Effluents obtained through a supercritical water gasification (SCWG) process at 400 and 600 °C were mixed with Bristol Medium to cultivate . Improvement of growth rate was observed only for the medium with the effluent at 600 °C. Low non-purgeable organic carbon implied that the inhibiting material was decomposed due to the high temperature of 600 °C. Thus, SCWG effluents might be more suitable for algae cultivation than hydrothermal liquefaction effluents. Phosphorus accumulation in was improved in the SCWG mixed medium, irrespective of the treatment temperature. The media with SCWG effluents showed 2.5 times higher phosphorus accumulation in the algae, indicating the possibility of using a combination of and SCWG for nutrient recycling processes.
在400℃和600℃下通过超临界水气化（SCWG）过程获得的流出物与布里斯托尔培养基混合用于培养。仅在含有600℃流出物的培养基中观察到生长速率的提高。低不可吹扫有机碳表明抑制物质由于600℃的高温而分解。因此，SCWG流出物可能比热液液化流出物更适合藻类培养。无论处理温度如何，SCWG混合培养基中藻类的磷积累都有所改善。含有SCWG流出物的培养基中藻类的磷积累高出2.5倍，这表明将藻类和SCWG结合用于营养物循环过程的可能性。
