Table 1 Possible reactions that can take place during TNT transformation in the presence of Y. lipolytica AN-L15 and Fe(III) minerals

From: Fe(III) mineral reduction followed by partial dissolution and reactive oxygen species generation during 2,4,6-trinitrotoluene transformation by the aerobic yeast Yarrowia lipolytica
