Dioxins such as polychlorinated dibenzo-p-dioxins (PCDDs) are among the most toxic and carcinogenic environmental pollutants that can enter the food chain. There are currently few methods available to detoxify these chemicals, but one of the most promising is the use of microbial dioxin respiration pathways. In the January 23 Nature, Michael Bunge and colleagues at the Martin-Luther-Universität Halle-Wittenberg, Germany, describe an anaerobic bacterium capable of detoxification through reductive dehalogenation of chlorinated dioxins (Nature, 421:357-360, January 23, 2003).
