It was found that both chloroform and acetylene could effectively inhibit methanogens. Acetylene inhibited the activity of methanogens, while chloroform inhibited metabolic process of methanogenesis. A central composite design (CCD)and response surface regression analysis (RSREG)were employed to determine the optimum conditions and interaction effects of chloroform and acetylene in terms of methane and hydrogen production. Acetylene promoted the inhibition efficiency (F = 31.14; P < 0.01)more effectively than chloroform (F = 2.46; P > 0.05). In addition, a maximum hydrogen production of 1.6 ml was estimated under the optimum conditions of chloroform concentration of 6.69 mg kg-1 and acetylene concentration of 3.08 × 10-3 (v/v). Chloroform had a significant effect on enhancing the production of propionic acid and a minimum molar ratio of acetic acid to propionic acid of 0.707 was reached with the chloroform concentration of 9.24 mg kg-1 and acetylene concentration of 4.0 × 10-3 (v/v). Hence, methanogens can be inhibited while the stabilization process of solid wastes can still work well. Moreover, co-inhibition technology practice at landfills was easible and the environmental damage was negligible, according to the analysis and experimental results.14aSOLID WASTE14aMETHANOGENESIS14aBIOLOGICAL INHIBITION14aRESPONSE SURFACE12aZhao, T.12aZhang, L.12aZhao, Y.40uhttps://drive.google.com/file/d/1OXXAimd9IYKGhMNTjP-jBqVLCm4vOGUJ/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx250602s9999    xx |||||s2   |||| ||und|d
