一种降低堆肥过程中强力霉素浓度和耐药基因的复合菌剂及其应用
摘要：
本发明公开一种降低堆肥过程中强力霉素浓度和耐药基因的复合菌剂及其应用，属于抗生素及耐药基因去除技术领域。该复合菌剂包括苍白杆菌、伯克氏菌和假丝酵母菌，三者冻干粉的质量比为1～2：1～2：1～2。在堆肥中添加本发明的复合菌剂可高效降解畜禽粪便中残留的强力霉素，有效降解堆肥中残留的耐药基因，提高堆肥产品的安全性。接种本发明复合菌剂强力霉素降解率为46.40％，四环素类耐药基因去除率为38.71％，接种复合菌剂的堆体比未接复合菌剂的强力霉素降解效果更高、耐药基因含量更低，具有很好的应用前景。
摘要（英）：

A composite bacterium agent for reducing a doxycycline concentration and a drug-resistant gene in a composting process and applications thereof are disclosed and belong to the technical fields of antibiotics and drug-resistant gene removing. The composite bacterium agent includes Ochrobactrum sp., Burkholderia sp., and Candida sp.. The mass ratio of freeze-dried powder of the Ochrobactrum sp., theBurkholderia sp., and the Candida sp. is 1-2:1-2:1-2. Through adding the composite bacterium agent into compost, residual doxycycline in livestock excrement can be efficiently degraded, the drug-resistant gene residual in the compost is effectively degraded, and safety of a compost product is improved. Through inoculation of the composite bacterium agent, the doxycycline degradation rate is 46.40%, and the tetracycline drug-resistant gene removal rate is 38.71%. Compost inoculated with the composite bacterium agent has higher doxycycline degradation effects and a lower drug-resistant gene content than compost not inoculated with the composite bacterium agent so that the composite bacterium agent has a good application prospect.
