The present invention provides a seeding material for accurate and reproducible monitoring of BOD load of pulp and paper wastewater, wherein the bacteria are isolated from various locations in India and comprisesp.,sp.,andthe microbial composition being capable of exerting an appropriate BOD for pulp and paper industrial wastewater due to the specificity of bacterial strains present therein towards the refractory organic compounds found in these effluents.

Microbial consortium useful as seeding material for BOD analysis of pulp and paper industrial wastewater

Immobilized cell beads incorporating formulated microbial consortium comprising a synergistic mixture of the following bacterial strains namely, and selected from the following isolated bacterial strains namely, are prepared, the formulated microbial consortium is immobilized in an appropriate immobilizing agent resulting in the formation of beads and the beads are used for instant BOD estimation using an electronic device and the formulated cell beads are reusable and are capable of assimilating most of the organic matter present in varied industrial effluents.

Process for the preparation of cell beads BOD sensor useful for instant BOD estimation

An immobilized microbial consortium is formulated which comprises of a synergistic mixture of isolated bacteria namely, and The formulated microbial consortium is immobilized on charged nylon membrane. The said immobilized microbial consortium is attached to dissolved oxygen probe for the preparation of electrode assembly. The prepared electrode assembly is used for rapid and reliable BOD estimation. The prepared electrode assembly is used for monitoring of BOD load of synthetic samples such as Glucose-Glutamic acid (GGA) used as a reference standard in BOD analysis and industrial effluents; covering a range from low to high biodegradable organic matter.
