We study how this phenomenon depends on system size in bacterial
suspensions using bulk rheometry and particle-tracking rheoimaging.
Above the critical bacterial volume fraction needed to decrease
the viscosity to zero, c 0.75%, large-scale collective motion
emerges in the quiescent state and the flow becomes non-linear. We
confirm a theoretical prediction that such instability should be suppressed
by confinement. Our results also show that a recent application
of active liquid crystal theory to such systems is untenable.
