Time wrote about the girls: "The trio from Co Cork took home the grand prize at the Google Science Fair after wowing the judges with their discovery: Diazotroph, a bacteria that sucks nitrogen from the atmosphere into soil, speeding up the germination of cereal crops like barley and oats and - more importantly - increasing their yield.
It can be less than doubled, or it can be up to ten times more," says LaRoche, adding that such measurements depend heavily on the composition of the diazotroph community and provide only a snapshot of rates in a particular location and time.

Studies on the soil bacterium Azotobacter vinelandii indicate that it yields hydrogen as a by-product of nitrogen fixation; and its characteristics such as high respiratory rates, the ability of expressing anaerobic proteins, and lower growth requirements project the possibility of bridging the diazotroph and hydrogenase.
