Two phases were established: an aerobic phase evaluating temperatures of 20ºC and 37ºC with an inoculation rate of 4% and 1vvm (volume/volume of medium per minute) and an anaerobic phase at a temperature of 10ºC, which were monitored for a period of 36 hours. The main kinetic parameters such as specific growth rate, doubling time and the percentage of ethanol produced by the Winnick technique were determined. The results showed that the best temperature to produce biomass of S. cerevisiae is given around 20ºC with concentrations of 1.30x108 cells/ml with a maximum peak biomass production at 21 hours, which differ significantly from the other treatments evaluated (Sig.=0.000). The highest production of ethanol was obtained in the treatment of 20% glycerin and 10% of inoculum of the microorganism (p<0.05) at a temperature of 10ºC, corresponding to 176.87mg of ethanol/ml of glycerin. Therefore, the viability of this agroindustry by-product is deduced as an alternative source for the biomass and ethanol production from Saccharomyces cerevisiae.application/pdf10.1088/1742-6596/1126/1/0120081742-65961742-6588https://repositorio.udes.edu.co/handle/001/3132engJournal of Physics: Conference SeriesRights - Institute of Physics Publishing, 2018info:eu-repo/semantics/openAccessAtribución-NoComercial 4.0 Internacional (CC BY-NC 4.0)https://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf2https://iopscience.iop.org/article/10.1088/1742-6596/1126/1/012008/pdfEthanolSaccharomyces cerevisiaeDetermination of the percentage of ethanol produced by Saccharomyces cerevisiae from semi-purified glycerinArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85PublicationTHUMBNAILDetermination of the percentage of ethanol produced by Saccharomyces cerevisiae from semi-purified glycerin.pdf.jpgDetermination of the percentage of ethanol produced by Saccharomyces cerevisiae from semi-purified glycerin.pdf.jpgGenerated Thumbnailimage/jpeg1313https://repositorio.udes.edu.co/bitstreams/0e68e13e-16a3-40b8-a3e3-ca36fe0a8ae7/download624e92a4d781c75f8c52c07b720ec750MD54ORIGINALDetermination of the percentage of ethanol produced by Saccharomyces cerevisiae from semi-purified glycerin.pdfDetermination of the percentage of ethanol produced by Saccharomyces cerevisiae from semi-purified glycerin.pdfapplication/pdf273063https://repositorio.udes.edu.co/bitstreams/428c6a76-0612-4d10-88a1-fc6f0f0610fb/download4c7d0d607a2a2519ed79d2eeacd7609cMD55LICENSElicense.txtlicense.txttext/plain; charset=utf-859https://repositorio.udes.edu.co/bitstreams/81fd072a-54e2-48b5-985b-cdcd555da7c9/download38d94cf55aa1bf2dac1a736ac45c881cMD52TEXTDetermination of the percentage of ethanol produced by Saccharomyces cerevisiae from semi-purified glycerin.pdf.txtDetermination of the percentage of ethanol produced by Saccharomyces cerevisiae from semi-purified glycerin.pdf.txtExtracted texttext/plain24830https://repositorio.udes.edu.co/bitstreams/1a36a167-ea7e-422e-ac56-10d69d947f70/download6d794f36b4c51556ad2c5c37b4562bafMD53001/3132oai:repositorio.udes.edu.co:001/31322023-10-11 08:56:07.603https://creativecommons.org/licenses/by-nc/4.0/Rights - Institute of Physics Publishing, 2018https://repositorio.udes.edu.coRepositorio Universidad de Santandersoporte@metabiblioteca.comTGljZW5jaWEgZGUgUHVibGljYWNpw7NuIFVERVMKRGlyZWN0cmljZXMgZGUgVVNPIHkgQUNDRVNPCgo= |
