Research Progress on the Production of Bioactive Compounds from Marine Diatoms

Bioactive compounds have a broad range of applications in food, feed, cosmetic, nutraceutical, and pharmaceutical industries. Thus, the studies of bioactive compounds have been gaining great attention from science and the public in recent decades. Given the advantages of fast growth, high content of bioactive compounds, easy to be cultured and scaled up, and effective biorefinery, marine diatoms were considered to be the most promising producers of natural bioactive compounds. Although a large number of studies have been carried out to enhance the production of bioactive compounds from marine diatoms, a commercial production scale has seldom been realized due to several intrinsic shortcomings such as old culture technology and high production cost. This review aims to provide an overview of bioactive compounds from marine diatoms and their high production strategies. The path forward for further commercial production of the bioactive compounds from marine diatoms with respect to 3 different opportunities is also discussed, which will in turn accelerate the development of microalgae industry and provide support for human health and high-quality life.
