Abstract: | "Microbial abatement of toluene using Aspergillus niger in coir packed upflow bioreactor was investigated in this study. Toluene degrading microbes were isolated from municipal sewage effluent and identified by 16s rRNA sequencing method. The microbes were cultured in 2% (v/v) toluene input per day, which exhibited 95% removal efficiency with the kinetic correction value (R(2)) of 0.9024 at the optimum flow rate of about 0.4m(3)h(-1). Various parameters such as effect of flow rate, column height, elimination capacity and EBRT with removal efficiency for 50 day cycle were also optimized. The plug flow model for toluene degradation was properly expressed and the Monod kinetics constant K(m) and r(max) values were determined as 2.25gm(-3) and 67.773gm(-3)h(-1) respectively for microbial growth rate" |
