Abstract
A biofilm morphology transition is a dynamic process that mediates growth and dispersion. The development of the dynamic process shows the enhancement of the power-law tail that is observed while the biofilms grown at the air-agar interface are submerged in a medium. Environmentally driven morphology transitions of biofilm were analyzed by acquiring the phase displacements of the Doppler shift and linearly decomposed by ballistic (Cauchy) and diffusive (Gaussian) distributions. The analysis provides the internal dynamic characteristics of biofilm that pave the way between the conventional dynamic parameters and the anomalous diffusion parameters.
