HIGHLIGHTS Brachiaria brizantha proved to be a promising biomass for ethanol production. Fermentation was not impaired by the inhibitors furfural and hydroxymethylfurfural....
This study aimed to evaluate the effects of increasing levels of chitosan (CHI) on sugarcane fermentation profile and losses, chemical composition, and in situ degradation. Treatments were: 0, 1, 2, 4, and 8 g of CHI/kg of dry matter (DM). Twenty experimental silos (PVC tubing with diameter 28 cm and hei...
Background: Fuels and chemicals from renewable feedstocks have a growing demand, and acetone, butanol and ethanol (ABE) are some relevant examples. These molecules can be produced by the bacterial fermentation process using hydrolysates generated from lignocellulosic biomass as sugarcane bagasse, one of ...

Resumo Este artigo explora um dos aspectos mais interessantes e menos estudados no Brasil: as consequências das experiências complexas e contraditórias da substituição total de bebidas tradicionais indígenas pela cachaça, introduzida pelo contato interétnico. Contribui com a carência de ampliaç...
SUMMARY: Peripheral nerve regeneration is a serious clinical problem. The goal of this work was to evaluate comparatively a biopolymer tube of sugarcane with an expanded polyethylene tube as a tube guide in peripheral nerve regeneration. Fourteen male albino Wistar rats were used, separated into three di...
ABSTRACT Vinasse is a byproduct of the process of distillation of sugarcane juice for the manufacture of sugar and alcohol. Because it is rich in nutrients, mainly potassium (K), is used as fertilizer and applied via fertigation, without concerning for the fate of this compound in the soil. Thus, the obj...
ABSTRACT One of the most important steps is to clarify the juice, which are added synthetic polymer acrylamide base, aiming the fast settling of impurities present in the juice. However, this input is expensive and may have carcinogenic and neurotoxic actions to humans. The search for new natural floccul...

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 incorpo...

Avaliou-se o efeito do ambiente ruminal sobre a degradação da FDN de 12 cultivares de cana. As dietas continham: 87,1% de cana (Cana) ou 42,0% de cana e 58,0% de concentrado com milho (Milho) ou polpa cítrica (Polpa). Seis vacas com cânula ruminal formaram quadrados latinos 3x3. Por 11 dias de cada p...
This experiment was designed to evaluate the effects of the inclusion of detoxified castor bean meal (CM) content on the chemical-bromatological composition, as well as the fermentation characteristics and dry matter losses of sugarcane silage. The treatments consisted of four levels (0, 7, 14 and 21% na...
