Biofilm structure Shear stress Surface energy] Surface pattern [cell motility Hydrodynamics and surface properties influence biofilm proliferation A biofilm is an interface-associated colloidal dispersion of bacterial cells and excreted polymers in which the microorganisms find protection from the environment. Successful colonization of a surface by a bacterial community typically means a detriment to human health or property. Insight into the biofilm life-cycle provides clues on how their proliferation can be suppressed. In this review we follow a cell through the cycle of attachment, growth, and departure from the colony. Among the abundance of factors that guide the three phases, we focus on hydrodynamics and stratum properties due to the synergistic effect they have on bacteria rejection and removal. Cell motion, regardless if facilitated by the environment via medium flow or self-actuated by use of an appendage, drastically improves the survivability of a bacterium. The growth of the colony is similarly guided by mainstream flow and the convective transport throughout the biofilm. Even after growth, hydrodynamic traction forces on a biofilm can elicit strongly non-linear viscoelastic responses from the biofilm soft matter. As the colony exhausts the means of survival at a location, a set of trigger signals activates mechanisms of bacterial release, also facilitated by fluid flow. Once in the vicinity of a stratum, a single cell is exposed to near-surface interactions, such as Van der Waals, electrostatic and specific interactions, similarly to any other colloidal particle. The success of the attachment and the potential for detachment is heavily influenced by surface properties such as the material type and topography. A review of the hydrodynamics and the surface properties provides insight into future research avenues. 102336 December 10, 2020 en http://www.sciencedirect.com/science/article/pii/S0001868620306059 2020-12-15 07:57:04 ScienceDirect Advances in Colloid and Interface Science Advances in Colloid and Interface Science DOI 10.1016/j.cis.2020.102336 ISSN 0001-8686
