Abstract
Batch cultures of Desulfovibrio vulgaris, carried out in a 5‐litre stirred fermenter, are described. Bacterial counts and sulphide formation are reported for experiments carried out under a selection of controlled Eh and pH conditions. Specific growth and sulphide formation rates are determined and compared. Variations in the growth rates under the different controlled conditions are examined and discussed in terms of product inhibition by sulphide. A relatively high specific rate of exponential growth was observed at Eh = ‐ 150 mV and pH=6.95, when sulphide inhibition was believed to be at a minimum.Keywords
