Conversion of microalgae to biodiesel typically includes the following four steps: microalgae cultivation, cell harvesting, lipid extraction, and biodiesel conversion. A number of methods can be used to achieve lipid extraction from microalgae, including solvent extraction, cracking, supercritical extraction, pyrolysis, enzymatic hydrolysis, and osmotic shock. Many researchers have recovered microalgal lipids from dried microalgae. However, the lipid extraction from wet microalgae has to be developed because the dewatering process to obtain dried microalgae is costly. The studies on wet lipid extraction have been very limited. In this study, the feasibility of lipid extraction and biodiesel production from wet microalgae was investigated. The microalgal lipid was extracted from wet microalgae by hot-water pretreatment. To enhance the lipid extraction yield, chemicals were added to microalgal solution. The lipid extraction yields under various experimental conditions were examined. After that, the microalgal biodiesel was produced by transesterification using sulfuric acid-methanol solution. After distillation, light-yellow biodiesel was obtained from dark-green biodiesel.
