Evaluación de la producción de etanol con dos cepas comerciales y dos tipos de mieles de caña provenientes de la región de Gualivá, departamento de Cundinamarca

Ethanol is a potential source of energy and its production from renewable biomass has acquired great popularity. Around the world research for its production is carried out through the use of regional substrates of low commercial value, organic waste and industrial waste. With this initiative a fermentation process was carried out, using two types of cane molasses, standard cane molasses and inverted cane molasses, as substrates, which were characterized according to pH, °Brix, density, viscosity and relative purity. These molasses went through a pasteurization process prior to inoculation and fermentation. Two commercial strains of Saccharomyces cerevisiae, ATCC® 4098 TM and ATCC® 9763 TM, isolated from white wine and from a distillery, were inoculated each for five days in a room controlling it’s temperature during this period Time, manual pressure releases were performed five times a day to avoid inhibition of strains; The fermentation was carried out at a concentration of 15 °Brix, a pH of 4.5 and 10% v/v of the inoculum for three days without aeration; Finally, ethanol production was determined using the mass spectrometry coupled with gas chromatography technique.
