Abstract
{Water pollution due to chemicals and microbes is one of the serious environmental problems, which has greatly impacted human health. Recorded history of contaminated drinking water supply has witnessed various microbial diseases. Drinking water samples were selected and samples were collected seasonally from water supply, storage tanks and distribution system. Physicochemical and microbiological analyses were conducted. E. coli, St. faecelis, A. flavus and A. niger were found to be highly resistance to Al3+. It was found that the maximum biosorption efficiency for E.coli and Streptococcus faecelis was achevied at concentrations 14.2 mg/l. Also it was found that the maximum biosorption efficiency for A. flavus and Alternaria alternata were at concentration 7.14 mg/l and A. niger was at 14.28 mg/l.It was found that the optimum temperature for Al3+ uptake by E.coli and St. faecelis was 35°C and the optimum temperature for Al3+ uptake by A. flavus was 35°Cand for A. niger and Alternaria alternata was 30°C.It was found that the removal of Al3+ from broth media was influenced by pH values. Maximum removal capacities were obtained at pH 7for St. faecelis. E.coli ,A. flavus, Alternaria alternata and A. niger were at pH 6. Maximum biosorption of Al3+ by E.coli and St. faecelis were occurred after 2days, whereas Al3+biosorption by A. flavus and A. niger were occurred after 9 days. Alternaria alternata was occurred after 5 days. Dead biomass of E.coli and St. faecelis recorded maximum adsorption from aqueous solution at Al3+ concentration of 21.4 and 14.28 mg/l respectively where dead mycelia of A. flavus and A. niger recorded maximum adsorption from aqoues solution at Al3+ concentration of 7.14 and 14.28 mg/l respectively.
