The dye-oxidized or dithionite-reduced forms of the MoFe protein of molybdenum nitrogenase of Azotobacter chroococcum were shown to bind 2 mol of MgADP/mol of protein, as determined by column equilibrium techniques. The gel-filtration elution profile of unbound Mg[14C]ADP was not symmetrical, consistent with a low rate of dissociation from the protein. Symmetrical elution profiles were observed...

Azotobacter chroococcum is a bacterium known to break the triple bond that forms N2. This is important for life that cannot devour other organisms that have already converted the N2 into usable forms. Nitrogen fixing bacteria break the triple bond and form compounds that plants and other bacteria can readily use. This same species of bacteria can also break the triple bond that appears in the c...

Purpose. To investigate effects of biologicals on disease-induced damage to white cabbage plants during the growing period and yield. Methods. Informational/analytical (collection review publications), field research (planning conducting experiments, records plant damage, harvesting accounting yields), phytopathological (isolation identification pathogens), mathematical/statistical (processing ...
