Microalgae can synthesize starch with productivity higher than conventional terrestrial crops, without the need for arable land. However, little is known about processes to extract starch from microalgae. Here, a biorefinery process is described including microalgal cell disruption followed by extraction of starch and pigments with aqueous two-phase system (ATPS) using choline chloride and polypropylene glycol 400. Sonication and bead milling were compared for cell disruption rate and starch extraction efficiency.

不同细胞破碎方法和水两相体系提取微藻淀粉和色素

微藻可以合成淀粉，生产率高于常规陆生作物，无需耕地。然而，人们对从微藻中提取淀粉的过程知之甚少。在这里，描述了一种生物精炼工艺，包括微藻细胞破碎，然后使用氯化胆碱和聚丙二醇 400 用含水两相系统 (ATPS) 提取淀粉和色素。比较了超声处理和珠磨的细胞破碎率和淀粉提取效率。
