Biofilm structure
Ecosystems are composed of a variety of energetic microhabitats where
microbial communities interact ideally ”as metabolically interdependent
groups”. Bacteria colonise microhabitats compatible with their
physiologic and metabolic needs, which depend upon their neighbouring
bacteria, and this may influence the spatial structure of the community.
Biofilm communities are composed of either interspecies or lipids. The
extracellular polymeric substance provides protection to the
microorganism not only from altered pH, osmolarity, and nutrient
scarcity but also blocks the access of bacterial biofilm communities to
antibiotics and therefore the host’s immune cells (Sharma et al., 2019)
(Fig 1. Structure of Biofilm Formation).
