# bacteria.sub --
#     A basic set-up to model Ecoli bacteria in fresh and saline water.
#     Bacteria are represented by the substance Ecoli.
#
#     Important input:
#     - The irradiation (light intensity), mean over the day
#
#     Inputs of secondary importance:
#     - Salinity (actually modelled as a substance)
#     - Ambient temperature
#     - Day length (depends on the season and the location on Earth)
