ABSTRACT
Diatoms are rich sources of high-value bioactive compounds such as polysaccharides (chrysolaminarin, chitin), protein and bioactive peptides, and pigments (chlorophylls, carotenoids, marennine). These bioactive compounds have demonstrated diverse biological activities with potential applications in the food, nutraceuticals, pharmaceuticals, feed, and aquaculture sectors. This chapter provides information on the various bioactive compounds that have been discovered from diatoms including their chemical characteristics, functionality, and potential applications. The challenges and future recommendations related to the exploitation of bioactive compounds from diatoms are also discussed.
