grown on glutamate. On the basis of our results we propose sp. nov., nom. rev. The type strain is strain NCTC 543 (= DSM 4474).
