## Abstract A tungstate‐resistant mutant of Nostoc muscorum was isolated with severely defective molybdate transport activity. It did not show nitrogenase activity or nitrate reductase activity in the presence or absence of Mo, but expressed both activities in the presence of vanadyl sulphate. V‐de
