Spectroscopic measurements for release of nucleic acids upon CAP treatment.

OD medians, minima and maxima of the supernatants of untreated biofilms (UC) or biofilms treated with positive control (lysozyme treatment followed by Proteinase K digestion, (PC)) or CAP, as measured at 260 nm for release of nucleic acids. For CAP, samples were measured either 5 or 20 min after being treated with CAP for 5 or 10 min or left untreated (UC’). n = 6.
