摘要
近年来,随着畜禽养殖业的规模化发展,畜禽粪便中残留的抗生素给生态环境和人类健康带来巨大的潜在危害。文章分析鸡粪中喹诺酮类抗生素恩诺沙星的残留量对厌氧消化特性影响,结果表明,当鸡粪中不含抗生素恩诺沙星的累计产甲烷量为240.56mL·gVS^(-1),产甲烷效果最好,对比M1-M4四组实验结果表明,M1(0mg·kg^(-1)恩诺沙星)组纤维素酶、蛋白酶、淀粉酶和脂肪酶活性均高于M2(10mg·kg^(-1)恩诺沙星)、M3(20mg·kg^(-1)恩诺沙星)和M4(40mg·kg^(-1)恩诺沙星)组,且Megasphaera和Bacteroides作为纤维素酶主要分泌菌属相对丰度较高,达到峰值为270.57U·mL^(-1),组蛋白酶、淀粉酶、脂肪酶峰值为133.82IU·L^(-1)、335.47IU·L^(-1)、470.76U·L^(-1)。
In recent years,with the large-scale development of livestock and poultry breeding industry,the residual antibiotics in livestock and poultry feces have brought great potential harm to the ecological environment and human health.This paper analyzes the influence of the residue of quinolone antibiotic enrofloxacin in chicken manure on the anaerobic digestion characteristics.The results show that when the cumulative methane production of enrofloxacin in chicken manure is 240.56 ml·gvs^(-1),the methane production effect is the best.Compared with the four groups of M1-M4,the experimental results show that M1(0 mg·kg^(-1)enrofloxacin)group has cellulase,protease.The activities of amylase and lipase were higher than those in M2(10 mg·kg^(-1)enrofloxacin),M3(20 mg·kg^(-1)enrofloxacin)and M4(40 mg·kg^(-1)enrofloxacin),and Megasphaera and Bacteroides,as the main cellulase secreting bacteria,had a high relative abundance,reaching a peak of 270.57 u·mL^(-1).The peak values of lipase were 133.82 IU·L^(-1),335.47 IU·L^(-1)and 470.76 u·L^(-1).
