Abstract (en)
[origin: WO8302952A1] A process for the growth of microorganisms wherein inorganic pyrophosphate is used as an energy source to generate adenosine triphosphate. Microorganisms with the enzymes acetate phosphotransferase and acetate kinase grow on a medium containing a fixed carbon source supplemented with inorganic pyrophosphate. This process can be used to overcome the problem of low growth or slow growth microorganisms used in commercial or industrial processes such as leaching of low grade pyrite ores, desulfurization of coal, conversion of biomass or cellulose to methanol, and conversion of biomass or cellulose to ethanol.
