> But your quoted passage describes two non-biological detergents. So did they use a biological detergent or not? It depends on what experiment in the paper you are looking at. The supplemental section is addressing the "Laundry detergent tolerance induction assay" (a heading you can ctrl-f for) where they only used the non-biological detergent, "as biological detergent contains enzymes and other potentially disruptive components that may influence the assay". If you go to the results section you will see results for both the biological and non-biological detergent under "Decontamination efficacy of domestic laundry machines" and so on. I didn't see anything specifying what biological detergents were used.
