Abstract

Hexanitrohexaazaisowurtzitane (CL-20), the most powerful chemical explosive known, is not degraded by activated sludge. However, alkaline hydrolysis coupled with aerobic microbial treatment is a viable option for CL-20 removal from waste streams. Furthermore, the white rot fungus Phanerochaete chrysosporium degrades CL-20 in the presence of supplementary carbon and nitrogen at CL-20 concentrations of up to 100 mg/l, with fungal growth not affected at CL-20 concentrations of up to 500 mg/l. A logistic kinetic growth model fits CL-20 biodegradation data very well. Three main possible pathways for CL-20 biodegradation are possible, all leading to similar end-products.
