Abstract
We present the first study of irreversibility of bacterial turbulence, an exciting new field. We use Lagrangian statistics to show that irreversibility in bacterial turbulence leads, on average, to particles gaining energy faster than they lose it, the exact opposite of what occurs in fluid turbulence.
