Abstract

Rod-shaped or slightly curved bacteria. Approximately 0.7-0.9X 2.0- 3.0 um. (See Fig.BXII.y.110). Cells may produce a capsule that is visible by India ink staining. Coccoid bodies may predominate in old cultures and are associated with a loss of viability. Poly-B-hydroxybutyrate is accumulated and may form small inclusions that are visible by phase-contrast microscopy. Motile by a single polar flagellum. Aerobic; however, fermentation tests with some sugars and sugar alcohols are weakly positive. Acid is produced slowly from some carbohydrates. Na+is required for growth. Oxidase and catalase positive. Phosphatase positive. Utilize some carbohydrates, polycyclic aromatic hydrocarbons, amino acids, organic acids, and sugar alcohols as sole carbon sources for chemoorganotrophic growth. Temperature range for known strains,
