Effects of pH, Retention Time, Initial Concentration, Temperature and Biomass Dosage on Lead Adsorption by Pseudomonas sp

Biosorption is the ability of biological materials to accumulate heavy metals from wastewater through metabolically mediated or physico-chemical pathways. Here, Heavy metals are considered to be the common contaminant of ecosystem due to their toxicity and it is necessary to remove those metals from environment. Among various metals, lead was considered to be common contaminant which causes severe toxicity. Hence this toxic metal was biosorbed using a microorganism such as Pseudomonas sp., this is done by performing various effective tests. Dithizone is an effective method used to remove lead from any contaminated medium. Minimum Inhibitory Concentration (MIC) of the organism was identified by varying the concentration of the metal. The percentage removal of metal by Pseudomonas sp. was known by calculating the specific temperature, time, dosage and pH in which the organism had the ability to remove maximum metal from the solution. Finally lead was biosorbed by Pseudomonas sp., from contaminated water.
