2. Behavior of industrial strains of Saccharomyces front inhibitory compunds present in sugarcane molasses in the production of biothenol / Comportamento de linhagens industriais de Saccharomyces frente a compostos inibitorios presentes no melaço de cana-de-açucar na produção de bioetanol
The general objective of this project was the evaluation of the effects of some organic substances present in molasses, sugar cane on strains of yeast for industrial use. Chapter I refer to a brief introduction and history of alcoholic fermentation. In Chapter II, samples of industrial molasses were examined, from 10 units producing sugar, located in the sta

3. Otimização dinâmica da fermentação alcoólica no processo embatelada alimentada
This work presents an experimental and theoretical study of the dynamic optimization of the alcoholic fermentation in fed-batch mode utilizing the Saccharomyces cerevisiae yeast in a bioreactor of 5 L. Twelve experiments were carried out, three them in batch and nine in fed-batch mode, with initial sucrose concentrations between 154 and 195.6 g/L for the exp

5. Biotechnological production of surfactante of Bacillus subtilis in agro-industrial residue, characterization and applications. / Produção biotecnologica de surfatante de Bacillus subtilis em residuo agroindustrial, caracterização e aplicações.
Biosurfactants are amphypatic compounds from biologycal source showing both hydrophilic and lipophilic groups. Due to this feature, the biosurfactants acts decreasing the surface and interfacial tension of a liquid. The byproducts of agricola and industrial processing are an underexplored new sources to the production of biotechnological interesting compound

6. Influencia da materia-prima no comportamento cinetico de levedura na produção de etanol
The purpose of this work was to analyze the kinetic behavior of the yeast strain (Y904Mauri do Brasil) using nine molasses with different exhaustion levels coming from sugar and alcohol producing units. The relationship was evaluated between the product production specific rate and the microbial growth specific rate. The essays were made in a bench bioreac

7. Classificação das cepas de leveduras dominantes de processos fermentativos utilizando parametros fermentativos e taxonomia numerica
In fermentatives processes for alcohol production is common the development of yeasts that are not the one which were selected as inoculum. These yeasts, when present, can show good fermentatives qualities or not. Thus, the microbiological control in the alcoholic fermentation is important for the detection of the wild yeasts, together with the evaluation of
