利用发光细菌检测猪肉中的兽药残留
Detection of Veterinary Drug Residues in Pork by Photobacteria

以青海弧菌Q67（ Vibrio qinghaiensis sp-Q67）和明亮发光杆菌T3（ Photobacterium phosphoreum -T3）为毒性测试发光微生物，通过测定其在不同质量浓度恩诺沙星和磺胺间甲氧嘧啶钠下的相对发光率，研究青海弧菌Q67和明亮发光杆菌T3对猪肉中恩诺沙星和磺胺间甲氧嘧啶钠的检测灵敏度。结果表明，青海弧菌Q67更适用于猪肉中磺胺间甲氧嘧啶钠和恩诺沙星的检测，最小检出率分别为0.1 和1 mg/L。
Vibrio qinghaiensis sp-Q67 and Photobacteriumphosphoreum-T3 were used as toxicity indicator strains to study their detection sensitivity on enrofloxacin and sulfamonomethoxine sodium in pork by determining the relative fluorescence ratio under different mass concentrations of enrofloxacin and sulfamonomethoxine sodium. The result showed that V.qinghaiensis sp-Q67 was more suitable for the detection of enrofloxacin and sulfamonomethoxine sodium in pork, and the minimum detection limit was 0.1 mg/L for sulfamonomethoxine sodium and 1 mg/L for enrofloxacinin.
