Abstract：In order to study the degradation effect of the aerobic methane oxidizing bacteria on the methane in air flow, a kind of aerobic methane oxidizing bacteria which can utilize the methane as the sole carbon source was separated and purified, and an experimental device for simulating the degradation of the methane in air flow in the mine roadway was designed, which realized the regulation and control of different methane concentration, different air quantity and different bacterial solution volume. The experimental results showed that under the conditions of keeping the air quantity of 200 mL/min and the bacterial solution volume of 200 mL, the higher the concentration of methane, the more beneficial to the degradation of the methane;under the conditions of the bacterial solution volume of 200 mL, the methane concentration of 50% and the air quantity reduction from 400 mL/min to 200 mL/min, the minimum methane concentration decreased from 42% to 33%;and under the conditions of keeping the air quantity of 200 mL/min and the methane concentration of 30%, the more the bacterial solution volume, the more beneficial to the degradation of the methane.
