EFFECT OF DINDIGUL TANNERY EFFLUENT ON THE GROWTH OF EGG PLANT SOLANUM MELONGENA (L). USING BIOREMEDIATION PROCESSM. NAZEEMA AND T. NIRMALA
Leather industry is vital for the economic status of the country. Leather industry is the major source of revenue for the millions of people in India. Similarly agriculture is also important and the irrigation with treated effluent water is the need of the hour to meet the peopleâs demand. The effluent water should be treated to remove the hazardous material and heavy metals including cadmium, lead and nickel before irrigation. Chromium reducing capability of the organism was identified based on the presence of chromium reductase gene in the organism using PCR technique. From the total organism two organisms namely Bacillus cereus and Enterobacterium kobei have the chromium reductase gene. To study the bioremediation Enterobacterium kobei was taken for further studies. The inoculum containing E. kobei was mixed with effluent water and used to water the egg plant and the physical and chemical characteristic of the plant was studied. The plant that watered with bioremediated water showed considerably reduced chromium concentration in all parts of the egg plant. The treatment of waste water should be easily affordable and safe that is highly recommended. Thus, the present study aims to explore the microorganism which are able to bioremediates the tannery effluent water and irrigates the cleaned water for agricultural purposes.
