Removal of heavy metals from wastewaters using microalgae is gaining interest because microalgae also assimilate carbon, nitrogen and phosphorus. Here, we review algal metabolism and cultivation; algal biomass conversion to biodiesel, bioethanol, biohydrogen, methane, electricity and fertilizers; and removal of metals with microalgae. The mixotrophic approach enables the effective treatment of both organic and inorganic wastes in water. For cultivation, photobioreactors are found efficient due to the control of operational conditions. Bioremediation of heavy metals by physiochemical processes appears to be more efficient than algal uptake.

用于生物燃料生产和去除重金属的微藻：综述

使用微藻去除废水中的重金属引起了人们的兴趣，因为微藻也吸收碳，氮和磷。在这里，我们回顾了藻类的代谢和培养；藻类生物质转化为生物柴油，生物乙醇，生物氢，甲烷，电力和化肥；并用微藻去除金属。混合营养方法可有效处理水中的有机和无机废物。对于培养，由于操作条件的控制，发现光生物反应器是有效的。通过理化过程对重金属进行生物修复似乎比吸收藻类更有效。
