摘要
以本实验室保存的8种菌株对猪粪进行处理,以氨气(NH3)和硫化氢(H2S)的去除率为除臭指标,以有效磷含量为指标判定除臭后粪肥的肥力,并对菌株2、B1和PI进行了革兰氏染色鉴定.结果表明:菌株1、2能明显抑制猪粪中NH3的产生,去除率分别为56.99%和53.31%;菌株14、B1、W-1和Dn-101能明显抑制猪粪中H2S的产生,去除率分别为81.64%、66.29%、65.66%和60.13%;菌株2、B1、PI处理后,猪粪样品有效磷含量的增加率分别为55.59%、26.82%和27.23%.
The pig feces samples were treated with 8strains which preserved in our laboratory.The removal rates of ammonia（NH3）and hydrogen sulfide（H2S）were considered as the deodorant indexes.The content of availablephosphorus was considered as the index of feces fertility after deodorization.And three strains NO.2,B1and PI were identified by the Gram stain.The results were as follows：the strains of NO.1and NO.2inhibited the releasing of NH3in the pig feces obviously,the removal rates were 56.99% and 53.31%,respectively;the strains for NO.14,B1,W-1and Dn-101inhibited the releasing of H2S in the pig feces,the removal rates were 81.64%,66.29%,65.66%and 60.13%,respectively;the strains NO.2,B1and PI increased the content of available-phosphorus,and the increasing rates were 55.59%,26.82%and 27.23%,respectively.
