DESCRIPTION:As living organisms\, bacteria exhibit motility induced phase 
 separation as well as population dynamics. A minimal stochastic model is c
 onstructed to investigate the phenomenologies and the entropy production r
 ate of such systems. Two distinct solutions are found: phase separation ar
 rested at a fixed length scale and limit cycles where the bacteria alterna
 te between the free-swimming planktonic phase and the “colony” phase. 
 Building on the deterministic solutions\, the entropy production rate can 
 be calculated to low orders in noise\, as a way of quantifying the amount 
 of time reversal symmetry breaking in the system.
