BOD beads – a ready to use seeding material for estimation of organic load of wastewater
Abstract
A reusable immobilized microbial composition is designed to estimate the biochemical oxygen demand in industrial wastewater streams. The formulated microbial composition comprises a synergistic mixture of the bacterial strains of Enterobacter cloacae (ATCC no. 29893), Citrobacter amalonaticus (ATCC no. 25406), Pseudomonas aeruginosa (ATCC no. 49622), Yersinia enterocolitica (ATCC no. 27739), Klebsiella oxytoca (ATCC no. 15764), Enterobacter sakazakii (ATCC no. 12868) and Serratia liquefaciens (ATCC no. 25641). The consortium is immobilized by using 2% sodium alginate and 0.15 M
