Effect of Mercury concentration on P. putida growth in Mercury removal

Mercury is a toxic pollutant emitted from industrial sectors to the environment and distributed globally. The potential for biological treatment of industrial wastewater contaminated with mercury was evaluated using Pseudomonas putida (P. putida) under various conditions in a bioreactor. The effect...
