摘要/Abstract

摘要： 以两种海洋微藻金藻8701(Isochrysis galbana8701)和骨条藻(Skeletonema costatum)为材料,研究了低浓度蒽(1.5～6μg·L^-1)对两种海洋微藻生长的影响.结果表明,在一定浓度蒽作用下,两种微藻的生长均呈现出较明显的“兴奋效应”,细胞密度有所增加,但达到最佳刺激作用的浓度与时间有所不同.在刺激浓度作用下,两种微藻体内的蛋白质、叶绿素a(chla.)、类胡萝卜素(car.)含量都有所增加,其变化趋势与细胞密度的变化类似.在整个实验过程中,微藻体内清除活性氧的关键性酶超氧化物歧化酶(SOD)始终处于较高水平,其变化趋势类似于细胞密度的变化.

Abstract: Two species of marine microalgae, Isochrysis galbana 8701 and Skeletonema costatum,were exposed to low concentration of anthracene,and their cell density,contents of chlorophyll a,carotinoid and protein,and superoxide dismutase (SOD) activity were examined. It was showed that low concentration of anthracene (1.5～6.0μg·L) could obviously stimulate the growth of these microalgae, and their protein,chlorophyll a, and carotinoid contents increased with increasing cell density. SOD of treated groups remained high activity,compared with the controlled group during the whole experiment.
