Ethanol production by co-culture of Zymomonas mobilis and Pachysolen tannophilu...
Ferreira, Juliana; Santos, Vidiany Aparecida Queiroz; Cruz, Crispin Humberto GarciaEthanol production by Zymomonas mobilis CCT 4494 and Pachysolen tannophilus CCT 1891 co-cultures and individual fermentation from each microorganism are evaluated with hydrolysate of banana peels. Banana peels hydrolysate was obtained by sulfuric acid pretreatment followed by enzymatic saccharification, carried out on solid fraction and used as substrate by individual and co-cultures of Z. mobilis and P. tannop...
Ethanol and Levan production by sequential bath using Zymomonas mobilis immobil...
Santos, Vidiany Aparecida Queiroz; Cruz, Crispin Humberto GarciaCurrent study evaluates ethanol and levan production using Zymomonas mobilis immobilized on alginate and chitosan beads and assesses the capacity of the beads for reuse in sequential fermentations. Two experiments were carried out: In the first experiment 2(5-2) design evaluated the following independent variables: sucrose concentration; pH; incubation time; temperature and agitation. In the second experiment, ...
Analysis of kinetic parameters for levan production by Zymomonas mobilis using ...
Ernandes, Fernanda Maria Pagane Guereschi; Cruz, Crispin Humberto GarciaLevan is an exopolysaccharide synthesized by several microorganisms during fermentation of a culture medium containing sucrose, yeast extract and minerals. This biopolymer has applications in the food segment as stabilizers, thickeners, as carriers for flavor and fragrances, as well as in the pharmaceutical segment as a hypocholesterolemic agent and for exhibiting antitumor activity. This work aimed to analyze ...
Influence of medium composition in the production of ethanol by Zymomonas mobil...
Ernandes, Fernanda Maria Pagane Guereschi; Boscolo, Maurício; Cruz, Crispin Humberto GarciaThe production of ethanol using Zymomonas mobilis had been reported to be three to four times larger than with Saccharomyces cereviseae. The influence of pH, temperature and composition of the means of fermentation are parameters that can direct the metabolism for the production of ethanol. The objective of this study was to evaluate the production of ethanol by Zymomonas mobilis CCT 4494, by variations of the ...
