Microalgae are highly regarded as ideal materials for the creation of liquid biofuels and have substantial potential for growth and utilization. However, traditional storage and culture methods for microalgae are plagued by challenges such as uncontrolled growth, bacterial contamination, and self-shading among algae. These issues severely impede the photosynthetic process and the efficient extraction of biomass energy. This study tackles these problems by utilizing magnetic hydrophobic protein particles to stabilize water-in-oil Pickering emulsions. This allows for the micro-compartment storage and magnetic transfer of algae. Additionally, the successful encapsulation of Chlorella cells in high-internal-phase water-in-oil Pickering emulsions effectively mitigates the settling problem of Chlorella cells in the liquid phase, thereby enabling the potential use of Pickering emulsions for the confined cultivation of microalgae.
微藻被高度视为生产液体生物燃料的理想材料，具有巨大的生长和利用潜力。然而，微藻的传统储存和培养方法面临着诸如生长不受控制、细菌污染以及藻类自身遮光等挑战。这些问题严重阻碍了光合作用过程以及生物质能的高效提取。本研究通过利用磁性疏水蛋白颗粒来稳定油包水型皮克林乳液解决了这些问题。这使得藻类能够进行微室储存和磁性转移。此外，将小球藻细胞成功封装在高内相比油包水型皮克林乳液中，有效缓解了小球藻细胞在液相中的沉降问题，从而使皮克林乳液有潜力用于微藻的受限培养。
