APPLICATIONOF DEFINED CO-IMMOBILIZED MICROBIAL CONSORTIUM AS A READY-TO-USE SEED INOCULUM IN BOD ANALYSIS

摘要

A number of microorganisms were isolated from sewage. Bichemical Oxygen Demand (BOD-5 day) analysis was carriekd out by individual pure cultures. The cultures giving higher or equal BOD values as compared to reference GGA solution wwere selectedf for the formulation of a defined mixed microbial consortium. This microbial consortium was co-immobilized on calcium-alginate beads. Four synthetic and six industrial samples were tested for BOD by using immobilized beads as well as sewage as source of seeding materials. BOD values obtained with beads for all the synthetic as well as industrial samples were fairly comparable with those obtained with sewage.
