A Taxonomic Inventory of Marine Invertebrate-associated Microbes from the Microbial Culture Collection of Harbor Branch Oceanographic Institution

joselopezpeter McCarthyJulie OlsenA博士获得了一项资助。何塞·洛佩斯、彼得·麦卡锡和朱莉·奥尔森在海港分部海洋研究所（HBOI）对HBOI微生物培养标本中包含的深水海洋微生物进行分类调查和盘点。收集的大约9000种微生物是从深海海洋无脊椎动物（主要是海绵动物）中分离出来的。该项目将结合描述和分子遗传技术对大约一半的标本进行调查，通过互联网提供这些信息，建立海港分局海洋微生物数据库（HBMMD）和专业科学出版物，并将所获得的知识应用于宿主无脊椎动物保存标本的遗传多样性检查。认为与海洋无脊椎动物相关的微生物群落会因寄主无脊椎动物种类、地理位置和水深的不同而不同。人们对海洋微生物的生物和遗传多样性知之甚少。由于与进入深水环境相关的固有困难，对深水海洋微生物的了解甚至更少。由于旅游、娱乐利用、营养超载和海洋普遍变暖，海洋生态系统面临越来越大的威胁，迫切需要研究海洋生态系统的多样性。了解仍然相对健康的海洋生态系统中生物多样性的平衡将提高我们管理和保护它们的能力，为恢复类似但不太健康的海洋系统提出可能的目标，并有助于促进对微生物生态系统的更大的全球认识。

DEB-0103668Jose LopezPeter McCarthyJulie OlsenA grant has been awarded to Drs. Jose Lopez, Peter McCarthy, and Julie Olson at Harbor Branch Oceanographic Institution (HBOI) to perform a taxonomic survey and inventory of deeper water marine microorganisms contained in HBOI's microbial culture collection. The approximately 9000 microorganisms within the collection were isolated from deep-water marine invertebrates (primarily sponges). This project will survey about half of the collection using a combination of descriptive and molecular genetic techniques, provide access to this information via the Internet, creation of a Harbor Branch Marine Microbe Database (HBMMD) and professional scientific publications, and apply the knowledge gained to examinations of the genetic diversity within preserved specimens of the host invertebrates. It is thought that the microbial communities associated with marine invertebrates will differ with the species of host invertebrate, geographic location, and water depth.Little is known about the biological and genetic diversity of marine microorganisms. Due to the inherent difficulties associated with gaining access to deep-water environments, even less is known about deeper water marine microbes. There is an urgent need to study the diversity of marine ecosystems, which are under increasing threats caused by tourism, recreational use, nutrient overload, and general ocean warming. Understanding the balance of biodiversity in marine ecosystems which are still relatively healthy will enhance our ability to manage and conserve them, suggest possible goals in the restoration of similar but less healthy marine systems, and help to foster a greater global appreciation of microbial ecosystems.
