| 摘 要： | 文章以枯草芽孢杆菌、巨大芽孢杆菌等10株细菌为出发菌株,以耐高温、生长速度快、生物安全性、生物拮抗性以及产酶能力为筛选原则,从中筛选得到4株细菌,分别为:地衣芽孢杆菌(Bacillus licheniformis,TKFW1003)、巨大芽孢杆菌(Bacillus megaterium,TKFW1005)、纳豆芽孢杆菌(Bacillus natto,TKFW1102)、枯草芽孢杆菌(Bacillus subtilis,TKFW1108)。然后将筛选得到的4株细菌按10%的比例添加到30 L固态发酵罐中,再添加10%的麸皮和50%的水为辅料,对餐厨垃圾进行固态发酵处理。最后将固态发酵结束后得到的产品取出烘干粉碎,经检测:经好氧微生物处理后得到的产品,其有效活菌数、有机质含量、水分含量及蛔虫卵死亡率等指标均达到了农业部农用有机肥标准,此法实现了餐厨垃圾的无害化、资源化、减量化处理,具有生产成本低、无二次污染、可操作性强等优点。 |

| Abstract: | Bacillus licheniformis TKFW1003,Bacillus megaterium TKFW1005,Bacillus natto TKFW1102 and Bacillus subtilis TKFW1005 were screened with the purpose of cultivating excellent fermentation strains with the characteristics of high-temperature-resistance,high growth rate,good bio-safety and bio-antagonistic characters as well as a strong enzyme production capacity.Solid-state fermentation of kitchen waste was conducted with the four screened aerobic fermentation strains,and the product obtained was dried and crushed and undergone examination.The result showed that several indexes could meet the requirements of relevant standard regarding organic fertilizer issued by the Ministry of Agriculture with respect to effective visible cells,content of organic matter and moister,as well as the mortality of ascaris lumbricoides eggs. |
