It was during a walk along the coast that Ravi Naidu found the answer to his problem: "Seaweed! The idea just popped up." The ubiquitous and cheap plant material held the solution to his biore-mediation experiments DDT-contaminated soils. He and colleague Mallavarapu Megharaj of the University of South Australia found that sodium enhances bacteria's ability to degrade DDT in anaerobic environments. Throwing in some organic matter as fertilizer further accelerated the process. "Seaweed contains sodium and is a source of dissolved organic carbon," explains Megharaj.
