Experimental Study on Biogas Fermentation of the Ginkgo biloba Leaf

Objective ] The research aimed to study biogas production potential of the G. biloba leaf. Method] G. biloba leaf as material, batch thermostatic methane fermentation test was conducted at 30 ℃ to study its biogas production potential and rule. Result] G. biloba leaf had good biogas production potential, and biogas fermentation time was 45 d. Total biogas production was 1 945 mt, and biogas production per gram of G. biloba leaf was 231 ml. Gas production rate of the TS for material was 374 ml/g （ TS）, and gas production rate of the VS was 453 ml/g （VS）. Conclusion] The research could provide reference for application of G. biloba leaf producing blogas.
