The effects of temperature on anaerobic digestion for biogas production were investigated. The tests were carried out in self-made anaerobic fermentation devices, with cabbage leaves as raw materials. Results showed that the value of VFA, NH+4-N and pH values at mesophilic fermentation ((35±1)℃) was in normal range superior to thermophilic ((55±1)℃) and room temperature. The total yield of biogas at mesophilic fermentation was 42.5% higher than thermophilic fermentation. The CH4 content at mesophilic fermentation was 7.6% and 19.1% higher than thermophilic and room temperature fermentation, respectively. Therefore, mesophilic fermentation condition is considered suitable for biogas production from cabbage leaves.
