Biofilm & Chlorine Dioxide Learning Hub
A curated, evidence-led guide to biofilm structure, disinfectant tolerance and practical hygiene contexts. General published chlorine-dioxide research is not a claim about ChloroKlean products or a substitute for product labels and site-specific advice.

What Is Biofilm?
Biofilm is a surface-associated community of microorganisms embedded in a self-produced matrix. It can develop on wetted surfaces where conditions support
Read guidePlanktonic Bacteria vs Biofilm
Planktonic bacteria are suspended in liquid; biofilm-associated cells are attached to a surface and embedded in matrix. The distinction matters when interp
Read guideWhat Is EPS in Biofilm?
Extracellular polymeric substances (EPS) are matrix materials associated with biofilm communities. They can include polysaccharides, proteins, nucleic acid
Read guideChlorine Dioxide and Biofilm: What the Evidence Shows
Published studies examine chlorine dioxide against biofilms in particular laboratory and applied settings. Those findings support scientific discussion, bu
Read guideDisinfectant Residuals and Biofilm Control
A measured disinfectant residual can be a useful operational indicator, but it is not a direct measurement of biofilm or a guarantee of control.
Read guideMixed-Species Biofilms and Disinfectant Tolerance
Many operational biofilms contain more than one organism. Interactions between organisms and the surrounding matrix can complicate laboratory-to-site compa
