The non-heterocystous filamentous blue-green alga, Plectonema boryanum strain 594 reduces acetylene to ethylene, incorporates 15N2 into cell protoplasm, and grows readily in medium free of combined nitrogen, when incubated in a gas phase without added oxygen. Cells grown in the presence of 50 mg/l of ammonium-nitrogen do not reduce acetylene, and a concentration of 0.015 atm. CO in the gas phase inhibits nitrogenase activity completely but inhibits 14CO2 incorporation by only 28%. Nitrogenase… CONTINUE READING
