假单胞菌铁载体及色素研究

摘要

假单胞菌分布广泛,种类繁多,能够产生多种结构的铁载体及具有特定颜色的色素化合物,这使假单胞菌在生物病害防治、医学研究等领域应用潜力巨大.假单胞菌铁载体具有菌种和菌株特异性,可在一定程度上作为其分类依据.假单胞菌色素具有色调、结构、功能多样性,与其铁载体在功能上具有一定重叠性.假单胞菌铁载体及色素分离纯化方法相对比较简单,但它们的生物合成及转运代谢机制非常复杂.%The widely spread bacteria of Pseudomonas genus could produce siderophores with different chemical structures and pigments with special colors. These siderophores and pigments confer the Pseudomonas bacteria great practical application potency in diseases controlling and medical researches. In some content, siderophores could be used as a tool for Pseudomonas taxonomy. Pigments produced by Pseudomonas have diverse dues, chemical structures and functions, in addition, some of them also function as siderophores. It is relatively simple to isolate and purify the Pseudomonas's siderophores and pigments, while the biosynthesis and transport regulation mechanism are complicated very much.
