Another aspect of metal form which may influence toxicity is the valence of metal ions and their compounds. Panda and Sarkar [51] found Cr 3+ to be less toxic to K. aerogenes than CrO 4 2- . A 24% reduction in glucose oxidation by the bacteria in a laboratory scale continuous flow reactor was induced by 12.4 mg/L Cr 3+ , whereas only 4.9 mg/L CrO 4 2- caused a reduction of 45% [52].
