Microalgae are a diverse group of prokaryotic and eukaryotic photosynthetic microorganisms that grow rapidly due to simple nature. They actively produce proteins and carbohydrates in large amount over short period of time. They can be potentially employed in the production of biofuels, pharmaceutical and cosmetics. In this study, Navicula sp., a diatom strain rich in neutral lipid and EPA content, was cultivated under phototrophic cultivation system for 14 days. This study aims to compare the production of biomass, total lipid, EPA content of Navicula sp. with regards to the effect of bioturbation (i.e orbital shaking, aeration and static culture) under phototrophic cultivation. Findings showed that the highest growth rate of Navicula sp. was achieved when the cultures were maintained in orbital shaker. Biomass concentration obtained is 0.212±0.020 g L-1 followed by aeration and static cultures which were 0.197±0.042 g L-1 and 0.173±0.008 g L-1 respectively. Lipid production was the highest in aeration cultures with a total percentage of 14.54 %, followed by static and shaken cultures with the percentages of 11.21 % and 4.78 % respectively. However, the EPA content in Navicula sp. was the highest when the cultures maintain in orbital shaker with concentration of 183.66 mg L-1, whereas the aeration cultures and static cultures gave a concentration of 23.28 mg L-1 and 8.699 mg L-1 respectively. The results indicate that orbital shaking was the best cultivation method system to be adapted in order to achieve higher growth rates and EPA content in Navicula sp. [ABSTRACT FROM AUTHOR] |
