Anaerobic oxidation of elemental metals coupled to methanogenesis by Methanobacterium thermoautotrophicum
Article Abstract:
The mechanisms and rates of anaerobic metal oxidation through cathodic depolarization was analyzed for a number of elemental metals. Methanobacterium thermoautotrophicum was the model organism used to study H2 utilization in the depolarization process. The metals used in the study were elemental aluminum, copper, iron, manganese, tin, zinc, cobalt, indium, magnesium, nickel and titanium. The most extensive corrosion and methanogenesis was in a sulfide-reduced, carbonate-buffered medium.

Effect of fluoroacetates on methanogenesis in samples from selected methanogenic environments
Article Abstract:
No evident toxicity or biodegradation was observed in trifluoroacetic acid (TFA) in laboratory incubations of environmental samples from four methanogenic systems, namely, the anaerobic digestor, the rumen, freshwater sediments and marine sediments. There is no toxicity evident in TFA at concentrations of up to 10 mM, as gleaned from the rate of methanogenesis. No evidence for biodegradation was also found, as there was no significant release of carbon dioxide from (1-(super 14)C)TFA.

Catalytic extraction processing: an elemental recycling technology
Article Abstract:
Catalytic extraction processing is an innovative technology for the conversion of potentially hazardous organic, organometallic, inorganic and ash waste streams into useful and marketable commercial products. It has been validated by the EPA as a technology that meets and even surpasses its waste treatment standards. The technology involves the injection of feed materials into a molten metal bath where dissociation of molecular entities to their elements and product formation occur.
