abstract：:The effects of nickel on the expression of hydrogenase in the hydrogen-oxidizing bacterium Alcaligenes latus were studied. In the absence of added nickel, both hydrogenase activity, measured as O2-dependent H2 uptake, and hydrogenase protein, measured in a Western immunoblot, were very low compared with the levels in ...
