Title

Biodegradation of the octachlorocyclopentadine chlordane, by a mixed microbial mat, 1993

Abstract

A chlordane-tolerant strain of cyanobacteria was developed. The cyanobacteria was immobilized on ensiled grass clippings which provided nutrients and added a number of microaerophilic bacteria to the system. Subcultures of this Silage Microbial Mat were treated with 200 mg/1 of chlordane. Significant levels of chlordane disappearance were observed in five days. Ensiling bacteria, Chromatia, and Oscillatoria isolated from this system also demonstrated the ability to degrade chlordane. HPLC, GC/ms and an invertebrate bioassay confirms that the process was biodegradation and not bioaccumulation. This research thus provides an archetype for much needed remediation technology.
