Microalgae started receiving attention as producers of third generation of biofuel, but they are rich in many bioactive compounds. Indeed, they produce many molecules endowed with benefic effects on human health which are highly requested in the market. Thus, it would be important to fractionate algal biomass into its several high-value compounds: this represents the basis of the microalgal biorefinery approach. Usually, conventional extraction methods have been used to extract a single class of molecules, with many side effects on the environment and on human health. The development of a green downstream platform could help in obtaining different class of molecules with high purity along with low environmental impact. This review is focused on technical advances that have been performed, from classic methods to the newest and green ones. Indeed, it is fundamental to set up new procedures that do not affect the biological activity of the extracted molecules. A comparative analysis has been performed among the conventional methods and the new extraction techniques, i.e., switchable solvents and microwave-assisted and compressed fluid extractions.

从经典的微藻学习中寻求绿色提取方法。

微藻作为第三代生物燃料的生产商开始受到关注,但它们富含许多生物活性化合物。实际上,它们产生了许多对人类健康有益的分子,这在市场上是非常需要的。因此,将藻类生物质分离成几种高价值的化合物非常重要:这代表了微藻生物精炼方法的基础。通常,常规提取方法已用于提取一类分子,对环境和人体健康具有许多副作用。绿色下游平台的开发可以帮助获得具有高纯度和低环境影响的不同类别的分子。这篇综述着重于已实现的技术进步,从经典方法到最新的绿色方法。确实,建立不影响所提取分子生物学活性的新程序至关重要。在传统方法和新提取技术(即可转换溶剂以及微波辅助和压缩流体提取)之间进行了比较分析。
