摘　　要：比较了蒽对自养条件下的蛋白核小球藻、普通小球藻和原始小球藻及异养条件下原始小球藻的毒性效应. 结果表明,它们对蒽的耐受性大小趋势为:原始小球藻(异养)> 蛋白核小球藻(自养)> 普通小球藻(自养)>原始小球藻(自养),其EC50值(96 h)分别为2.53,1.47,1.27,0.85 m g/L.Toxic effects of anthracene on \$Chlorella pyrenoidosa. Chlorella vulgaris\$ and \$Chlorella protothecoides\$ heterotrophic condition were compared in our study. It was demonstrated that the consequence of their resistant ability was \$C.protothcoides\$ (Heterotrophic)>\$C.pyrenoidosa\$ (Autotrophic)> \$C.vulgaris\$ (Autotrophic) > \$C. protothcoides\$ (Autotrophic). And the EC 50 values were 2.53 mg/L(24 h), 1.47 mg/L(96 h), 1.27 mg/L(96 h), 0.85 mg/L(96 h), respectively.
