As living organisms, bacteria exhibit motility induced phase separation as well as population dynamics. A minimal stochastic model is constructed to investigate the phenomenologies and the entropy production rate of such systems. Two distinct solutions are found: phase separation arrested at a fixed length scale and limit cycles where the bacteria alternate 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.
