15. Cachaça Production in Brazil and its Main Contaminant (Ethyl Carbamate)
ABSTRACT This review aims to demonstrate the possible formation of Ethyl carbamate (EC) in different production stages of cachaça. EC is a carcinogen confirmed in animal experiments and possibly carcinogenic to humans. EC incidence below relevant health limits naturally affects many fermented foods and beverages. Concentrations above 1 mg L–1 are often de

16. Endophytic Actinomycetes as Potential Producers of Hemicellulases and Related Enzymes for Plant Biomass Degradation
Abstract Tailor made enzymatic preparation must be design to hydrolyze efficiently plant biomass, once that each plant biomass possesses a distinct cell wall composition. Most of actinomycetes used for plant cell wall degradation are focused on the cellulases and xylanases production. However, a wide range of enzymes must be produced for an efficient degrada

17. INFLUENCE OF PRETREATMENTS ON CRYSTALLINITY AND ENZYMATIC HYDROLYSIS IN SUGAR CANE RESIDUES
ABSTRACT This research evaluated the effect of different delignification pretreatments (enzymatic and organosolv), on the crystallinity and enzymatic hydrolysis of harvested sugar cane residues. The Crystallinity Index (CrI), the Relative Number of Intensity (Ir), the degree of cellulose mercerization (IIC-%), and the Global Index of Saccharification (GIS) w

18. CAROTENOID-PRODUCING YEASTS IN THE BRAZILIAN BIODIVERSITY: ISOLATION, IDENTIFICATION AND CULTIVATION IN AGROINDUSTRIAL WASTE
ABSTRACT Different yeast strains from forests located in southern Brazil, with potential to produce carotenoids, were isolated. Three microorganisms were selected as potential carotenoid producers. Sporiodiobolus pararoseus, Rhodotorula mucilaginosa and Pichia fermentans were grown in Yeast Malt (YM) medium and the carotenoids produced identified as cryptoxa

19. ISOLATION AND IDENTIFICATION OF YEAST STRAINS FROM SUGARCANE MOLASSES, DATES AND FIGS FOR ETHANOL PRODUCTION UNDER CONDITIONS SIMULATING ALGAL HYDROLYSATE
ABSTRACT Yeast strains were isolated from sugar cane molasses (S1), dates (S2) and figs (S3) and the ethanol production was evaluated in batch condition. A comparison was made with the yeast Saccharomyces cerevisiae. The strains showed tolerant characteristics to stressful conditions like salinity and ethanol. The isolated strains produced ethanol; at 20 h o

20. Lactobacillus plantarum LPBR01 as inoculant in sugarcane silage
ABSTRACT. Sugar cane is highly productive (dry matter.hectare-1), but after ensiling process nutritional quality is affected, thus additives are needed to control or minimize losses. This study aimed to evaluate if Lactobacillus plantarum LPBR01 strain used as silage inoculant for sugar cane can control fermentation losses. Sugar cane samples (72) were divid

21. Population Changes of Eubacteria, Sulfate-Reducing Bacteria and Methanogenic Archaea in an Anaerobic Reactor Processing Ethanol Distillery Vinasse
Abstract The microbiological characterization by molecular techniques (DGGE and quantitative PCR) of Archaea, Bacteria domain and sulfate-reducing bacteria (SRB) from a laboratory scale Up-flow Anaerobic Sludge Blanket (UASB) processing sugar cane vinasse was performed during the operational phase with increasing organic loads. The organic load removal effic

22. Reciclagem de éter-aminas, utilizadas na flotação de minério de ferro, por meio da adsorção
RESUMO O presente trabalho teve por objetivo verificar uma possível rota de reciclagem para as éter-aminas, utilizadas para aumentar a eficiência do processo de flotação catiônica reversa do minério de ferro. Estudou-se um método de separação físico-química utilizando TANFLOC como floculante. As águas de rejeito contêm, em sua maior parte, amin

23. TORREFIED BRIQUETTES OF SUGAR CANE BAGASSE AND EUCALYPTUS
RESUMO A torrefação e a briquetagem são duas técnicas que melhoram a qualidade da biomassa e facilitam seu uso direto como combustível. O objetivo do trabalho foi avaliar o efeito da temperatura de torrefação nas propriedades dos briquetes compostos produzidos com bagaço de cana-de-açúcar e serragem de eucalipto. Após o preparo das amostras e aná

24. Biosurfactant Production by Bacillus strains isolated from sugar cane mill wastewaters
Abstract Biosurfactants possess diverse chemical properties and provide important characteristics to the producing microorganisms, which can act as surface-actives and emulsifiers of hydrocarbon and others water insoluble substances. Most of them are lipopeptides synthetized by Bacillus. This study evaluated the biosurfactant production by strains of Bacillu
