Agro-industrial residues have great potential as low-cost feedstocks for production of hydrolytic enzymes, which play a key role in the economics of cellulosic ethanol production. The goal of this research was to add value to agro-industrial byproducts such as wheat bran (WB), soybean bran, and ...

Sugarcane is among the leading agricultural crop cultivated in tropical regions of the world. Industrial processing of sugarcane generates sugar; as well as various solid wastes (i.e. sugarcane bagasse, pressmud). Improvement of biotechnology in industrial level, offers opportunities for economic...

Over the last few years the brazilian sugarcane sector has produced an average of 23.5 million liters of ethanol annually. This scale of production generates large amounts of vinasse, which depending on the manner that is disposed, can result significant greenhouse gas emissions. This study aimed...

The domestic wastewater effluents contain macro and micronutrients that are able to meet part or all of the nutritional needs of crops. Its use in agriculture is an ecological alternative that can minimize the impacts generated by the reduction of the wastes in the rivers, besides providing lower...

Brazilian ethanol is derived from sugarcane and is mostly used domestically as a transportation fuel either pure or mixed with gasoline. Brazilians will fill their cars with pure ethanol when its pump price in energy equivalent is lower than the price of gasohol, the mandatory mixture of ethanol...

Optimum utilization of fermentable sugars from lignocellulosic biomass to deliver multiple products under biorefinery concept has been reported in this work. Alcohol fermentation has been carried out with multiple cell recycling of Kluyveromyces marxianus IIPE453. The yeast utilized xylose-rich...

Sugarcane breeding programs have been adapting to a new market demand: aside from high sucrose yield per hectare, the sector needs new cultivars with higher fiber percentages. The selection of sugarcane clones based on phenotype alone is a complex task. The selected clones should display high...

This study considered the application of anaerobic digestion (AD) with phase separation combined with the use of an anaerobic structured-bed reactor (ASTBR) as the methanogenic phase for the treatment of sugarcane vinasse, a high-strength wastewater resulting from ethanol production. Two combined...

This section features the abstracts of papers presented during the symposium which focused on sugar biotechnological processes and diversification of sugar use. Topics explored in these papers include: (1) sugar use in the production of substitute petrochemicals; (2) sustainable biofuels from...

The very high gravity (VHG) process can improve the production through high ethanol titer up to 15% (v/v), nearly doubling the productivity [9.8 kg/(m³.h)], reducing vinasse to 5.4 L/L and minimizing the energy demand. The concept of this new process of high productivity and efficiency is based on...
