Center for Culture of Marine Phytoplankton

Provasoli-Guillard中心拥有世界上最大的 海洋浮游植物的培养收集。 将培养物 分发给科学家、水产养殖孵化场、工业 公司（特别是生物技术公司）和政府 在世界各地的机构。 海洋植物学家是 海洋中的“植物”，它们构成了食物链的基础， 海洋系统。 因为海洋覆盖了地球70%的面积 浮游植物在全球生态中起着主导作用。 科学家们在实验中使用浮游植物培养物来研究 二氧化碳引起的全球变化的潜在影响 增加（温室效应）和紫外线伤害 从臭氧层空洞，以及寻找的多样性， 浮游植物生物的天然产品，可用于 治疗人类或其他疾病。 近年来， 海洋水产养殖主要是利用浮游植物 作为贝类和有鳍鱼类幼鱼食物的养殖物。 该项目将为Provasoli提供部分支持， Guillard中心的浮游植物养殖维护费用 收藏未来五年 活的浮游植物一定是 在培养中持续保持，因为没有方法 非常适合低温保存 在颁奖期间， 中心将开始对其计算机数据库进行重大修订， 并将提供对数据库的联机访问。 它还将 安装新的培养室，以实现更广泛的培养 要保持。 最后，将更换高压灭菌器， 购买用于培养基和玻璃器皿灭菌， 确保纯培养条件。

The Provasoli-Guillard Center contains the world's largest culture collection of marine phytoplankton. The cultures are distributed to scientists, aquaculture hatcheries, industrial firms (especially biotechnology companies), and governmental agencies throughout the world. Marine phytoplankters are the "plants" of the ocean and they form the base of the food chain in ocean systems. Because oceans cover over 70% of the Earth's surface, phytoplankton play a dominant role in global ecology. Scientists use cultures of phytoplankton in experiments to study the potential effects of global changes caused by carbon dioxide increases (the greenhouse effect) and of ultraviolet light damage from ozone holes, as well as searching the diversity of phytoplankton organisms for natural products that may be used to cure human or other diseases. The recent rapid expansion of marine aquaculture is largely due to the use of phytoplankton cultures as foods for larval and juvenile shellfish and finfish. This project will provide partial support for the Provasoli- Guillard Center's maintenance costs of the phytoplankton culture collection for the next five years. Living phytoplankton must be maintained continuously in culture, since no methods have been perfected for their cryopreservation. During the award period, the Center will begin a major revision of its computer database, and will provide on-line access to the database. It will also install new culture chambers to enable a wider range of cultures to be maintained. Finally, a replacement autoclave will be purchased for sterilization of media and glassware in order to insure pure culture conditions.
