The present work aims to evaluate the potential for bioremediation and CO₂ fixation by cultivating the microalgae of the genus Chlorella minutissima in cassava wastewater. Experimental work investigated the growth of microalgae in the effluent and determined its growth rate based on different dilutions. Four culture media scenarios were created. The values measured in the laboratory were compared with a mathematical model adjusted based on the kinetic growth. The efficiency of the process was evaluated in terms of the reduction of the organic load, nutrient consumption, and cell count in the initial state (time 0) and complete growth (after the seventh day) using microscopy analysis. After biological treatment, a percentage of reduction of COD (chemical oxygen demand) of around 30%, TS (total solids) 75%, nutrient removal 92%, cyanide near 99%, and average CO₂ biofixation 0.19 g L⁻¹ d⁻¹ were observed. The reduction percentages are close to those found in the literature for other cultivation media. It was observed in this study that the biomass productivity and CO₂ fixation agree with those obtained in other studies and confirm the efficiency of the very tiny Chlorella microalgae with high photosynthetic capacity.

目前的工作旨在通过培养微小小球藻属的微藻来评估生物修复和 CO ₂固定的潜力。在木薯废水中。实验工作调查了废水中微藻的生长情况，并根据不同的稀释度确定了其生长速率。创建了四个文化媒体场景。将实验室测量的值与基于动力学增长调整的数学模型进行比较。使用显微镜分析，在初始状态（时间 0）和完全生长（第 7 天后）下，根据有机负荷的减少、养分消耗和细胞计数来评估该过程的效率。生物处理后，COD（化学需氧量）降低百分比约 30%，TS（总固体）75%，营养物去除率 92%，氰化物接近 99%，平均 CO ₂生物固定 0.19 g L ^-1 d ^{- 1}被观察到。减少百分比接近于其他栽培介质的文献中发现的百分比。在本研究中观察到，生物质生产力和 CO ₂固定与其他研究中获得的一致，并证实了具有高光合能力的非常微小的小球藻微藻的效率。
