2.2 Near-interface motility behavior of bacteria
The initial aggregation of individual free bacteria and then biofilm
formation is a complex and variable process influenced by several
factors, such as the microbial species, the surface to which they are
attached, and the surrounding environment [12].
Straub et al. [10] found that the interactions
associated with bacterial adhesion can be classified into three types:
(1) Specific interactions, (2) Non-specific physicochemical
interactions, and (3) Surface mechanical sensing. This is shown in
Figure 3 [10].
