The German gas stations are forced to offer also the so-called E10 fuel in addition to normal gasoline. This containsbetween five and ten per cent bioethanol and should improve as the energy balance when refueling. Really the biofuel ispopular but not, because many motorists have fear through the admixture of harming their engine. “University of Maryland” researchers have now developed a process where one hundred percent bio-fuel is produced. With the help ofalcohol-resistant bacteria, biomass is thereby transformed into gasoline. In the long run is to transform this process energy– and cost-efficient as the biomass initially in ethanol and then mix with gasoline.
Professor Richard Kohn and Dr. Seon-Woo Kim had already developed a process in the past, to turn biomass into ethanol.Now they have modified the process thereby used slightly. In this way, the bacteria produce no ethanol more, but hexaneand octane – the two basic components of gasoline. The final conversion process it takes place in a so called fermentation broth which produced gasoline rises to the top. But so far, the procedure only in the laboratory was tested. The researchershope however more tests to increase the practicality and to be able to take then first field trials.
The potential of the newly developed procedure is doing pretty great. Because everything can be used as biomass, whatonce was a living organism. For example, organic waste left behind after harvest or the leftovers in a sawmill. Also the waste water is already used in some cities to produce energy and is potentially a source of valuable biomass. In addition to thepatent application, the researchers have published their results in the journal “Journal of Theoretical Biology”. To continue the research, however, they must acquire first additional research funds.
