The present invention relates to the cultivation of mixotrophic microalgae. More particularly, the present invention relates to a method for cultivation of mixotrophic microalgae, comprising the steps of (a) acidifying a feedstock obtained from palm oil industry using hydrolytic microorganisms, acidogenic microorganisms, and acetogenesis microorganisms under a pH environment between 4 to 5.5 in a first area and obtaining a liquid mixture comprising short-chain organic acids and minerals; (b) feeding the liquid mixture into a second area, wherein the second area comprises microalgae and has a pH environment between 5 to 7; and (c) providing circulation in the first area, second area, or a combination thereof, whereby sediments formed at the bottom is displaced in an upward manner in order to be exposed to air and light in proximity to the surface of the respective area. In the first area, the circulation allows acidification of the feedstock to proceed in a non-anaerobic condition. In the second area, the circulation allows the mixotrophic microalgae at the bottom of the second area to be exposed to air and light so as to improve cultivation efficiency while preventing formation of anaerobic pockets in the liquid mixture which favour the growth of undesirable microorganisms, such as methanogenic microorganisms.
