Description
Summary:Scenel!esmus dimorphus, green microalgae, was grown mixotrophically in the laboratory under controlled conditions to establish baseline characteristics of cell growth and maintained in NGP (Norhadi's Growth Promoter) medium. The medium was subjected to different amount of fertilizer and growth promoter, Leaffie Organisol for the improvements of the NGP Medium. The objectives were to improve the NGP medium for outdoor mass cultures of Scenedesmus dimorphus and to measure its lipid yield. The results showed that there was an ob ious difference in the growth rate of S. dimotphus. The best improved modified culture showed highest cell density achievement at 1.56 x 10 6 cells per ml with growth rate, K'= 0.01213, d·\ The outdoor mass culture with 0.55 mL'\ growth promoter under pH 6.4 produced lipid at 0.96 % of total dry mass. Further studies on S.dimorphus need to be performed in order to further optimize the media and growth rate to achieve maximum lipid content.
