Sugarcane processing for ethanol and sugar in Brazil

Development of NaY zeolite derived from biomass and environmental assessment of carbon dioxide reduction

“…Bagasse is by-product of sugar industry obtained after the extraction process. This by-product was used in different processes such as fuel resources [8] which sugarcane bagasse is burnt in the boiler, producing steam that is expanded in turbines coupled with electric generators [9] and silica source [10]. Bagasse ash is a general term describing all forms of the ash produced from burning bagasse.…”

Evaluation of microorganisms performance in hemicellulosic hydrolyzate detoxification and sugarcane bagasse lignin removal for ethanol production

“…According to Dias et al (2015Dias et al ( , 2011, sugarcane is transported from the field to the plant and prepared for juice extraction by milling. After extraction, impurities (minerals, salts, organic acids, dirt and fine fiber particles) are removed from sugarcane juice in the juice treatment system by a physicochemical treatment.…”

“…It has been used as feedstock for production of ethanol on a large scale basis in Brazil for over three decades. Apart from ethanol, most of the sugarcane mills produce sugar and electricity (DIAS et al, 2015). Sugarcane trash, such as bagasse and leaves fuels the cane processing plants, providing electricity to the grids through cogeneration.…”

“…Currently, first generation of bioethanol is produced from the easily extracted sugars from sugar-containing or starchy biomass, such as sugarcane (CARDONA; QUINTERO; PAZ, 2010;COELHO et al, 2006;DIAS et al, 2015;MARTINELLI;FILOSO, 2008) and corn (BIAŁAS; SZYMANOWSKA; BOTHAST;SCHLICHER, 2005;SHIGECHI et al, 2004). First generation biofuels present several challenges, such as food and fuel competition, change in land-use and potential increased greenhouse gas emissions, due to fossil fuel are utilized in the upstream processes.…”

Clonagem, expressão e purificação de glicosil hidrolases (GH5 e GH45) provenientes do fungo <i>Gloeophyllum trabeum</i> e estudo da ação das proteínas como auxiliares na hidrólise de polissacarídeos

“…Nos dois casos, a fonte de açúcar fermentecível é de fácil obtenção: sacarose do caldo de cana e glicose a partir da hidrólise enzimática do amido contido no milho. Por outro lado, existe uma expectativa atual de que a próxima geração de biocombustíveis (denominados de segunda geração) seja produzida a partir de rejeitos agrícolas e/ou florestais (biomassa lignocelulósica), maximizando o uso da área plantada e ampliando o número de países envolvidos na produção de biocombustíveis (DIAS et al, 2015). No entanto, o processamento da biomassa lignocelulósica para a produção de etanol de segunda geração é mais complexo e requer a conversão eficiente de seus polissacarídeos a monômeros fermentescíveis (HARRIS et al, 2014 …”
