SGER: Preserving a national resource- the biotic diversity in the University of Miami marine yeast collection

迈阿密大学拥有世界上最大的海洋酵母菌收藏(约2500个污渍)。酵母菌在微生物食品循环中具有重要的生态意义，因为它能将有机物质转化为可食用的微生物蛋白。作为每年800亿美元的工业基础，酵母在经济上也具有重要意义。已知的酵母菌在系统发育上是多样的，包括大约20目120属1200种，然而在自然界中只有1%的酵母菌被发现。UM收集的起源是独一无二的，该收集被国际公认为为现代分子系统学提供了基础。收藏的很大一部分仍未被研究，包含未描述的酵母菌菌株、种类和属。整个收集是未来学术研究和工业/临床开发的重要种质来源。这些收藏品面临着丢失的危险。这项SGER资金申请将暂时支持将菌株和相关的生态、表型和分子数据转移到两个最著名的国家和国际收藏馆所需的人员。已经与伊利诺伊州的NRRL/USDA Peoria和荷兰乌得勒支的中央文物局Voor Schimmel文化中心做出安排，以维护这些藏品。这两个机构将为科学界、工业界和医学界提供获得菌株和数据的途径。这些收藏品在收集和广泛研究方面投入了大量时间，这些研究产生了重大的科学贡献，而这反过来又催生了国际社会的二次出版调查。因此，必须保存这些收藏品；丢弃这些收藏品并不符合科学的最佳利益。该项目的一个更广泛的影响是保存这种独特的材料，它对科学界具有广泛的兴趣和潜在的重要性。

The University of Miami maintains the world's largest collection (~2500 stains) of marine yeasts. Yeasts are ecologically important in the microbial food loop as converters of organic material to edible microbial protein and they are economically important as the basis of 80bn dollar/yr industries. The yeasts, which are known, are phylogenetically diverse encompassing approximately 20 Orders, 120 Genera and 1200 species, however only ~1% of the yeasts in nature have been discovered. The UM collection is unique in its origin and the collection is internationally recognized as having provided a basis for modern molecular systematics. A significant portion of the collection remains unstudied and contains undescribed strains, species and genera of yeasts. The collection in its entirety represents an important source of germplasm for future academic investigations and industrial/clinical exploitation. The collection is in imminent danger of being lost. This SGER funding request will temporarily support personnel needed to transfer the strains and the associated ecological, phenotypic and molecular data to the two most prominent national and international collections. Arrangements have been made with NRRL/USDA Peoria, Ill and the Centraalbureau voor Schimmelcultures, Utrecht, The Netherlands to maintain the collection. The two institutions would provide the scientific, industrial and medical communities with access to the strains and data. The collection represents a large investment in ship time for collections and for the extensive research that has resulted in significant scientific contributions, which, in turn, have spawned secondary published investigations by the international community. Consequently, the collection must be preserved; discarding the collection is not in the best interest of science. A broader impact of this project is the preservation of this unique material that is of wide interest and potential importance to the scientific community.
