Abstract
The bacterial exopolysaccharides (EPS) enticed the researchers because of its natural protection against predators, and adhesion to the surface. Thus, this study was conducted for the EPS production from Exiguobacteriumsp. VK2, the synthesis of Carbon Quantum Dot (CQD) from EPS and it was further used for bioenergy production. The CQD was synthesized and characterized using hydrothermal reaction and its structure was elucidated by several methods like Fourier transform infrared (FT-IR) spectrum, UV–visible spectroscopy, Gas chromatography-Mass spectroscopy (GC-MS), X-ray diffraction (XRD), HR-TEM, SAED (Selected Area Electron Diffraction) spectrum, Atomic Force Microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and Brunaur-Emmett-Teller (BET) analysis. Further, the synthesized CQD from EPS of Exiguobacterium sp.VK2 was tested for its catalytic activity in biodiesel production from waste cooking oil (WCO) along with two different conventional catalysts and more than 90% of total fatty acid methyl ester (FAME) was achieved by CQD than the control.
