| Summary: | 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. |
