摘　　要：[目的]了解紫金牛叶杆菌F2对吲哚醌降解的条件。[方法]研究了温度、溶解氧及不同起始浓度的底物对F2菌株降解吲哚醌的影响。[结果]此菌株能够在25～35℃条件下较快地降解吲哚醌,其中28℃条件下培养24h,对100mg/L的吲哚醌降解率为93.37%±5.78%,32h内达到完全降解;该菌为好氧菌,在溶解氧充足的条件下降解能力较强;此菌株对50～500mg/L的吲哚醌均有很好的降解效果。[结论]紫金牛叶杆菌作为一种生物治理含氮杂环化合物的新型微生物资源具有良好的应用前景。[Objective]The study aims to study the conditions for degrading isatin by Phyllobacterium myrsinacearum F2.[Method]The effects of temperature,dissolved oxygen and substrate with different initial concentration on degrading isatin by Phyllobacterium myrsinacearum F2 are investigated.[Result]F2 strain degrades isatin well under 25-35 ℃.After cultured for 24 hours under 28 ℃,F2 strain could degrade 93.37%±5.78% of 100 mg/L isatin and completely degrade it within 32 h.As the aerobic bacteria,F2 strain could enhance the degrading capability with enough oxygen and better degrade isatin with 50-500 mg/L concentrations.[Conclusion]As a new kind of microbial resources for the biological control of nitrogenous heterocyclic compounds pollution,Phyllobacterium myrsinacearum F2 has good application prospect.
