Comparative Studies on Simultaneous Biodegradation of Phenol and Cyanide Using Different Strains

摘要

Removal of pollutants like phenol and cyanide is a serious environmental concern. Widespread studies on the biodegradation of phenol and cyanide have been carried out to overcome the environmental problems. This study provides an overview on the biological degradation of phenol and cyanide by isolated strain S.odorifera. For comparison three strains namely, A. chroococuum, E. coli and P. putida were also used for the degradation of phenol and cyanide. In this study, the effect of initial concentration of phenol and cyanide on their removal and biomass concentration was studied. It was observed that amongst these four bacteria percentage removal of phenol and cyanide, was found to be maximum for S. odorifera. The maximum tolerance level of phenol and cyanide for S. odorifera was found to be 1500 mg/l and 150 mg/l respectively. It was also concluded from this study that, the bacteria S. odorifera was capable simultaneous removal of phenol and cyanide i.e., 88.26% and 99.85% respectively.
