Abstract
We investigate the spreading of the bacterial colony on a hard agar plate in nutrient-rich conditions for different temperatures. For all the temperatures, we find the colony spreads radially outwards. Using the growth rates obtained from well-mixed culture experiments and assuming the Fisher model estimate for the spreading speed, we conclude that the colony diffusivity is also temperature dependent.
