以乳酸盐和硫酸盐为底物，在不同pH值(5.8~7.0)下培养硫酸盐还原菌(SRB)。在此pH范围内，确定了pH值对生长速率的影响；在pH为6.7时，生长速率最高。硫酸盐还原产生的硫化氢对SRB有直接和可逆的毒性作用。浓度为547 mg/L(16.1 mM)的硫化氢完全抑制了培养物的生长。比较了冰醋酸和硫化氢的缓蚀作用，并对相伴的缓蚀动力学进行了数学描述。
A culture of sulfate reducing bacteria (SRB) growing on lactate and sulfate was incubated at different pH values in the range of 5.8-7.0. The effect of pH on growth rate was determined in this pH range; the highest growth rate was observed at pH 6.7. Hydrogen sulfide produced from sulfate reduction was found to have a direct and reversible toxicity effect on the SRB. A hydrogen sulfide concentration of 547 mg/L (16.1 mM) completely inhibited the culture growth. Comparison between acetic acid and hydrogen sulfide inhibition is presented and the concomitant inhibition kinetics are mathematically described.
