Última Ethanol fermentation of a diluted molasses medium by Saccharomyces cerevisiae immobilized on chrysotile BABT Monte Alegre,Ranulfo; Rigo,Maurício; Joekes,Inés. In this work, the catalytic role of chrysotile support on the acceleration of alcoholic fermentation under non-aseptic conditions by Saccharomyces cerevisiae was investigated. The fermentation medium employed consisted only of diluted sugar-cane molasses. In the batch fermentations process with immobilized yeasts, the initial rate of CO2 production increased roughly 27 % during the first 30 minutes, compared to systems containing no chrysotile. A study of continuous alcoholic fermentation with chrysotile in the reactor bed showed a higher ethanol production rate at the different dilution rates investigated compared to similar fermentations without chrysotile.

Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132003000400031 Catechol biodegradation kinetics using Candida parapsilopsis BABT Rigo,Maurício; Alegre,Ranulfo Monte; Bezerra,José Raniere Mazile Vidal; Coelho,Narjara; Bastos,Reinaldo Gaspar. This study evaluated the biodegradation of catechol by a yeast strain of Candida parapsilopsis in standard medium in Erlenmeyer flasks. Results shown that the highest concentration of catechol caused the longer lag period, demonstrating that acclimatized cultures could completely degrade an initial catechol concentration of 910 mg/L within 48 h. Haldane's model validated the experimental data adequately for growth kinetics over the studied catechol concentration ranges of 36 to 910 mg/L. The constants obtained for this model were µmax = 0.246 h-1, Ks = 16.95 mg/L and Ki = 604.85 mg/L.
