Microbial biofilms are multicellular communities where bacteria
external stresses (e.g. antibiotics), but their physical and chemical
temperature, humidity, etc.). Gaining insight on how such cues affect
the molecular structure of biofilms would greatly benefit to the
emerging field of engineered living materials. In this work, we
extracted from biofilms grown on substrates with different water
contents. Electron microscopy, FT-IR and fluorescence spectroscopy
conditions. The results show that varying the water content of the
from the biofilms and to differences in the packing, hydrophobic
character and chemical stability of the fibers. Fibers from biofilms
on higher water content substrates. Such fundamental knowledge on the
biophysical features of amyloid fibrils sheds light on the influence
of water on biofilm behavior and how the molecular structure of
biofilm matrix defines biofilm macroscopic properties. Understanding
the molecular behavior of the biofilm matrix formed in various growth
conditions may inspire future strategies to engineer biofilm-based
materials.
