Effect of various parameters on removal of chromium (vi) using pseudomonas aeruginosa 4442

Industrialization and human activities makes intense impact on the environment by disposing industrial effluent containing heavy metals. Remedial procedures using biomaterials, such as, bacteria, algae, fungi, yeast, and agricultural waste biomass are regarded as a cost-effective technique for the treatment of high volume and low concentration of complex waste water containing heavy metals. In current research a microbial remedy is suggested to treat the chromium bearing effluent which includes application of bacterial culture i.e. Pseudomonas aeruginosa 4442 and effect of different condition was studied on biosorption of chromium. The major findings include parameter which showed highest percent accumulation of chromium i.e. Nutrient broth (82%), Glucose (72%), Yeast extract (67%), incubation period (120h), shaking conditions, 20h active culture ( 65%), Mn2+(88%) and Cu2+(81%) and pretreatment of culture with triton (0.1%) given highest accumulation(72%). The recent study proposes the application of Pseudomonas aeruginosa 4442 for biosorption of chromium with obtained optimum parameters.
