Summary

A microbiological process using Pseudomonas mendocina was developed for the removal of Cr(VI) from cooling tower effluent. The process, when carried out in a 20 liter continuous stirred tank reactor removed 25–100 mg chromate/l in 4.5–8 h with >99.9% efficiency in the presence of sugarcane molasses as nutrient. The process could sustain wide variations in pH (6.5–9.5), temperature (25°C–40°C) and was unaffected by commonly used biocides.
