通过对蓝藻、绿藻、隐藻三大门类的某些种的富集金模拟实验，确证了藻类富集金的普遍性．将藻类细胞的细胞壁（细胞膜）及一些细胞质膜从细胞中分离、提取出来，并测定了壁（膜）中金的含量；通过与整个细胞的金含量之间的对比，提出了在藻体中主要富集部位为细胞壁（膜）及一些质膜上 Through the enrichment gold simulation experiments on some species of cyanobacteria, green algae and cryptophyceae, the universality of algae-enriched gold was confirmed. The cell wall (cell membrane) and some cytoplasmic membrane of algae cells were isolated from the cells and extracted, and the gold content in the wall (membrane) was determined. By comparing with the gold content in the whole cells, The main enrichment sites for the cell wall (membrane) and some of the plasma membrane
