微藻（包括蓝绿藻或蓝藻）由于其生物量中淀粉的积累，其作为未来替代可再生能源的潜力已被积极研究。微藻中积累的淀粉可先被乳酸菌水解为有机酸，再由光合细菌通过多种途径转化为氢。本研究的目的是研究泰国本地微藻菌株的生物量生产和淀粉积累。共检出微藻25株，其中绿藻14株，蓝藻11株。其中，蓝藻菌株Nostoc sp. TISTR 8872的生物量产量最高，为0.26 g (DW)/l，而淀粉积累量最高的蓝藻菌株N. muscurum TISTR 8871的淀粉积累量高达32.97%。建议进一步研究Nostoc sp. TISTR 8872和N. muscurum TISTR 8871在不同培养基和废水中积累淀粉、蛋白质和脂肪酸的时间过程。
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.
