Intracellular bacterial macromolecules within biofilms

The term Intracellular bacterial macromolecules within biofilms refers to a broad and heterogeneous collection of biological polymers—including proteins, nucleic acids, and polysaccharides—located inside bacterial cells that are organized into a biofilm community. Biofilms are complex clusters of microorganisms embedded within a self-produced matrix of extracellular polymeric substances (EPS), which provides significant protection against environmental stressors and host immune responses (Hall & Mah, 2017, Nature Reviews Microbiology). While specific macromolecules within these cells, such as ribosomes or DNA gyrase, serve as the actual molecular targets for various antibiotics, the collective term itself does not describe a single, discrete therapeutic target. Targeting these components effectively requires drugs to first penetrate the dense EPS matrix and then cross the bacterial cell membrane, a dual challenge that often leads to high levels of antimicrobial tolerance (Donlan & Costerton, 2002, Clinical Microbiology Reviews). Consequently, this term is more descriptive of a physiological state and location rather than a specific receptor or enzyme used in drug discovery pipelines.
