Tryptone serves as a peptide-rich nitrogen and carbon source for bacterial culture, primarily targeting the regulation of bacterial surface proteins and biofilm-related gene expression. It enhances the expression and assembly of adhesion proteins, such as LapA and LapF, by supplying essential peptide substrates that increase cell surface hydrophobicity and strengthen intercellular adhesion. This stabilization of the biofilm matrix supports the maturation and maintenance of bacterial biofilms, while the peptide mixture within Tryptone can modulate the transcription of key adhesion-related genes, thereby influencing the synthesis and localization of biofilm structural proteins.
