Biomass and lipid content of Scenedesmus acutus UD01 cultured in wastewater effluent
Main Article Content
Abstract
The cultivation of microalgae as an alternative energy source has increasingly become popular in various parts of the world. However, the high cost of the media used in cultivation has directly affected the manufacturing cost. In this study, we have aimed to culture Scenedesmus acutus UD01 in the effluent acquired from the biogas system of a piggery farm (BGF), the wastewater of a sugar factory (SF), and modified JM(MJM). After 7 days of cultivation under white fluorescence at room temperature, the highest growth rate was found in BGF and the second highest was recorded in MJM. In the study on the lipid contents, the results revealed that 20.09±0.18% of lipid was obtained from S. acutus UD01 cultured in SF, while 17.72±1.05% of lipid was recorded in BGF. In considering the lipid composition and the process of culturing conducted in the low-cost media, there is a desire to find an achievable economic procedure for algal biofuel production.
