What Are Biofilms?
IUPAC definition (2012) : „Aggregate of microorganisms in which cells that are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS) adhere to each other and/or to a surface.
Note 1: A biofilm is a fixed system that can be adapted internally to environmental conditions by its inhabitants.
Note 2: The self-produced matrix of EPS, which is also referred to as slime, is a polymeric conglomeration generally composed of extracellular biopolymers in various structural forms.“
