liquid phase photobioreactor

A typical photobioreactor is a three-phase system comprising the liquid phase (medium), the solid phase (cells), and the gas phase. Light, which is the unique feature of photoreactors and is often addressed as the fourth phase, is the main parameter affecting reactor design as it determines microalgal growth and, thus, photosynthetic efficiency.
