| 摘 要： | 本文报道微生物铁载体定性与定量测定的方法，以及小麦根圈细菌铁载体的室内检测结果。２２株小麦根圈耐寒细菌和２株固氮菌在定性检测平板上产生铁载体，另有３株固氮菌不产。定量测定结果表明：３６株水溶性色素产生菌合成铁载体的量在０．７１５－０．１０６（Ａ／Ａｒ）之间，其中属于荧光假单胞菌群的２５个菌株铁载体产量的测定值（Ａ／Ａｒ）在０．１８４－０．１０６之间，达极高量水平。

| Abstract: | An analytical method for detecting and determhining microbial siderophoresqualitatively and quantitatively was reported.The assay results showed that 22 strains ofPsychrotrophic bacteria and 2 strains of N_2-fixing bacteria isolated from wheat rhizosphere canproduce siderophores qualitatively , but the other 3 strains of N_2-fixing bacteria were negative.Itwas measured by quantitative assay that the A/Ar ratios of the siderophores produced by all of 36strains of water-soluble pigment yielding bacteria are between 0. 715-0. 106 , and 25 strains ofFluorescent Pseudomonads can synthesis siderophores as high as maxium amounts ( A/Ar=0.1840-0.106). |
