Microalgae crops can generate a biochemical profile of high energy density and may be used for remediation of contaminated waste waters. This manuscript presents a laboratory-scale investigation into the potential for growing endemic microalgae biofilms in phosphorus-enriched nickel refinery tailings water, with an emphasis on product potential and the remediation of heavy metals. The dominant species of the consortia was a Chlorella-like microalga. The growth was monitored over time, with a productivity (0.77±0.07gAFDW.m.day) showing promising potential. The biochemical profile of biomass had a high total carbohydrate yield (40.0%), and a potential for increased lipid yields (6.7-19.5%). Biofilms showed a significant potential for the removal of heavy metals (Ni, Co, Mn, Sr) from the waste water with 24.8%, 10.5%, 24.8% and 26.4% reduction in Ni, Co, Mn and Sr, respectively. Results highlight significant potential for large-scale biofilm biomass production using metal-laden nickel refinery waste waters.
微藻作物可以产生高能量密度的生物化学特征，可用于受污染废水的修复。本文介绍了在富含磷的镍精炼厂尾矿水中生长地方性微藻生物膜的实验室规模研究，重点是产品潜力和重金属修复。 联合体的优势物种是一种类似小球藻的微藻。随着时间的推移监测了生长情况，生产力（0.77±0.07gAFDW.m.day）显示出了有希望的潜力。生物量的生物化学特征具有很高的总碳水化合物产量（40.0％），并且有增加脂质产量的潜力（6.7-19.5％）。生物膜显示出从废水中去除重金属（Ni，Co，Mn，Sr）的巨大潜力，Ni，Co，Mn 和 Sr 的去除率分别为 24.8％，10.5％，24.8％和 26.4％。结果突出显示了利用富含金属的镍精炼厂废水大规模生产生物膜生物量的巨大潜力。
