Research Progress on Attached Culture Technology of Microalgae

Abstract

In order to solve the problem of microalgae biomass harvesting in suspension systems, attached culture systems were proposed. In this system, microalgae are fixed on the surface or inner layer of the carrier and grow in an aggregated form. Compared with suspension culture, attached culture has higher microalgae biomass density and easier dehydration and harvesting processes. The biomass can be harvested by simply separating the carrier containing microalgae from the culture medium.
