  Saturated small-scale dynamo solutions driven by isotropic non-helical
turbulence are presented at low magnetic Prandtl numbers Pm down to 0.01. For
Pm < 0.1, most of the energy is dissipated via Joule heat and, in agreement
with earlier results for helical large-scale dynamos, kinetic energy
dissipation is shown to diminish proportional to Pm^{1/2} down to values of
0.1. In agreement with earlier work, there is, in addition to a short Golitsyn
k^{-11/3} spectrum near the resistive scale also some evidence for a short
k^{-1} spectrum on larger scales. The rms magnetic field strength of the
small-scale dynamo is found to depend only weakly on the value of Pm and
decreases by about a factor of 2 as Pm is decreased from 1 to 0.01. The
possibility of dynamo action at Pm=0.1 in the nonlinear regime is argued to be
a consequence of a suppression of the bottleneck seen in the kinetic energy
spectrum in the absence of a dynamo and, more generally, a suppression of
kinetic energy near the dissipation wavenumber.
