Thermophilic environments are said to be good sources of new microorganisms. A bioprospecting expedition to the Icelandic hotsprings yielded some microorganisms which can produce hydrogen and ethanol (both having biofuel applications) under thermophilic conditions (50 degress Celsius to 78 degrees Celsius). The results of the findings, headed by Perttu Koskinen, of the Tampere Institute of Technology, in Iceland, are published in the ACS (American Chemical Society) journal, Energy and Fuels (URL above). Dominant bacteria from enrichment cultures were found to be “closely affiliated with Thermoanaerobacter thermohydrosulfuricus”, and produced 1.21 moles of ethanol per mole of glucose and 0.68 moles hydrogen per mole of glucose at 78 degrees Celsius. The paper concludes that the full potential for hydrogen and ethanol production of the isolated samples “have yet to be revealed”..
