【摘要】 以从生物有机肥分离出的植物乳杆菌为材料进行溶解磷试验,以期获得一株有较好解磷效果的植物乳杆菌。结果表明:从郴州市同兴南生物技术有限公司生产的生物有机肥中分离出的植物乳杆菌具有较强解磷作用,在30℃下发酵培养15 d,发酵液中的可溶性磷含量高达102.56 mg/L;在20℃下发酵培养15 d,发酵液中可溶性磷含量可达到96.43 mg/L。更多还原

【Abstract】 A strain of Lactobacillus plantarum isolated from the bio-organic fertilizer (Tongxingnan Biotechnology Co.Ltd,Chenzhou) was found have a strong phosphate-solubilizing capacity.The strain was further studied by adding tricalcium phosphate to the bacterial liquid medium,and the content of soluble phosphorus in culture medium was determined by anti-colorimetry of MO-SB.The results showed that the amount of soluble phosphorus in fermentation solution reached 102.56 mg/L and 96.43 mg/L respectively after incubation at 30°C and 20 °C for each 15 days,and the pH of the culture solution decreased gradually with the increase of dissolved phosphorus.更多还原
