| Abstract: | Desulfovibrio strain JJ isolated from estuarine sediment differed from all other described Desulfovibrio species by the ability to degrade fructose. The oxidation was incomplete, leading to acetate production. Fructose, malate and fumarate were fermented mainly to succinate and acetate in the absence of an external electron acceptor. The pH and temperature optima for growth were 7.0 and 35° C respectively. Strain JJ was motile by means of a single polar flagellum. The DNA base composition was 64.13% G+C. Cytochrome c
3 and desulfoviridin were present. These characteristics established the isolate as a new species of the genus Desulfovibrio, and the name Desulfovibrio fructosovorans is proposed. |
