Effect of NDGA on H₂O₂ sensitivity. (a) Representative disk assays for H₂O₂ sensitivity of ATCC700392 exposed to 50 μM NDGA. (b) The H₂O₂ sensitivity of ATCC700392 and fecA1-deletion mutant of ATCC700392 (ATCC700392ΔfecA1) under exposure to NDGA was measured by the method described under Materials and Methods. Results are means ± SD of three independent assays. ; (Tukey test).
