title: [Basic examination on the energization of experimental animal feces by methane fermentation (author's transl)].
abstract: Basic experiments of methane fermentation of livestock excreta have been reported by many investigators, yet there has been no report of experiments of methane fermentation of experimental animal feces. We considered that it would be feasible to gasiby experimental animal feces by methane fermentation. In this report, methane gas fermentation of rat feces is studied. The results are summarized as follows: 1. Methane fermentation of rat feces yielded, under the conditions described, 220-4231 of gas per kg of organic matter. 2. Decomposition ratio of BOD removal volume in organic matter was 50-60% when the fermentation condition was optimum. 3. The volume of gas from BOD removal volume in organic matter was 500-600ml/g. 4 Methane gas contents in the gas generated from the feces ranged from about 55-60%. 5. COD removal ratio was above 80%, and BOD removal ratio above 90%. From these data, the authors conclude that under the optimum conditions, described sufficient methane gas can be obtained from rat feces by methane fermentation.
