    天然产物是药物的重要来源。海洋具有高压、低温、高盐度等极端环境,生活在其中的海洋放线菌已发展出独特的代谢方式,这不仅确保其在极端环境中生存,也提供了产生新颖次级代谢产物的潜力。现已从专性海洋放线菌中分到了很多结构新颖、生物活性广泛的新化合物,为新药物的发现提供了宝贵的先导化合物资源。 本论文从采集自台湾海峡的海洋沉积物中分离、筛选专性海洋放线菌以及具有生物活性的海洋放线菌,并对专性海洋放线菌的次级代谢产物进行初步研究,旨在发掘海洋放线菌资源及先导药物,为创制新型微生物药物奠定基础。 采用选择性分离方法,从9份海洋沉积物中分离到243株海洋放线菌,其中小单孢菌样215株,占88.5%。对45...The nature products were the important source of the medicine. As marine environmental with high-pressure、low temperature、high salinity,marine actinomycetes have developed unique metabolic way, it is not only ensure its survival in extreme environments, but also provides the potential to produce novel antibiotics. From the seconday metabolites of the obligate marine actinomycetes (such as Salinisp...学位:理学硕士院系专业:生命科学学院生物学系_微生物学学号:2172008115253
