Duckweed (Lemnaceae) is a fast‐growing aquatic vascular plant. It has drawn an increasing attention worldwide due to its application in value‐added nutritional products and in sewage disposal. In particular, duckweed is a promising feedstock for bioenergy production. In this review, we summarized applications of duckweed from the following four aspects. Firstly, duckweed could utilize nitrogen, phosphorus, and inorganic nutrition in wastewater and reduces water eutrophication efficiently. During these processes, microorganisms play an important role in promoting duckweed growth and improving its tolerance to stresses. We also introduced our pilot‐scale test using duckweed for wastewater treatment and biomass production simultaneously. Secondly, its capability of fast accumulation of large amounts of starch makes duckweed a promising bioenergy feedstock, catering the currently increasing demand for bioethanol production. Pretreatment conditions prior to fermentation can be optimized to improve the conversion efficiency from starch to bioethanol. Furthermore, duckweed serves as an ideal source for food supply or animal feed because the composition of amino acids in duckweed is similar to that of whey protein, which is easily digested and assimilated by human and other animals. Finally, severing as a natural plant factory, duckweed has shown great potential in the production of pharmaceuticals and dietary supplements. With the surge of omics data and the development of Clustered Regularly Interspaced Short Palindromic Repeats technology, remodeling of the metabolic pathway in duckweed for synthetic biology study will be attainable in the future.

浮萍在水生植物修复和生物产物合成中的多方面作用

浮萍（Lemnaceae）是一种快速生长的水生维管植物。由于其在增值营养产品和污水处理中的应用，它在全世界引起了越来越多的关注。特别地，浮萍是用于生物能源生产的有前途的原料。在这篇综述中，我们从以下四个方面总结了浮萍的应用。首先，浮萍可以利用废水中的氮，磷和无机营养，有效减少水体富营养化。在这些过程中，微生物在促进浮萍生长和提高其对压力的耐受性方面起着重要作用。我们还介绍了使用浮萍同时进行废水处理和生物质生产的中试规模测试。其次，其快速积累大量淀粉的能力使浮萍成为一种有前途的生物能源原料，可以满足目前对生物乙醇生产不断增长的需求。可以优化发酵前的预处理条件，以提高从淀粉到生物乙醇的转化效率。此外，浮萍可作为食物或动物饲料的理想来源，因为浮萍中的氨基酸组成与乳清蛋白相似，而乳清蛋白易于被人和其他动物消化和吸收。最后，浮萍作为天然植物工厂被切断，在药物和膳食补充剂的生产中显示出巨大的潜力。随着组学数据的激增以及簇状规则间隔的短回文重复序列技术的发展，
