2.2.1 Specific interactions
In specific interactions, specific appendages of bacteria (bacterial
hairs, flagella, coils) can bind to some chemicals on certain surfaces[22]. For example, the characters ofPseudomonas aeruginosa , Pseudomonas putida , and E.
coli appendages contain long-chain networks of polysaccharides and
biopolymers that create spatial forces with the material surface[27], which in turn facilitate their adhesion to
the material surface.
