Fig. 2From: A novel gene from the acidophilic bacterium Leptospirillum sp. CF-1 and its role in oxidative stress and chromate toleranceROS levels of E. coli transformed with ABH19_09590 from Leptospirillum sp. CF-1. Cells were stressed with A 5 mM K2CrO4, or B 5 mM H2O2 for 30 min. Cytoplasmic ROS content is expressed as relative fluorescence units (RFU) of the activated fluorescent probe H2DCFDA per mg of proteinBack to article page
