Standard Operating Procedure for Microalgae Cultivation, Harvesting and Biomass Processing

A standard operating procedure (SOP) for the cultivation, harvesting, and processing of microalgae biomass is presented. The aim of this SOP is to optimize biomass produc-tion in the laboratory while preserving valuable bioactive compounds through precise con-trol of growth conditions and efficient harvesting techniques. Microalgae are increas-ingly recognized as a valuable source of bioactive compounds, including compounds with potential for agricultural, pharmaceutical, and environmental applications thus contributing to bioeconomy development. By following the outlined steps, high bio-mass yield and quality can be achieved. High biomass quality ensures that all active compounds are contained in the sample and are stable for various further treatments and chemical analyses such as for the determination of phytohormones or antimicrobial compounds when stored properly.
