The architecture of monospecific microalgae biofilms

Résumé

Microalgae biofilms have been proposed as an efficient alternative to suspended cultures [1]. They offer enhanced productivities and straightforward harvesting by simple scrapping. However, little is known about their structure (spatial arrangement of cells, colonies and Extracellular PolymerS; EPS), which may strongly impact bioprocess stability and productivity. For example, nutrient diffusion may decrease as a function of the cell density or colonies size and light is attenuated and may become limiting for the deeper cell layers in very thick biofilms [2]. In order to better understand the structure development in microalgae biofilms, several microalgae strains were cultivated under static and dynamic conditions (the latter to simulate conditions closer to reality) and their architecture characterized in situ using confocal laser scanning microscopy.
