We study the two particular models of g-essence with Yukawa-type interactions between a scalar field φ and a classical Dirac field ψ. For the homogeneous, isotropic and flat Friedmann-Robertson-Walker universe filled with the such g-essence; some exact solutions of these models are found. Moreover, we reconstruct the corresponding scalar and fermionic potentials.
