Microalgae biomass is considered as a sustainable feed for the production of high-value compounds such as enzymatic and non-enzymatic antioxidants that are widely used in food, pharmaceutical, textile, leather as well as in the chemical industry. Increasing the yield of microalgae, achieving optimal culture conditions, optimal storage of antioxidant molecules after processing, and downstream processing with energy-saving are among the main obstacles to the production of antioxidants. Today, antioxidant compounds produced by microalgae as a result of stressful conditions, as important products in the field of human health, have received commercial attention. Oxidative stress due to acidity, metals, UV, and temperature can cause the production of antioxidants in many different species of microalgae such as Dunaliella algae. Dunaliella algae cultivation has several advantages, including high growth rate, low production cost, as well as the ability to grow in stressful conditions such as high salt concentrations, high light intensity, and nitrogen restriction. This article provides an overview of the production of antioxidants in the Dunaliella microalgae cellular metabolism, the activity of antioxidant enzymes (POD, SOD, CAT), and strategies to increase antioxidant accumulation in microalgae.
