Mesophilic Methane fermentation of apple pomace was tested in laboratory scale (volume 1.8L) fermenter stirred with impeller. Seed sludge was obtained from sewage sludge treatment plant of Nagano-city, and apple pomace was gained by apple-juice production. The experiment was conducted at a temperature of 37 ℃ , and apple pomace (50,100,150,200g-wet) was added sequentially when substrate consumed entirely. When adding weight was 200g-wet, irreversible influence of methanogenesis by decreasing of pH was observed. Methane yield of apple pomace was estimated 243-292 mL-CH4/g-VS in these conditions.
