Abstract

A sustainable media composition comprising of nanourea (NU), groundnut de-oiled cake (GDOC), and seaweed Extract (SE) was formulated using a mixture design for the cultivation of Micractinium sp. Maximum biomass yield and productivity of 5.52 ± 0.09 g L⁻¹ and 0.72 ± 0.03 g L⁻¹ d⁻¹ were observed at 1.67 mM NU, 0.134 g L⁻¹ GDOC and 0.250 mL L⁻¹ SE, respectively. The highest lipid yield of 2.73 ± 0.24 g L⁻¹ was also observed, respectively. The reduced graphene-supported vanadium oxide nanoparticles (RGO-VNPs) with a net surface charge of + 34.10 mV were developed, which acted as a flocculant as well as a catalyst for transesterification. A maximum flocculation efficiency of 98 % was observed with 200 ppm of RGO-VNPs. The Fatty Acid Methyl Ester (FAME) yield of 96.81 ± 1.61 % was observed. Thus, the present study could provide a plausible solution for one-pot harvesting and synthesis of biodiesel utilizing microalgal lipids.

最大限度地利用小ractinium sp.生物质，并使用两用还原石墨烯支撑氧化钒纳米粒子进行收获和后续生物柴油生产

采用混合设计法配制了由纳米尿素（NU）、落花生脱油饼（GDOC）和海藻提取物（SE）组成的可持续培养基组合，用于培养小苍兰。在 1.67 mM NU、0.134 g L-1 GDOC 和 0.250 mL L-1 SE 条件下，观察到最高生物量产量和生产率分别为 5.52 ± 0.09 g L-1 和 0.72 ± 0.03 g L-1 d-1。脂质产量最高，分别为 2.73 ± 0.24 g L-1。还原石墨烯支撑的氧化钒纳米颗粒（RGO-VNPs）的净表面电荷为 + 34.10 mV，既是絮凝剂，也是酯交换反应的催化剂。在使用 200 ppm 的 RGO-VNPs 时，絮凝效率最高可达 98%。脂肪酸甲酯（FAME）的产率为 96.81 ± 1.61%。因此，本研究为利用微藻脂类进行生物柴油的单锅收获和合成提供了一种可行的解决方案。
