Este trabalho é fruto de pesquisas sobre as relações entre Igreja e Estado no Brasil do século XIX. O objetivo é apresentar um panorama dos debates políticos em torno da Questão Religiosa - principal evento no Segundo Reinado (1842-1889) envolvendo, o clero e a política imperial -, cujas discussões percorreram o Senado, a Câmara dos Deputados, o Conselho de Estado, o poder judiciário, e a sociedade como um todo, sobretudo nos jornais, entre 1872 e 1875. O conflito aconteceu a partir da tentativa de dois Bispos de separar o culto católico das práticas maçônicas. A Questão Religiosa revela-se no Brasil como um verdadeiro embate, entre a defesa e o prolongamento dos princípios liberais da Constituição Imperial de 1824, e, o movimento mundial da Igreja católica de reação ao liberalismo, emplacado no Syllabus um documento lançado em 1864 pelo Papa Pio IX listando os 80 erros da sociedade moderna. Nessa perspectiva a dissertação divide-se em duas partes. A primeira trata do conceito de secularização e o quadro político frente à religião católica na Europa. E a segunda lida com a Questão Religiosa no Brasil e com quatro posicionamentos diferentes, sobre as relações entre os poderes político e religioso, que foram expressos na década de 1870.

Production of bioethanol through acidic and enzymatic hydrolysis of aquatic Azolla sp., as a new source of bio-mass, has been performed, as a means to control increasing growth and reducing undesirable effects of this plant in Anzali lagoon. After sampling, drying and crushing, Azolla was hydrolyzed, using diluted acid and enzyme. Diluted acid hydrolysis was done using both autoclave and a high-pressure system (Batch Synth® Microwave synthesizer). The effects of temperature and time (in autoclave) and concentration of acid (in both) were compared. Cellubrix®, a ommercial cellulase source, was used for enzymatic hydrolysis process. The amounts of reducing sugars, glucose and furfural, released from hydrolyzate, were measured. To produce alcohol, Sacchromyces cerevisiae (to ferment sixcarbon sugars), Zygowilliopsis californica and Pichia stipitis (to ferment five-carbon and sixcarbon sugars) were used. Maximum amounts of glucose (4.83% w/w) and reducing sugars (14.15% w/w) were obtained using acid hydrolysis in autoclave. In the microwave oven, maximum glucose (5.04% w/w) and reducing sugars (13.27 w/w) were obtained at 180 and 200 °C, respectively. Under these conditions, maximum produced furfural was 1.54 g/L. The difference between amounts of furfural obtained from acid hydrolysis of Azolla in microwave oven compared to autoclave was statistically significant. Amounts of alcohol produced and its yields were 3.99 g/L and 33.13% for S. cerevisiae in 48 hours, 3.73 g/L and 30.45% for Pichia stipites in 48 hours, and 3.73 g/L and 30.45% for Z. californica in 24 hours after inoculation, respectively, with significant differences. Statistical comparison of results showed significant differences (P<0.05) in glucose production, at different conditions. Amounts of reducing sugars and glucose increased after optimization of levels of acid, time, and temperature. The overall optimum released sugar and glucose were obtained with 1.67% (w/v) acid using autoclave. Higher temperatures in microwave oven caused a significant increase (P<0.05) in furfural. Furfural severely inhibits fermentation. Hence, regarding the issues of energy consumption and time, amounts of inhibiting substances and sugar production, autoclave is found to be superior to the high temperature and pressure, generated in microwave oven, for hydrolyzing Azolla. Furthermore, given the amounts of Azolla in Anzali lagoon, it may be recommendable to use this plant as a biomass resource.
