1. A Study of Chemical Composition and Enzymatic Hydrolysis of Solid Organic Waste from Agrosilvopastoral Systems
Agrosilvopastoral waste, regarding agriculture and agro-industry sectors, is pointed as a promising sustainable raw material for biofuels production, specially concerning exploitation of lignocellulosic organic residues for fermentable sugars and cellulosic ethanol output, being therefore necessary to investigate the potential of these substrates concerning

2. A SIMPLE EQUATION FOR TOTAL REDUCING SUGARS (TRS) ESTIMATION ON SWEET POTATO AND ETHANOL YIELD POTENTIAL
ABSTRACT Sweet potato is an attractive feedstock for ethanol production due to its high starch content and favorable agronomic characteristics. This paper proposes a simple equation to estimate the total reducing sugars (including glucose from starch) in sweet potatoes based on their moisture content (low cost and simple measurement). It allows the calculati

3. DETERMINAÇÃO DA INCERTEZA EXPANDIDA ASSOCIADA À ANÁLISE DE AÇÚCARES REDUTORES PELO MÉTODO DE LANEEYNON / DETERMINING THE UNCERTAINTY ASSOCIATED WITH THE EXPANDED ANALYSIS BY THE METHOD OF REDUCING SUGARS LANEEYNON
From the scientific viewpoint, the word uncertainty expresses doubt about an analytic result. The implementation of the concept of uncertainty of measurement is a crucial step that the Brazilian laboratories must take in the process for obtaining the certification of the ability to perform essays in accordance with the Brazilian technical norm ABNT NBR ISO/I

4. Sistemas de análises químicas em fluxo explorando multi-impulsão, interface única ou quimiometria / Flow systems exploiting multi-pumping, single interface or chemometry
Multi-pumping flow systems (MPFS) present as an unique feature the use of solenoid pumps as fluid propelling devices, which deliver pulsed flows. This flow regime was evaluated in order to improve mixing conditions between the involved solutions, heating transfer and gas diffusion.The association of the chemometric methods of analysis and MPFS systems was de

5. Evaluation of performance with alkaline hydrogen peroxide pretreatment for enzymatic hydrolisys of sugarcane bagasse / Avaliação de desempenho do pre-tratamento com peroxido de hidrogenio alcalino para a hidrolise enzimatica de bagaço de cana-de-açucar
The performance of alkaline hydrogen peroxide pretreatment to enable the enzymatic hydrolysis of sugar cane bagasse was evaluated. The objective is that the fermentable sugars obtained be used to ethanol production. 23 factorial designs were performed to evaluate the influence of pretreatment time (h), temperature (°C) and alkaline hydrogen peroxide concent

6. Development of thermal process otmized for mosto sugar canes in alcoholic fermentation / Desenvolvimento de processo termico otimizado para mosto de caldo de cana na fermentação alcoolica
In this research is proposed a thermal treatment process for sugar cane must with maximum retention of fermentable sugar (sucrose, glucose and fructose), to promote a thermal inactivation of its bacterial contaminants and therefore, those of alcoholic fermentation. With this objective were examined the thermo degradation kinetics of sucrose, glucose, fructos

7. Continuous ethanol production using yeast immobilized on sugar-cane stalks
Sugar-cane stalks, 2.0 cm long, were used as a support for yeast immobilization envisaging ethanol production. The assays were conducted in 38.5 L fermenters containing a bed of stalks with 50% porosity. The operational stability of the immobilized yeast, the efficiency and stability of the process, as well as the best dilution rate were evaluated. Molasses

8. O uso de fermento reciclado com teor reduzido em metabolitos e seu efeito na fermentação alcoolica
This trial was conducted to evaluate the influence of metabolites presents in wine, from separated materials by Melle-Boinot process in the parameters of alcoholic fermentation simulated in laboratory conditions. The experiments were taken using Saccharomyces cerevisiae (IZ 1904) and juice of molasse from Piracicaba County, State of São Paulo, Brazil, with
