Controlling water pollution is one of the greatest concerns to scientists as the water is of prime and foremost necessity of life. Inorganic and organic substances discharged from various sectors like domestic, agriculture and industrial sectors are the major classes of pollutants in all aqua systems. Conventional treatment technologies for removal of organic and inorganic pollutants from aqueous solution are not economical and they generate sludge in huge quantity. Biodegradation is considered as an effective and attractive technology to remove organic and inorganic pollutants from aqueous solutions in recent days. Large no. of microorganisms viz., bacteria, fungi, yeasts were found to be successful in removal of organic and inorganic pollutants to different extents from aqueous environment. The Immobilization of cells on a suitable support simplify the treatment of liquid waste as the entrapment of living cells increases the retention time of cells on contaminated water. The present work is the compilation of investigations of co-immobilized cells of Saccharomyces cerevisiae and Bacillus coagulans as biomass for the removal of phosphates, nitrates and organic pollutants from aqueous solutions. The variations in pH, D.O., C.O.D., B.O.D. and concentration of different inorganic substances like nitrates and phosphates during incubation period were reported.
