Influência das variáveis nitrogênio, fósforo e ºBrix na produção dos metabólicos secundários contaminantes totais da fermentação alcoólica

Abstract: Recebido em 13/4/05; aceito em 23/9/05; publicado na web em 12/4/06 INFLUENCE OF NITROGEN, PHOSPHORUS AND ºBRIX ON THE PRODUCTION OF TOTAL SECONDARY CONTAMINANT METABOLITES (MSCT) OF ALCOHOLIC FERMENTATION. The present study evaluated the influence of nitrogen, phosphorus and ºBrix on the production of MSCT through a factorial design methodology and analysis of response surface. The objective was to propose a statistically significant probabilistic model for the alcoholic fermentation. In order to obtain less … Show more

“…The yield of 87.15% is lower than that typically found in the discontinuous or semi-continuous fermentation of alcohol when using a solution consisting of sugar cane juice, molasses, or a mixture of the two (SILVA et al, 2006). Silva et al (2008) optimised the fermentation of grape cane using the response surface methodology as a statistical tool and obtained, through discontinuous fermentation, a yield of 88%, which is close to the value obtained in experiment 6 (Table 1) NH 4 H 2 PO 4 .…”

“…Maximum alcohol content was estimated on total sugar and Gay-Lussac equation for alcoholic fermentation, in which 1 mol of glucose (180 g) produced 2 moL of ethanol (92 g), 2 moL of carbon dioxide (CO 2 ) (88 g) and 238.26 kJ of energy (SILVA et al, 2006). Yield was determined according to the expression:…”

“…Yeast extract was used, with NH 4 H 2 PO 4 as the nitrogen and phosphorus source and MgSO 4 .7H2O (0.25 g L -1 ) and ZnSO 4 (0.2 g L -1 ) added to the medium as magnesium and zinc sources, respectively (CORDENUNSI et al, 1985;SILVA, 2006;ZIMMERMAN, 1970).…”
