The aim of this study is to cultivate Spirulina platensis and Scenedesmus obliquus microalgae in consortia using effluents of cattle waste anaerobic treatment in order to give possibilities to the production of microalgae biomass to biorefineries uses. The biomasses obtained were characterized to evaluate the potential for the production of biofuels and other bioproducts. The effluent was used in sterile and non-sterile conditions to better understand the influence of other microorganisms in N and P removal. The biomass obtained with the addition of 10% of sterile effluent in Zarrouk media (20%) presented 44.12 and 34.62% of carbohydrates, using Spirulina platensis in monoculture or the 50%/50% consortia of Spirulina and Scenedesmus, respectively, this biomass presenting the potential to be used to bioethanol production. Nitrogen and phosphorous removal were higher in non-sterile conditions and reached 92.7 and 49.66% of nitrogen and phosphorous removal, respectively, using the consortia and with the addition of 30% effluent in the media. The cultivation of microalgae in a consortium may be used to assist the treatment of water concurrently with the production of biomass to different applications.

这项研究的目的是利用牛粪厌氧处理的废水在联盟中养殖螺旋藻和斜生藻微藻，以便为生物精炼厂使用微藻生物质的生产提供可能性。表征获得的生物质以评估生产生物燃料和其他生物产品的潜力。废水用于无菌和非无菌条件，以更好地了解其他微生物对氮和磷的去除效果。在Zarrouk介质加入无菌流出物的10％（20％）获得该生物质呈现44.12和碳水化合物的34.62％，使用钝顶螺旋藻单养或的50％/ 50％财团螺旋藻和景物分别是这种生物质，具有用于生物乙醇生产的潜力。在非无菌条件下，使用联合体并在培养基中添加30％的废水后，氮和磷的去除率更高，分别达到92.7和49.66％的氮和磷去除率。联合体中微藻的培养可用于协助水处理，同时生产生物质以适应不同的应用。
