摘　　要：从淀粉废水中分离获得一株光合细菌,经形态特征、培养特征、生理生化特征及G+Cmol%含量等生物学特性分析,确定为球形红杆菌(Rhodobacter sphaeroides)L_2.该菌应用于淀粉废水处理,COD去除率达95.7%;发酵产类胡萝卜素,产量达295mg/L;作为饲料添加剂进行肉鸡饲喂,增重16.40%.A strain of photosynthetic bacteria isolated from starch waste water was classified as Rhodobacter sphaeroides by morphological characters, cultural characters,physiological biochemical characters and measurement of G + Cmol%. When the strain was applied to carotenoid fermentation, starch waste water treatment and fodder additive for chicken, the amount of carotenoid reached about 295mg/l,the COD removal rate of starch waste water treatment was 95.7% and the weight of chicken was increased by 16.40%.
