MR14 is sensitive to SDS and EDTA. (A) Percentage of growth, determined by measuring OD₆₀₀ at 8 h in the presence of 0.01% SDS, 0.1 mM EDTA and SDS/EDTA compared with untreated samples. (B) Sensitivity of ATCC 17978, MR14 and MR14C to different concentrations of EDTA (0–1 mM). (C) Growth defect percentage as described in (A) in the presence of 0.4 mM EDTA alone. Data from n = 3 biological replicates are reported as mean ± SD. * p < 0.05, ns = not significant, *** p < 0.001 and **** p < 0.0001.
