Abstract

Skeletonema sp. is a marine microalgae widely studied for its potentials as a raw material for biodiesel due to fast growth, high lipid content and resistant to environmental changes. The aim of this study was to determine the specific growth rate, biomass production, lipid content and lipid productivity of a newly isolated marine microalga Skeletonema sp. mass cultivated in 1 m 2 outdoor raceway pond. This study was conducted from June - December 2019 in the hatchery of Unit PelaksanaTeknis Daerah (UPTD) Purirono Kendari. The alga species was cultivated in 1m2 raceway pond in outdoors for a month. The alga was cultured using f/2 medium under semi-continuous mode with harvesting time every 4 days. Sampling for cell counting was done every two days whereas sampling for biomass and lipid was conducted prior to harvesting (every 4 days). The results showed that the Skeletonema sp. can grow well in outdoor raceway ponds with an average specific growth rate of 0.30 d-1, biomass yield of 0.62 g.L-1, biomass productivity of 0.222 g.L-1d-1, lipid yield of 0.28 g.L-1, lipid content of 44.81%, and lipid productivity of 0.092 g.L-1.d-1. This study showed that the Skeletonema sp. has the potential to be developed as a raw material for biodiesel due to its high growth rate, biomass and lipid productivity when mass cultured in outdoors.
