Embodiment Construction
[0020] The sulfate-reducing bacteria (Desulfovibrio vulgaris Hildenborough, DvH) used in the present invention is a strict anaerobic bacteria, which is diluted with 50% glycerol at a ratio of 1:1 and stored in a freezer at minus 80 degrees Celsius.
[0021] After taking out the strain and thawing at room temperature, take 0.2 mL and insert it into an anaerobic tube containing 10 mL of LS4D medium, and cultivate it in a 37°C incubator for 48 hours, at which time the activity of the bacteria is the best.
