Development of a Pseudomonas sp. for aerobic chromate reduction

  • Published:
Biotechnology Techniques

Summary

Shake flask cultures using a chromate resistant isolate identified as Pseudomonas sp. in defined medium containing 60 mg Cr(VI)/1 gave maximum chromate reduction of 87% at 40°C and pH 9 in 72 h with urea as nitrogen source. Continuous culture at 30 C, pH 7.2–7.6 and dilution rate of 0.014/h in a 2-1 chemostat with the same isolate showed 81% chromate reduction with feed containing 124 mg Cr(VI)/1.
