The metabolism of Desulphovibrio desulphuricans does not appear to have been studied extensively. Stephenson and Stickland (1931) and Sisler and ZoBell (1950) showed that the organism can use gaseous hydrogen as a reducing agent for sulfate reduction. By growing cultures for several generations in mineral salt solution containing less than one part per million of sulfate, Sisler and ZoBell (195...

The centrosymmetric crystal structure of the novel semi-organic compound, 3C(3)H(5)N(2)S(+)·HSO(4) (-)·SO(4) (2-)·H(2)O, is based on chains of alternating anions and water mol-ecules (formed by O-H⋯O hydrogen bonds). The chains are inter-connected with the 2-amino-1,3-thia-zolium cations via strong N-H⋯O and weak C-H⋯O hydrogen-bonding inter-actions into a three-dimensional network.

The structure of synthetic disodium magnesium disulfate decahydrate at 180 K consists of alternating layers of water-coordinated [Mg(H(2)O)(6)](2+) octahedra and [Na(2)(SO(4))(2)(H(2)O)(4)](2-) sheets, parallel to [100]. The [Mg(H(2)O)(6)](2+) octahedra are joined to one another by a single hydrogen bond, the other hydrogen bonds being involved in inter-layer linkage. The Mg(2+) cation occupies...

A bacterial mixed culture reductively dechlorinating trichlorobenzenes was established in a defined, synthetic mineral medium without any complex additions and with pyruvate as the carbon and energy source. The culture was maintained over 39 consecutive transfers of small inocula into fresh media, enriching the dechlorinating activity. In situ probing with fluorescence-labeled rRNA-targeted oli...
