Fig. 1From: Bacillus pumilus KatX2 confers enhanced hydrogen peroxide resistance to a Bacillus subtilis PkatA::katX2 mutant strainGrowth of the B. subtilis katX2 mutant (diamonds) compared to the B. subtilis 168 strain (squares). Control conditions are shown with filled, stressed cultures with empty symbols. Time point of addition of H2O2 is shown by arrows. The H2O2 concentrations used were 50 µM (a), 200 µM (b) and 2 mM (c)Back to article page
