Microalgae most commonly used in the agricultural and food industry

Abstract

Spirulina and chlorella are among the microalgae most commonly cultivated in aquaculture as well as used in the agriculture and food industry. Both algae are characterized by a high protein content (up to 60% chlorella and up to 70% spirulina), and also contain fatty acids, vitamins, minerals and dyes. For this reason, and in connection with the current trend for healthy eating, products containing spirulina, chlorella or their extracts have become increasingly popular in recent years. These microalgae are commonly used as feed additives for various species of farm animals and in fish feeds, while their extracts are used e.g. as fertilizers in organic farming and biostimulators.
