摘要
讨论红树林根际放线菌的数量、组成及其产生生物活性物质的规律。结果表明,放线菌的数量与海滩潮区、红树生长龄及生长密茂程度有关。高潮滩区及生长密茂的红树根际放线菌数量比中潮滩区、幼苗及生长稀疏多,红树植物及其根际与放线菌之间存在着复杂的相互作用关系。与岸边菜园上相比,虽然红树根际放线菌的数量较少,但组成却比较复杂,有6个属,链霉菌有 12个类群,并具有产生抗生素、固氮酶、几丁质酶、α-淀粉酶抑制剂、胃及胰蛋白酶抑制剂的菌株。表明红树林根际放线菌有可能成为新的有效生物活性物质的重要来源。
This paper discusses the law of the amount, composition and biological active substincs of Actinomycetes in Mangrove rhizosphere. The results show that the amount of Actinomycetes depends on intertidal area, age and flourish degree of Mangrove growth. The amount of Actinomycetes in high tide area and flourish growth is more than that in mid tide and that in the case of seeedling and rare growth. The complex interactive relationships between the Mangrove (and its rhizophere) and the Actinomycetes are suggested. Different from vegetable farmland, the amount of Actinomycetes in Mangrove rhizosphere is less but the composition is morecomplex. The Act-inomycetes includes 6 genera, in which Streptomyces has 12 groups. The strains that could produce antibiotic, nitrogenase, chitinase,α-amylase inhibitor, pepstatin, and pancreatin. inhibitor were screened. Obviously, it may turn important source in screening for the strains of new effective biological active substance.
