Sentences with phrase «only nitrogenase»

They also examined data that showed that genes for iron - only nitrogenase were detected in a number of physiologically diverse microorganisms that also vary in the conditions under which they survive.

Still, the researchers did not expect that the methane they were seeking would be generated by iron - only nitrogenase in this organism.

However, although iron - only nitrogenase was identified several decades ago, scientists had not yet noticed that it, too, could be used by some microorganisms for methane production.

«There is now recent evidence that iron - only nitrogenase is active in microbes more often and in more conditions than we had previously thought,» Zheng observed.

Roughly 10 percent of these nitrogen - fixing microorganisms contain the genetic code for manufacturing a back - up enzyme, called iron iron - only nitrogenase, to do their job.

To make sure this methane - generating pathway was not exclusive to Rhodopseudomonas palustris, they tested for similar abilities in three other nitrogen - fixing bacterial species that have iron - only nitrogenase.

Not exact matches

Vanadium nitrogenase found in soil bacteria can in its natural setting perform the same synthesis that is only possible in industrial processes with the aid of extreme pressures and high temperatures.

In nature, only one enzyme — bacterial nitrogenase — can achieve the same reaction, but without emitting excess nitrogen compounds into the environment, or in other words, leaching of nitrates into groundwater.
