Webb30 aug. 2013 · The nitrogenase activity was assayed using the acetylene reduction assay (ARA). A 1 mL aliquot of the diazotroph culture was transferred to an airtight 30 mL bottle containing 10 ml of N -free semi-solid malate (Nfb) medium. WebbNitrogenase has the capacity to reduce certain other compounds apart from its natural substrate, dinitrogen. Reduction of acetylene by nitrogenase is very well exploited for …

WebbAnabaena sp. is a filamentous photosynthetic cyanobacterium which has potential as a source of organic matter and nitrogen fixation ability. Accordingly, the present investigation emphasizes the effect of light … WebbNitrogenase can reduce acetylene to ethylene which can be detected with great ease and sensitivity with a gas chromatograph. Almost all efforts to quantitate nitrogenase activity begin with acetylene reduction, and though there are good reasons to run parallel studies with 15 N incorporation or NH 3 synthesis, this assay remains a most powerful ...
