| This study aimed to evaluate the efficiency of natural biocides, brown and green propolis, for the control of bacterial contamination in the production of sugarcane spirit. The treatments consisted of brown and green propolis extracts, ampicillin, and a control and were assessed at the beginning and end of harvest season in ten fermentation cycles. In the microbiological analyses, the lactic acid bacteria were quantified in the inoculum before and after the treatment with biocides, and the viability of yeast cells during fermentation was evaluated. The levels of acids, glycerol, total residual reducing sugars, and ethanol were analyzed for the wine resulting from each fermentation cycle. A reduction in the number of bacterial contaminants in the inoculum... |

| The objective of this study was to evaluate the effect of Moringa oleifera Lam. leaf extract on the sedimentation of impurities in the treatment of sugarcane juice and the effects on sugar quality and on the clarified juice. The experimental design used was a 4x2 factorial arrangement with four replications. The main treatments performed included the extracted original sugarcane juice, the synthetic polyelectrolyte (Flomex 9076), the leaf extract, and a control. The secondary treatments consisted of the sugarcane varieties RB92579 and RB867515. The clarification process used was simple defecation, in which the flocculating agents and the juice, limed and heated, were poured simultaneously into a decanter. The microbiological and chemico-technological... |

| Os biocombustíveis apresentam-se com grande importância para suprir a demanda global de energia. São produzidos a partir de biomassa vegetal, emitem menor quantidade de dióxido de carbono e de partículas poluentes ao ambiente quando utilizados e possuem grande vantagem por serem combustíveis renováveis. Entre as matérias-primas com potencial para produção de etanol, cita-se o sorgo sacarino. Objetivou-se comparar o processamento industrial do genótipo de sorgo sacarino CVSW80007 e da cultivar de cana-de-açúcar 'RB966928' para produção de bioetanol em início de safra. As análises realizadas foram: brix; pH, ART, AR, acidez total, ARRT, glicerol, teor alcoolico, viabilidade celular, viabilidade de brotos e brotamentos. Quanto às características... |
