摘要:
研究不同质量浓度硝基苯(nitrobeneze)对汉氏菱形藻(Nitzschia hantzschia)生长、可溶性糖含量、可溶性蛋白含量、叶绿素a含量和藻细胞导电率的影响。结果表明,随着硝基苯质量浓度的升高,汉氏菱形藻的生长受到抑制,处理5 d时藻培养液依次由深黄色逐渐变为浅黄色;2 d后可溶性糖含量升高,1 d时100 mg/L硝基苯处理组可溶性蛋白含量为对照组的89.1%,为最低值,之后呈现逐渐上升趋势。低质量浓度硝基苯对藻细胞叶绿素a含量有促进作用,中、高质量浓度有抑制作用,而50 mg/L处理3 d后叶绿素a含量逐渐恢复;藻细胞的电导率随硝基苯质量浓度的升高而逐渐升高,低质量浓度处理3 d后电导率逐渐恢复,而高质量浓度伤害藻细胞,导致汉氏菱形藻逐渐死亡。
