Botryococcus braunii, green microalgae, is characterized by its considerable hydrocarbon production. However, established extraction methods for hydrocarbons are limited due to low efficiency and laborious culture. This study presents solvent recycling as an extraction method to improve hydrocarbon recovery yield as well as biomass production of B. braunii. A photobioreactor was designed to operate the solvent recycling extraction process. Hydrocarbon recovery yield using this method was 2.5-fold higher than the existing two-phase extraction with high amount biomass 3.5g/L. Three-times of recycling process revealed high efficiency for hydrocarbon from B. braunii without cell loss. The method herein also successfully reduced clump formation and moreover, could be used to regenerate algal cells after three cycles of the extraction process. Accordingly, solvent recycling could recover the hydrocarbons without serious cell damage by an upstream solvent.
