Microalgae can be used to produce bioenergy in several ways. One of the most efficient ways is through the utilization of the algal oils to produce biodiesel. Microalgae are traditionally cultivated either in open ponds or enclosed systems. However, there have been limitations due to the production methods to grow and harvest microalgae. An attached microalgal growth using wild benthic microalgae in outdoor cultivation was evaluated in this study. The first part of the work evaluated the feasibility study of wild benthic microalgae onto the substrata for the attachment in natural filtered seawater. The results showed that wild benthic microalgae could produce feasible high biomass yield. The benthic microalgae of 0.87±0.05 g dcw/L were produced with crude oil and triacylglycerol content of 10.9% and 7.2% (w/w), respectively. In the second part, two-stage cultivation was carried out with nitrogen and/or salinity stress for triacylglycerol accumulation. Triacylglycerol content of microalgae increased from 7.2% to 19.3% (w/w) on 2nd day in two-stage process. This study provides the pictures of future microalgal oil production.
