  Motivated by gauge theory/string theory correspondence, a lower bound on the
bulk viscosity of strongly coupled gauge theory plasma was proposed in
arXiv:0708.3459. We consider strongly coupled N=4 supersymmetric Yang-Mills
plasma compactified on a two-manifold of constant curvature beta. We show that
the effective (1+1)-dimensional hydrodynamic description of the system is
governed by the bulk viscosity violating the bound of arXiv:0708.3459, once
beta<0.
