In the process of alcohol fermentation, the kinetic data were obtained for the sugar and yeast Here is These fermentations were carried out only with mango pulp. The results of these treatments showed that higher cell densities are given with 200 g/L of initial sugar, however reducing sugar in the sample concentration is not recommended for alcohol fermentation of mango pulp at high concentrations, given the fact the sugar is not completely metabolized andtherefore there is a loss of 40 percent of the reducing sugar
