摘　　要：在有机磷农药——久效磷的胁迫下,叉鞭金藻细胞内产生了过氧化物酶(EC.1.11.7 POD)抑制因子.研究表明,此类过氧化物酶抑制因子是一类对高温不敏感、具较强的热稳定性的物质.它可能是通过减弱由POD催化合成的反应初始产物的稳定性来体现其抑制效应.The paper revealed that the peroxidase (EC. 1. 11. 7 POD) inhibitors were produced in Dicrateria sp. under organophosphorus pesticide-monocrotiphos stress. The POD inhibitors were some substances that were considerably stable to heat. It was evidently impossible for POD inhibitors to be phenolic compounds, protein and nucleic acides. The inhibition effect of POD inhibitors seemly acted on the initial products catalyzed by POD.
