摘要：

The sulfate reducing bacterium, Desulfovibrio desulfuricans NCIMB 8372, was cultured in a 1-L biochemical reactor. The reactor was operated in a sequential batch mode and the results of four sequential runs are presented (the first run was a recently inoculated reactor). Results fall within the range of published results, reaching sulfate reduction rates up to 2764.8 mg/L/day. The bacteria attached to the reactor walls and a method was proposed to evaluate the magnitude of the adhered cells fraction, which resulted in a value of 1.2-3.0 . 10(6) cells/cm2, a value that correlated well with cells counted in scanning microscope photographs taken from a tube in the reactor.
