Abstract
We show in this Comment that in an anisotropic Bianchi type-I model of the Kasner form, it is not possible to describe the growth of entropy, if we wa nt to keep the thermodynamics together with the dominant energy conditions. This consequence disagrees with the results obtained by Brevik and Petters en [Phys. Rev. D 56, 3322 (1997)].
