Estudio comparativo de la eficiencia volumétrica y alcohólica del bioetanol de primera generación (1G) obtenido del jugo de naranja Thompson (Citrus sinensis) a diferentes concentraciones de levadura (Saccharomyces cerevisiae).

Abstract

The purpose of this research is to determine the volumetric and alcoholic efficiency of bioethanol obtained from Thompson orange juice. The study was carried out under an experimental methodology where three different treatments were carried out based on the inoculation of Saccharomyces cerevisiae in different concentrations (0.1%, 0.5% and 1%) and with a volume of orange juice of 250 mL. The treatments carried out based on the different combinations and repetitions, allowed to obtain 1G bioethanol. According to the quantities obtained, various analyzes were carried out to measure both the volumetric and alcoholic efficiency of bioethanol. The results obtained show that treatments of 1% of Saccharomyces cerevisiae registered the highest volumetric quantity with an average of 56.25 mL of bioethanol. Alcoholic efficiency from concentrations of 0.5% of Saccharomyces cerevisiae generated 20% alcohol, being the highest degree recorded. The total cost considering the expenses of reagents, mobilization, and raw material determine an index of USD 1,822 per 1mL of bioethanol produced.
