Microalgal cultivation in wastewater can significantly reduce the nutrient requirements and helps in wastewater management. In this study, was cultured on cigarette butt leachate admixed with culture medium. The cigarette butt leachate concentrations in the culture medium were set from 0 % to 100 % and a maximum biomass production was achieved at 60 % concentration (1.24 g L). The lipid content of was increased by 9.98 %, carbohydrate content by 40.93 % and protein content by 42.93 % with 60 % of cigarette butt leachate concentration as compared to the control. Water quality analysis after microalgal cultivation revealed that the N and P elements in the cigarette butt leachate wastewater were removed completely by the microalgal growth. Life cycle assessment (LCA) analysis was carried out to evaluate the environmental sustainability of the process, which has revealed that the cigarette butt leachate wastewater has significant reduction in the environmental impacts with a CO emission reduction up to 338 %. The study empirically suggested that the cigarette butt leachate mixed culture medium has potentially promoted the growth, lipid and protein in which can improve the upstream economics along with the environmental benefits of waste management.

在烟蒂渗滤废水改良的培养基中培养原壳小球藻，以提高生物量和大分子产量

在废水中培养微藻可以显着降低营养需求并有助于废水管理。在这项研究中，在与培养基混合的烟蒂渗滤液上进行培养。培养基中的烟蒂浸出液浓度设置为 0% 至 100%，最大生物量产量在 60% 浓度下实现（1.24 g L）。烟蒂浸出液浓度为60%时，与对照相比，脂质含量增加9.98%，碳水化合物含量增加40.93%，蛋白质含量增加42.93%。微藻培养后的水质分析表明，烟蒂渗滤液废水中的N和P元素被微藻生长完全去除。通过生命周期评估（LCA）分析来评估该工艺的环境可持续性，结果表明烟蒂渗滤液废水对环境的影响显着减少，二氧化碳排放量减少高达338%。该研究凭经验表明，烟蒂渗滤液混合培养基具有潜在促进生长、脂质和蛋白质的作用，可以提高上游经济效益以及废物管理的环境效益。
