Dry mesophilic fermentation of chicken manure for production of methane by repeated batch culture.
The dry fermentation of chicken manure (CM) for production of methane in mesophilic conditions at 37 degrees C was studied under laboratory conditions using a repeated batch culture system. Methane was successfully produced after an acclimation period of about 254 d. A total volume of 4.4 l kg(-1) CM (31 ml g(-1)VS) of methane gas was produced, despite the presence of a high level of ammonia of ca. 8 to 14 g-N kg(-1) CM. This clearly demonstrates that spontaneous acclimation of the methanogenic consortia to high levels of ammonia could occur and result in production of methane even under a high percentage of total solid (25%) and a high level of ammonia.
