Growth of Wolinella succinogenes with polysulphide as terminal acceptor of phosphorylative electron transport

AbstractPolysulphide was formed according to reaction (1), when tetrathionate was (1)

SEARCH FOR POLYTHIONATES IN CULTURES OF CHROMATIUM-VINOSUM AFTER SULFIDE INCUBATION

{\text{S}}_4 {\text{O}}_6^{2 - } + {\text{HS}}^ - \to 2{\text{S}}_2 {\text{O}}_3^{2 - } + {\text{S(O)}} + {\text{H}}^ +

Ion-pair chromatographic separation of polythionates SnO62- with up to thirteen sulphur atoms☆

added to an anaerobic buffer (pH 8.5) containing excess sulphide. S(O) denotes the zero oxidation state sulphur in the polysulphide mixture Sinfnsup2-. The addition of formate to the polysulphide solution in the presence of Wolinella succinogenes caused the reduction of polysulphide according to reaction (2). The bacteria grew in a medium containing formate and sulphide, (2)

Vibrational spectroscopic investigations of snse8-n molecules

when tetrathionate was continuously added. The cell density increased proportional to reaction (3) which represents the sum of reactions (1) and (3)
