AN APPARATUS FOR MASS CULTIVATION OF MICRO ALGAE AND A METHOD FOR CULTIVATING THE SAME

摘要

An apparatus for cultivating photosynthetic microorganisms comprising a culture tank (51) containing the microorganisms grown in a culture broth fed with carbon sources and nutrients via one or more inlets (60, 61, 62); and one or more circulating means (54, 55, 56) located in the tank (51) for projecting the broth vertically from the bottom of the tank (51 ) up to the surface of the tank (51) and circulating the broth downwards to allow momentary exposure of the microorganisms to light; wherein the operation of the inlet (60, 61, 62) and the circulating means (54, 55, 56) is regulated according to a selected cultivation mode.
