Ethanol production has gained great prominence in the investment new renewable energy sources and Brazil is among the leaders of production. However, this activity generates large amounts of waste being the largest volume of the sugar cane bagasse. For this reason looking up ways to use this material as burning for energy production and composition of forage in the diet of ruminants, however there are difficulties to use this production for this last one. This paper proposes a microbiological treatment with Lentinula edodes and Pleurotus ostreatus in order to enable the bagasse in ruminant feed composition in order to be used more noble than their burning. After treatment with the fungus, tests were performed for quantifying crude protein by the method of Kjeldhal. It was verified that the protein content in the pure bagasse was 1.0% after fermentation the protein content was 4.2% with L.edodes and 4.9% with P. ostreatus. To evaluate the protein quality of the product fermented by L. edodes and P. ostreatus was applied microbiological method for growth of Enterococcus zimogenes verifying that after fermentation the protein quality was 76 and 27.4% with L. edodes and P.ostreatus, respectively, compared with casein. The quantification of amino acids showed significant improvement of protein with altered amino acid profile with treatments of fungos. About of DQO and BOD were also found considerable improvement besides considerable drop in toxicity as measured by acute toxicity test with Daphinia similis

The present work focuses on addressing the financing made by BNDES to sucroalcooleiras plants located in the State of São Paulo in Brazil. The study points out the Bank loans at São Paulo due to accumulation of plants technical objects that BNDES loans provide the State, with the installation of new equipment, machinery and services in canavieiros enterprises for electric power generation. Sucroalcooleiras plants are getting financing from BNDES to expand and diversify power generation in the country, mainly in São Paulo, because residential and industrial consumption of electricity grows annually. The offer of new financing to sucroalcooleiras plants for energy production Sao Paulo electric provides continued technical density in São Paulo and the expansion of regional inequality in the country. Therefore, the present study highlights for the period 2008 to 2013 the BNDES financing for are sucroalcooleiras plants in order to highlight the consolidation of technical objects in the State and show that the funding will help in the expansion of regional disparity
