摘　　要：为揭示不同碳氮比对纤毛虫种群增长的影响以及纤毛虫对碳源和能量来源的选择性 ,利用实验生态学方法 ,对海水养殖水体中 3种常见的纤毛虫原生动物 :扇形游仆虫 (Euplotesvannus)、海洋尾丝虫 (Uronemamarinum)和巨大拟阿脑虫 (Paranophrysmagna)在牛肉浸膏及梯度浓度葡萄糖培养基中的种群增长过程进行了初步的探讨 .数据分析表明 ,在牛肉浸膏培养基中加入不同浓度的葡萄糖对于纤毛虫种群增长影响显著 ,其中在 0 .0 5 gL-1葡萄糖浓度的培养基中 3种纤毛虫种群增长最佳 (P <0 .0 5 ) ,而在 0 .4 gL-1浓度时纤毛虫的生长繁殖均受到高度抑制 (P <0 .0 5 ) .这一结果显示 ,不同C N比对纤毛虫的种群增长有着直接的影响 .图 3表 3参The population growth of three marine ciliated protozoa,Euplotes vannus,Uronema marinum and Paranophrys magna,was investigated using experimental ecological method in beef extract medium with a range of glucose concentrations in order to reveal the effect of different CN ratio on population growth of ciliates and the selectivity of ciliates to the resources of carbon and energy. The results exhibited that the medium with 0.05 g L -1 glucose concentration was the most available one for culturing marine ciliates,the population growth was inhabited when the concentration of glucose reached the level of 0.4 g L -1 . When cultivated in the medium with 0.05 g L -1 glucose concentration,the population density of all the three marine ciliates could be increased to a high level. The results give some helpful information to evaluate the effects of CN ratio in medium on the population growth of marine ciliates. Fig 3,Tab 3,Ref 10
