The present study aims to investigate the biofuel production ability and potential of heavy metal remediation of Chlorella sp. ISTLA1 isolated from a landfill site. The strain was cultured in Bold’s Basal medium at different concentration of NaHCO3 and pH. Response surface methodology was employed for the optimization of nutrient sources for higher lipid production. Under the optimized conditions, the yield of lipid and biomass was 365.42 and 833.14 mg L−1 respectively. GC–MS analysis of lipid indicated the presence of C8 to C31 organic compounds consisting mainly of palmitic acid (C16:0), stearic acid (C18:0) and oleic acid (C18:1). Additionally, remediation of heavy metals like Zn, Cu, Mn and Fe from waste water was observed by AAS and EDX. The removal efficiency was 82.6% for Zn, 56.5% for Cu, 79.8% for Mn and 40% for Fe. The study revealed simultaneous biodiesel production and waste water treatment by Chlorella sp. ISTLA1.

生物燃料的生产和phycoremediation通过小球藻ISTLA1与垃圾填埋场隔离

本研究旨在调查小球藻的生物燃料生产能力和重金属修复潜力。ISTLA1与垃圾填埋场隔离。该菌株在Bold氏基础培养基中以不同浓度的NaHCO 3和pH进行培养。响应面方法被用于优化营养来源,以提高脂质的产量。在优化条件下,脂质和生物质的产量分别为365.42和833.14 mg L -1。脂质的GC-MS分析表明存在C 8至C 31主要由棕榈酸(C16:0),硬脂酸(C18:0)和油酸(C18:1)组成的有机化合物。此外,通过AAS和EDX观察到了废水中重金属如Zn,Cu,Mn和Fe的修复。锌的去除效率为82.6%,铜的去除率为56.5%,锰的去除率为79.8%,铁的去除率为40%。该研究表明小球藻同时生产生物柴油和废水。ISTLA1。
