    Abstract:
    This comment is devoted to the recalculation of the Casimir energy of a
    massless scalar field in the Kerr black hole surrounded by quintessence
    derived in [B. Toshmatov, Z. Stuchlík and B. Ahmedov, Eur. Phys. J. Plus
    132, 98 (2017)] and its comparison with the results recently obtained in
    [V. B. Bezerra, M. S. Cunha, L. F. F. Freitas and C. R. Muniz, Mod.
    Phys. Lett. A 32, 1750005 (2017)] in the spacetime [S. G. Ghosh, Eur.
    Phys. J. C 76, 222 (2016)]. We have shown that in the more realistic
    spacetime which does not have the failures illustrated here, the Casimir
    energy is significantly bigger than that derived in [V. B. Bezerra, M.
    S. Cunha, L. F. F. Freitas and C. R. Muniz, Mod. Phys. Lett. A 32,
    1750005 (2017)], and the difference becomes crucial especially in the
    regions of near horizons of the spacetime.
