Abstract
The invention provides a biological process for reduction of chemical and biological oxygen demand of pulp and paper industrial effluent using a mixed bacterial consortium comprising of bacterial strains isolated from natural sources which is capable of reducing chemical and biological oxygen demand of pulp and paper industrial effluent to standard discharge limits.
Claims31
A synergistic bacterial consort for treatment of pulp and paper industrial wastewater, the consortium comprising three bacterial strains, Pseudomonas aeruginosa (DSMZ 03504), Bacillus megaterium (MTCC 6544) and Stenotrophomonas maltophilia (MTCC 5182).
A process for the formation of a bacterial consortium for the treatment of pulp and paper industrial wastewater, the consortium comprising three bacterial strains, Pseudomonas aeruginosa (DSNZ 03504), Bacillus megaterium (MTCC 6544) and Stenotrophomonas maltophilia (MTCC 5182), the process comprising inoculating individual bacterial isolates separately in nutrient broth, incubating the inoculates, mixing the individual cultures after colony formation, centrifuging the resultant cell suspension to form a cell pellet, washing the cell pellet and re-centrifuging to obtain a final cell pellet, and suspending the final cell pellet in phosphate buffer.
A process for the treatment of pulp and paper industrial wastewater using a bacterial consortium comprising three bacterial stains, Pseudomonas aeruginosa DSMZ 03504), Bacillus megaterium (MTCC 6544) and Stenotrophomonas maltophilia (MTCC 5182), the process comprising inoculating pulp and paper industrial wastewater with the bacterial consortium, incubating the bacterial consortium in the wastewater and measuring the COD and BOD demand of the wastewater.
