To improve removal performance, Pseudomonas sp. YATO411, which is effective for biodegrading
toluene [22], was combined with Mycobacterium sp. CHXY119 in a Mycobacterium sp. CHXY119 and Pseudomonas sp. YATO411 immobilization bead for biodegrading BTEX. Fig. 3 shows the variation in
the remaining doses of B, T, E and X under different concentrations of the immobilized Mycobacterium sp. CHXY119 and Pseudomonas sp. YATO411 as a function of incubation time.
