Abstract:
An SRB community (SRB-2) was enriched from marine sediment for the treatment of sulfate-rich wastewater of high salinity, and the effect of salinity, temperature, pH value, carbon source, concentration of sulfate and the form of Fe on the activity of SRB-2 was studied. The results show that SRB-2 is a halophilous and moderately mesophilous SRB community. The optimal conditions for its growth are as follows: temperature of 30-40 degrees C and pH value of 7.4-8.3; it can endure 5,200 mg/L SO4(2-) and 60g/L NaCl. Zero-valent Fe can promote the reductive activity of SRB-2, while Fe2+ inhibits that. SEM and optical microscopic measurements indicate many rod-shaped and spiral bacteria on the surface of padding in reactor and black sticky substance composed of rod-shaped bacteria on the bottom of reactor. This sticky substance might be cumulus of culture SRB-2-64 (GenBank accession number: EU167911).
