Efficiency of ethanol and hexane extraction of sunflower oil from seeds of plants inoculated with Azospirillum brasilense and fertilized with sewage sludge

“…It is completely non-polar, readily dissolves oils, has low latent heat of vaporization, and does not react with pipes or equipment. However, hexane has high flammability, explosiveness, and toxicity (OETTERER et al, 2006;SILVA et al, 2020).…”

“…However, despite the high extractive power of hexane, it is used as a solvent requires great care and raises great concerns, ranging from storage and handling, to proper disposal (SILVA et al, 2005;SILVA et al, 2020). In addition, hexane can be emitted during the extraction process, which needs to recover the solvent, being able to react with other pollutants forming oxozium and photochemical oxidants (BAÜMLER et al, 2016).…”

“…In addition, it becomes an attractive solvent due to low cost and availability, as it is produced in Brazil on a large scale (CORREIA et al, 2010;SILVA et al, 2020).…”

“…It is safer, easier to handle, and less flammable than hexane, can be produced through biotechnological routes, and does not generate toxic waste. Furthermore, ethanol is widely available, reusable, and economically viable (SILVA et al, 2020). This study aimed to assess the efficiency of hexane and ethanol in extracting sunflower oil and determine whether inoculation with A. brasilense and fertilization with sewage sludge affects the yield of sunflower oil for biodiesel production.…”
