Mutant Strains for Biodegradation of PCBs in Bioreactor System
The desirable physical and chemical properties of polychlorinated biphenyls (PCBs) allowed their widespread use in industry. During the past 45 years, the total world production of PCBs has exceeded one million tons, approximately 40% of which was released into waterways. This investigation was conducted to develop microbial systems able to resist high levels of PCB (1248 and 1254) and to use these compounds as a sole source of carbon and energy. We also examined the rate of Carbon-14-PCB (C-14-PCB) uptake and its fate in bacterial cells as well as its removal from waste using activated charcoal (AC).
