In Vitro Nitrogen Fixation by Two Actinomycete Strains Isolated from Casuarina Nodules


Acetylene reduction activity was demonstrated in pure cultures of two actinomycete strains isolated from nodules of Casuarina equisetifolia. This activity was comparable to that of free-living Rhizobium strains, but appeared to be less sensitive to pO2 and more sensitive to the presence of combined nitrogen.
