  1. Well-mixed corresponds to shaken flasks and LB medium; semi-solid agar corresponds to plates with LB medium + 0.5% agar; solid agar corresponds to plates with LB medium + 1.5% agar; MHP1 corresponds to a microhabitat with no medium replacement; MHP2 corresponds to a microhabitat consisting of a linear array of 85 coupled chambers in which the left 42 chambers are connected to medium reservoir while the right 43 are not; MHP3, corresponds to a microhabitat consisting of a linear array of 85 coupled chambers in which the odd numbered patches have access to an external medium reservoir while the even numbered patches do not.
