13. Sugarcane straw as a feedstock for xylitol production by Candida guilliermondii FTI 20037
Abstract Sugarcane straw has become an available lignocellulosic biomass since the progressive introduction of the non-burning harvest in Brazil. Besides keeping this biomass in the field, it can be used as a feedstock in thermochemical or biochemical conversion processes. This makes feasible its incorporation in a biorefinery, whose economic profitability c

18. Rheological and thermal characteristics of wheat gluten biopolymers plasticized with glycerol
The objective this work was to obtain bioplastics from mixtures of wheat gluten and glycerol by two different processes and evaluate their respective rheological properties. The mixtures and their respective bioplastics were obtained through direct batch mixing under approximately adiabatic and isothermal conditions. The bioplastics showed high values for th

20. Estudo dos fenômenos de transporte em cromatografia através da aplicação de modelos de rede e estocásticos / Study of transport phenomena in chromatography by application of network and stochastic models
The study of different phenomena of separation has been most important for the different areas of industry and science. Due to the large computational available, we can model and analyze the chromatographic phenomena at the microscopic level. The network model has been most used to represent processes of separation by chromatography, because through them we

21. DESENVOLVIMENTO DE UM PROCESSO CONTÍNUO PARA PRODUÇÃO DE BIODIESEL A BAIXAS TEMPERATURAS. / DEVELOPMENT OF A CONTINUOUS PROCESS FOR PRODUCING BIODIESEL AT LOW TEMPERATURES.
Biodiesel has emerged worldwide as a promising alternative to oil-derived mineral fuels. It is biodegradable, renewable, obey to the carbon cycle and can be defined as fatty acid monoalquyl esters derived from renewable sources, such as vegetable oils and animal fats. It can be produced from a transesterification reaction, in which there is the transformatio

22. Production of bio-inseticide Bacillus thuringiensis var. israelensis in semicontinuous processes combined with batch processes for sporulation
The aim of this work was to study the production of the bioinsecticide using the aerobic cultivation. Two-stage cultivation process was used: aerobic vegetative growth and end-phase of sporulation (with aeration and without aeration). The cuts of working volume evaluated were 20, 40, 60 and 80 %. The highest value of spore concentration (2.17x10(9) CFU/mL) a
