Anaerobic treatment of undiluted cow dung (15% total solids), so-called dry fermentation, produced hydrogen (743 ml-H(2)/kg-cow dung) at an optimum temperature of 60 degrees C, with butyrate and acetate formation. The hydrogen production was inhibited by the addition of NH(4)(+) in a dose-dependent manner. A bacterium with similarity to Clostridium cellulosi was detected in the fermented dung by a 16S rDNA analysis.
对未稀释的牛粪（总固体含量15%）进行厌氧处理，即所谓的干式发酵，在60℃的最佳温度下产生了氢气（743毫升-H₂/千克牛粪），同时形成了丁酸盐和乙酸盐。添加NH₄⁺会以剂量依赖的方式抑制氢气的产生。通过16S rDNA分析在发酵后的牛粪中检测到一种与纤维梭菌相似的细菌。
