Abstract
Extracting value-added products from microorganisms is an important research focus for the future. Among the many extraction methods, ultrasound-assisted extraction (UAE) has attracted more attention owing to its advantages in reducing working time, increasing yield, and improving the quality of the extract. This review summarizes the use of UAE value-added products from microorganisms, with the main extracted substances are pigments, lipids, polysaccharides, and proteins. In addition, this work also summarizes the mechanism of UAE and highlights the factors that affect UAE operation, such as ultrasonic power intensity or power density, operation mode, and energy consumption, which need to be considered. All extraction products from microorganisms showed that UAE can effectively improve the extraction yields of value-added products. It also highlights the existing problems of the technology and possible future prospects. In general, the UAE of value-added substances from microorganisms is feasible and has the potential for development.
