Abstract
Abtract
Uptake-hydrogenase activity in the blue-green alga (cyanobacterium) Anabaena variabilis is dependent on the presence of nickel. Nickel depletion leads to an enhancement of net lightinduced hydrogen evolution, which is catalyzed by nitrogenase. Addition of nickel chloride to the culture reverses this effect by stimulating hydrogenase activity. Methylviologen/dithionitedriven hydrogen formation of permeabilized cells is decreased by nickel depletion.
