Abstract

This paper reports the effectiveness of un-acclimatized bovine rectal bacteria (BRB) in eliminating COD fro m chicken-processing wastewater. The results of shake flask experiments using 1d digestion period suggest the ruminant microbes have the potential to sequester 21% COD for an initial COD/SO4 ratio of 7.8 using the mechanis m affiliated to aerobic heterotrophic o xidation. So me 60% removal of lignin/tannin was observed although the microbes appeared adamant not to remove colour. Based on the substrate consumption of 250mg COD per litre per day, the specific microbial growth rate was estimated to be 0.40 per day; specific substrate utilization rate 1.2g COD per g cells per day; net yield 0.42g cells per g COD; and specific cells growth less than 50% per day.
