• Abstract

  The ethanol that accumulates in the broth during the alcoholic fermentation is the main toxic component for yeast, affecting its growth and limiting the industrial ethanol production. In this way, the process is limited to the use of musts with moderate concentrations of fermentable sugars, producing wines with low ethanol concentration (8 to 11ºGL), which requires a large amount of energ…

  Extractive Ethanol Fermentation in Pneumatic Bioreactors with Removal by CO2 Stripping Integrated to Recovery Units, AP.R

• Abstract

  In this project will be studied experimentally and by simulation, production and recovery ethanol process alternative to conventional ethanol fermentation process followed by the distillation stage. It is proposed to study the extraction and recovery of the ethanol in the fermented wine without cells, produced in conventional process or ethanol of the broth during extractive fermentation …

  Study of Integrated Process for Ethanol 1G Production and Recovery, AP.PITE

• Abstract

  This project proposes to evaluate and compare performance criteria of conventional bioreactor (stirred and aerated tank) operated with different impellers, and non-conventional bioreactors (bubble column and airlift) with different geometries, as well as compare the performances of such equipment in the production processes of clavulanic acid by Streptomyces clavuligerus and cellulases by…

• Abstract

  The microbubble generation has attracted rising scientific interest. It is known that microbubbles increase mass transfer efficiency in gas-liquid dispersions. So, the use of microbubbles is indicated for many applications at bench and industrial scales. However, the microbubbles application in extractive fermentation with ethanol removal by CO2 stripping is still unexplored. In this proc…

  Microbubbles generation in pneumatic bioreactors: application in extractive ethanol fermentation using carbon dioxide as stripping gas, BP.DR

• Abstract

  Currently there is a great economic and environmental concern regarding the energy sources used. In anticipation of the scarcity and / or limitation of the use of fossil fuels for environmental reasons, it is necessary to search for renewable and sustainable alternative energy sources. One of the alternatives that takes into account the use of agricultural residues as lignocellulosic mate…

  Influence of spores concentration and pH on the Aspergillus niger morphology and endoglucanases production, BP.IC

• Abstract

  The low ethanol content reached in wine is the main restriction of the alcoholic fermentation process in the distilleries. Ethanol is accumulated in the fermentation broth and reaches toxic levels, acting as a noncompetitive inhibitor of metabolism. One way to overcome this problem is to apply the gas stripping technique for the removal of ethanol during fermentation. In this project, int…
