The problem of a large-scale turbulent dynamo in a gyrotropic fluid is considered in the framework of the quantum-field formulation of stochastic magnetohydrodynamics. It is shown that the gyrotropy (parity nonconservation) leads to an instability which is stabilized by the spontaneous occurrence of a nonvanishing homogeneous mean magnetic field. The existence of specific long-lived perturbations of the Alfven waves in the dynamo regime is predicted, and the renormalization group and critical dimensions of all quantities are discussed.
