M. SAJJAD MIRZA , ASHRAF H. CHAUDHARY AND  A.D.L. AKKERMANS
Abstract
Nitrogen fixing root nodules of coriaria nepalensis consumed hydrogen pn incubation with a gas mixture containing hydrogen , indicating an uptake hydrogenase activity . the H2 uptake  by the  excised nodules varied  throughout the year  and was highest (2.16 mole H2 consumed g fresh  nodule wt-1 .hr-1.) in may. The enzyme activity was detected in vesicle cluster suspensions of the
endophyte (20 um residue) as well as in
the 20 m filterate fraction of the nodule homogenate.
