Abstract
A reusable immobilized microbial composition is formulated. The formulated microbial composition comprises a synergistic mixture of the bacterial strains of Enterobacter cloaca, Citrobacter amalonaticus, Pseudomonas aeruginosa,Yersinia enterocolitica, Klebsiella oxytoca, Enterobacter sakazaki and Serratia liquefaciens. The formulated microbial composition is immobilized on an appropriate immobilizing agent to form beads. The said beads are tested as microbial seeding material for BOD analysis using Glucose Glutamic Acid (GGA) as a reference standard. The obtained BOD values by the formulated beads are compared with BOD values obtained by sewage as seeding material using synthetic samples as well as industrial effluents. The formulated microbial beads are ready-to-use as well as reusable seeding material in BOD analysis. The said beads can be reused up to five times with same efficacy.
