The aquaculture industry requires green solutions to solve several environmental challenges, including adequate wastewater remediation and natural drug applications to treat bacteria- and virus-related diseases. This study investigated the feasibility of cultivating the dinoflagellate in aquaculture wastewater from shrimp rearing in a synbiotic system (AWW-SS), with different dilutions of f/2 medium (FM). Interestingly, demonstrated enhanced growth in all AWW-SS treatments compared to the control (FM). The highest growth rates were achieved at AWW-SS:FM dilutions of 75:25 and 50:50. The removal of total nitrogen and total phosphorus reached 50.1 and 71.7%, respectively, of the crude AWW-SS. Biomass extracts of grown with AWW-SS were able to inhibit the growth of the bacteria (inhibition zone of 10.0 ± 1.7 mm) and (inhibition zone of 11.7 ± 1.5 mm). The presented results demonstrate that the dinoflagellate is a potential candidate for the development of circularity for sustainable aquaculture production, particularly by producing anti- compounds at a near-zero cost.
水产养殖业需要绿色解决方案来应对若干环境挑战，包括充分的废水修复以及应用天然药物治疗与细菌和病毒相关的疾病。本研究调查了在共生系统（养殖废水 - 共生系统，AWW - SS）中，用不同稀释度的f/2培养基（FM）培养甲藻用于虾养殖产生的水产养殖废水的可行性。有趣的是，与对照（FM）相比，所有AWW - SS处理组中的甲藻均显示出生长增强。在AWW - SS:FM稀释度为75:25和50:50时实现了最高生长速率。总氮和总磷的去除分别达到了粗AWW - SS的50.1%和71.7%。在AWW - SS中生长的甲藻生物量提取物能够抑制细菌（抑制圈为10.0±1.7毫米）和（抑制圈为11.7±1.5毫米）的生长。呈现的结果表明，甲藻是可持续水产养殖生产循环发展的潜在候选者，特别是通过以接近零成本生产抗菌化合物。
