A biosensor was developed for the determination of BOD value of fermentation industry effluent. e developed biosensor was fabricated by immobilizing the microbial consortium on cellulose acetate (CA) membrane in close proximity to a DO probe electrode. e microbial consortium was harvested from the fermentation industry effluent. e BOD biosensor was calibrated by using a solution containing the equivalent amount of glucose/glutamic acid (GGA) as a standard sample solution.e response time was optimized by immobilizing different concentrations of cell biomass on CAmembrane. Once the response time was optimized, it was used for determination of BOD of fermentation industry effluent. For analysis of fermentation industry effluent, the response timewas observed 7minuteswith detection limit 1mg/L.Good linear rangewithGGA standard solutionwas observed
