Embodiment 2

[0051] A sludge is obtained from a pig farm biogas in Zhejiang Province, and the separation of anaerobic sludge is finally obtained by mixing bacteria for methane.

[0052] A 1000 mL triangular bottle was taken for 30 min in a high pressure steam sterilization pot at 100 ° C. After cooled to room temperature, 300 ml of anaerobic sludge was added to the triangular bottle and stored in an environment without other fungi. Formulated liquid medium, ingredient of liquid medium: 10 g / L ammonia acetic acid, 2g / L protein, 2g / L yeast powder, 0.5 g / L cysteine, 0.4g / l K 2 HPO 4 , 0.2g / L MGCL 2 · 6h 2 O and 1L distilled water, the formulated liquid medium was sterilized under 121 ° C for 15 min, and 600 ml of liquid medium was added to 1000 ml of sterilized triangular bottle.

[0053] The above-mentioned 300 ml of anaerobic sludge was added to 600 ml of liquid medium and mixed, and the mixed uniform triangular bottle was allowed to stand for 7 days in anaerobic case, and the anaer...
