摘　　要：胞苷酸生产废水具有酸性强、有机物含量高、生物降解难等特点。本试验从胞苷酸生产废水中原位筛选一株特种微生物,经鉴定为绿脓杆菌(Pseudomonas sp.),研究其最佳生长条件。结果表明,绿脓杆菌最适宜的生长条件是pH值为7、生长温度为30℃、振荡培养箱转速为0r/min。在最佳生长条件下探讨菌株投加量对胞苷酸生产废水的影响,绿脓杆菌菌液投加量为100%(v/v)时,反应72h,化学需氧量(ChemicalOxygenDemand,COD)降解率最高,为45.3%。Cytidylic acid production wastewater is characterised by strong acidity,high organic content and difficult biodegradation.In this experiment,a strain of special microorganisms,identified as Pseudomonas sp.,was screened in situ from cytidylic acid production wastewater,and the optimal growth conditions were investigated,and the results showed that the optimal growth conditions for Pseudomonas sp.were pH 7,growth temperature 30℃,and shaking table speed 0 r/min;the effect of bacterial spiking on cytidylic acid production wastewater was investigated under the optimal growth conditions.Under the optimal growth conditions,the effect of bacterial dosage on cytidylic acid production wastewater was investigated,and the results showed that the degradation rate of chemical oxygen demand(COD)reached the highest of 45.3%in 72 h of reaction when the dosage of Pseudomonas sp.bacterial solution was 100%(v/v).
