Ammonium chloride (greater than or equal to 0.05 mM) effectively and reversibly inhibited
the nitrogenase activity of Azospirillum brasilense, Azospirillum lipoferum and Azospirillum …

A procedure for the immunoprecipitation of Fe protein from cell extracts was developed and
used to monitor the modification of Fe protein in vivo. The subunit pattern of the isolated Fe …

Attention is focusing on hydrogen production from wastewater, not only because hydrogen is
a clean energy but also because it can be a process for wastewater treatment. In this paper …

Nitrogenase catalyzes the conversion of dinitrogen gas (N2) and protons to ammonia and
hydrogen gas (H2). This is a catalytically difficult reaction that requires large amounts of ATP …
