Chementator: A faster way to decontaminate soil
Liberty Engineering (Hamburg, N.Y.; www.libertypsa.com) has developed a bioremediation system that fully removes carcinogens from soil in 90 days. The process is based on microbial oxidation of organic compounds by petrophyllic pseudonomads in an oxygen-rich environment. The bacteria are specifically…
Chementator: Feed sugar to these bacteria and they’ll produce hydrogen
Azotobacter are nitrogen-fixing bacteria that do a useful job in soil by converting N 2 to ammonia. As a side reaction they also produce hydrogen, most of which they oxidize for their own energy consumption. In a project of the…
