Shrimp farm effluents are one of the principal causes of eutrophication in coastal environments. Integrated processes of bioremediation involving the culturing of purifying organisms have been suggested, but very few studies have focused on microalgae. For that purpose evaluated the growth potential of Amphora sp. in the residual waters of shrimp farm activity fulfilled on the Paraíba State, Brazil. The experiments were performed using Conway medium as the control and wastewaters from shrimp farm at 100% concentrations. Amphora sp. demonstrated good growth in the shrimp farm effluents under test conditions, although less than that observed in the control medium. This diatom was found to removed 73.357 and 72.572% of PO and NO, respectively, demonstrating a high mitigation potential for this type of effluent. Comparisons of the physiological responses measured by flow cytometry demonstrated higher cell densities of Amphora sp. in the control medium, but a higher lipid content was observed in Amphora cultured in shrimp farm effluents.
虾场废水是沿海环境富营养化的主要原因之一。人们已经提出了涉及培养净化生物的生物修复综合过程，但很少有研究关注微藻。为此，评估了在巴西 Paraíba 州虾场活动的剩余废水中 Amphora sp. 的生长潜力。实验使用 Conway 培养基作为对照，并用 100%浓度的虾场废水进行。在测试条件下，Amphora sp. 在虾场废水中表现出良好的生长，但低于对照培养基中的生长。该硅藻对 PO 和 NO 的去除率分别为 73.357%和 72.572%，表明对这种废水具有很高的缓解潜力。通过流式细胞术测量的生理响应比较表明，Amphora sp. 在对照培养基中的细胞密度较高，但在虾场废水中培养的 Amphora 中观察到更高的脂质含量。
