水体环境因子对波吉卵囊藻亚硝酸盐氮吸收速率的影响
Effects of water environmental factors on the uptake rate of nitrite nitrogen by Oocystis borgei
摘要
Abstract
The effects of temperature, light intensity, salinity, pH and algal concentration on uptake rate of nitrite nitrogen by Oocystis borgei were studied through adding stable isotope tracer in the simulated condition. The result showed that temperature, light intensity, pH and algal concentration had a significant influence on the uptake rate of nitrite nitrogen by Oocystis borgei (P < 0. 05 ). The uptake rates reached maximum when temperature was 25 °C , light intensity was 4 500 lx, salinity was 30, pH was 7.5, or algal concentration was 4. 5 x 105 cell/mL; their values were 0. 106 |xg N/( g ? H) , 0. 118 jxg N/( g ? H) , 0. 125 jxg N/(g ? H) , 0. 129 |xg N/(g ? H) , and 0. 129 juug N/(g ? H) , respectively. An oneway analysis of variance revealed that the factor combination for optimal uptake rate was 25 t for temperature, 4 500 lx for light intensity, 30 for salinity, 7. 5 for pH, and 4. 5 x 105 cell/mL for algal concentration. Therefore, we can improve the uptake rate of nitrite nitrogen by Oocystis borgei through controlling the environment factors to promote water quality of shrimp culture.关键词
