Despite the great potential for the industrial application of microalgae, production costs are still too high to make them a competitive raw material for commodities. Therefore, studying more efficient cultivation strategies in biomass production and economic viability is necessary. In this sense, this work aimed to reduce the production costs of biomass and biomolecules using phytohormone indole-3-acetic acid in different phases of Spirulina sp. LEB 18 cultivation. The experiments were conducted on bench scale indoor for 30 days. In each couple of experiments, the phytohormone was added on different days. The supplementation of indole-3-acetic acid on half of the growth deceleration phase of the microalga showed a cost reduction of 27%, 34%, and 75% for biomass, proteins, and carbohydrates, respectively. In addition, the strategy increased the final biomass concentration and carbohydrate content at 31.2 and 33.8%, respectively, compared to the condition without phytohormone. This study is the starting point for implementing phytohormone supplementation in industrial microalgal cultures.
