Bugs in a Bottle: H2 Production by Bacteria
 Researchers
at DOE’s National Energy
Technology Laboratory successfully sustained a population of bacteria
that produces almost as much as their containment vessel’s volume, in
hydrogen, every day. Tested for over 45 days in a 10 liter bioreactor, the
bacteria,
Thermotoga neapolitana, produced an estimated 8 liters of hydrogen in 24
hours. This unusual thermophilic (heat-requiring) strain converts sugar into
hydrogen with nearly 100 percent efficiency. Tests were conducted with pure
sugar - a standard that allows comparisons to results of similar research.
However, NETL researchers have established that a wide range of sugar and
carbohydrate food sources, including organic wastes, would be practical as
feedstock. |
