小球藻大量养殖中经常出现轮虫等微型浮游动物污染,往往会对生物量生产造成破坏性影响。在这项研究中,五种表面活性剂被用来控制污染的轮虫,萼花臂尾轮虫,蛋白核小球藻XQ-20044培养。实验结果表明,表面活性剂对B.对于伯醇乙氧基化物、十二烷基苯磺酸钠、醇醚硫酸钠、椰子二乙醇酰胺和十二烷基硫酸钠,calyciflorus分别为7.5、10、10、10和15 mg L− 1。而仅10 mg L-1十二烷基苯磺酸钠和7.5-10 mg L-1伯醇乙氧基化物对藻类生长没有负面影响。此外,在一个5 m2的开放式跑道池塘中,10 mg L− 1的十二烷基苯磺酸钠确保了轮虫的快速和完全消除,而藻类的最终干重达到>0.74 g L− 1,而使用十二烷基苯磺酸钠的成本仅为0.014美元。本研究结果表明,十二烷基苯磺酸钠的方法是快速,高效,低成本的处理。因此,十二烷基苯磺酸钠在微藻大量培养过程中具有很大的生物污染控制潜力,且不会对藻类生长产生负面影响。
Frequent microzooplankton contamination such as rotifers in Chlorella mass culture often causes devastating effects on biomass production. In this study, five surfactants were used to control contamination by a rotifer,Brachionus calyciflorus, in Chlorella pyrenoidosa XQ-20044 cultures. Laboratory results showed that the minimal effective concentrations of surfactants for complete control ofB. calycifloruswere 7.5, 10, 10, 10, and 15 mg L−1for primary alcohol ethoxylate, sodium dodecylbenzene sulfonate, sodium alcohol ether sulfate, coconut diethanolamide, and sodium dodecyl sulfate, respectively. However, only 10 mg L−1sodium dodecylbenzene sulfonate and 7.5–10 mg L−1primary alcohol ethoxylate had no negative effects on algal growth. Moreover, in a 5 m2open raceway pond, 10 mg L−1sodium dodecylbenzene sulfonate ensured swift and total elimination of rotifers, while the final dry weight of the algae reached >0.74 g L−1whereas the cost of using sodium dodecylbenzene sulfonate was only $ 0.014. The results of this study indicated that sodium dodecylbenzene sulfonate approach is fast-acting, highly effective, and a low-cost treatment. Therefore, sodium dodecylbenzene sulfonate has great potential for biological contamination control in microalgae mass culture without a negative impact on algal growth.
