| Abstract: | Production of an intracellular polysaccharide was observed during cultivation of a marine, obligately chemolithoautotrophic hydrogen-oxidizing bacterium, Hydrogenovibrio marinus, under nitrogen or magnesium starvation or oxygen limitation in a continuous gas supply. The polysaccharide formed in oxygen-limited cells was isolated and shown to be composed of only glucose. Instrumental and enzymatic analyses revealed that the polysaccharide has a glycogen-like structure. |
