Abstract

Microalgae (including blue-green algae or cyanobacteria) have been actively studied regarding their potential to use as a future alternative renewable energy source due to the accumulation of starch in their biomass. The starch accumulated in microalgae can be hydrolyzed to organic acids by lactic acid bacteria prior to converting to hydrogen by photosynthetic bacteria through various pathways. The aims of the current study are to investigate the biomass production and starch accumulation in native strains of microalgal strains in Thailand. A total of 25 strains of microalgae comprising 14 strains of green algae and 11 strains of cyanobacteria were determined. Among these, a cyanobacteria strain, Nostoc sp. TISTR 8872 showed the best results in respect to biomass production of 0.26 g (DW)/l, while the highest starch accumulation was obtained from a cyanobacteria strain, N. muscurum TISTR 8871 of up to 32.97% starch. It is recommended that the time course of starch, protein and fatty acid accumulation
in Nostoc sp. TISTR 8872 and N. muscurum TISTR 8871 cultivated in various kinds of media and wastewater should be further investigated.
