This paper identifies and characterises a TatD-family DNase from the planarian Dugesia japonica and shows that the enzyme disrupts bacterial biofilms — the structured communities of cells held together by a self-produced matrix of DNA, proteins and polysaccharides.
Biofilms matter to us because they are the physical basis of two problems our customers pay us to solve: persistent odour (the anaerobic, sulphide-producing mats in sewers, sumps and manure handling) and fouling or friction loss in water and industrial systems. An enzyme that attacks the DNA/EPS matrix attacks the structure that lets a biofilm persist.
Why this research is on our site
We present this work as foundational research. It is not a product datasheet and it is not a clinical claim. What it gives our product development is a mechanistic anchor: when we formulate an enzymatic or biological deodorising or cleaning line, biofilm-matrix disruption is one of the routes we can deliberately target, and this study is part of the evidence base for doing so responsibly.

If biofilm or odour is limiting a process you run, we can review the data with you and propose a biological or enzymatic programme.
