BIOREMEDIATION OF INDUSTRIAL AND MUNICIPAL WASTE WATER USING BACTERIAL ISOLATES
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 5
Abstract
Bioremediation is a treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or non toxic substances. The microbes are effective in control of pollution due to waste water. The industrial and municipal waste water is analyzed for different Physico-Chemical parameters such as pH, Temperature, TDS, BOD, COD, Total Alkalinity, Chlorides. The collected waste water samples were serially diluted and pour plated on Nutrient Agar medium and incubated at 37˚c for 24 hours. Among 12 bacterial isolates, 4 isolates namely Bacillus subtilis,Bacillus cereus, Escherichia coli and Staphylococcus aureus showed high reduction in BOD&COD in selected waste water sample.The results shows that the COD is removed maximum by Bacillus cereus in textile and sugar mill waste water about 62.88% an 51.7% respectively and 74.21 % removal by Escherichia coli in municipal waste water. The maximum removal of BOD is 82.83% in municipal waste water by Bacillus subtilis. Escherichia coli and Bacillus cereus removed 80.83% and 77.77 % respectively.
