Enzymatic activity of peroxicreted alcohol oxidase. Using 100 μl of supernatant of shakeflask grown A. niger cultures the degradation of 0.1% H₂O₂ was monitored in 2 ml milliQ by measuring absorption at 240 nm. (black triangle) represents the H₂O₂ degrading activity of 100 μl supernatant of the wild type strain, (black circle) represents the H₂O₂ degrading activity of 100 μl supernatant of the peroxicretion strain and (black square) represents the H₂O₂ degrading activity of 100 μl supernatant of the peroxicretion strain overexpressing gene ID 4990113 which shows strong similarity with several alcohol oxidases.
