Abstract An imminent change in the world energy matrix makes it necessary to increase production of renewable fuels. The United States and Brazil are world's largest producers, but their methods very different, using different raw materials, ground corn sugarcane juice, respectively. In recent years, strong investments have been made expand use Brazilian ethanol production. combination sugar ca...

Several types of lignocellulosic raw materials including wheat straw, sisal bagasse and sugarcane bagasse have different contents of cellulosic components. In our studies, aimed at isolating cellulose-degrading actinobacteria from Brazilian soils, a promising strain was selected and identified as Streptomyces sp. SLBA-08. This strain was tested for cellulase production under submerged fermentat...

Sugarcane (Saccharum Offcinarum L) is one of the important commodities for making sugar which has become a necessity industry and households. processed into granules or often known as brown located in Ketol District, Central Aceh Regency. Regency, especially West Blang Mancung Village, cane producers. an annual plant that its own characteristics, because stem there sugar, sugarcane plants belon...

Deteriorated sugarcane can lead to processing difficulties in the factory and to high levels of unwanted compounds in the raw sugar, with some extending to refined sugar. A high level of dextran is one of the more serious processing problems in a sugar factory that is associated with deteriorated cane. The development of a rapid test to measure an indicator of the ‘amount of deterioration’ coul...

Control of the raw material has considerable influence on final wine quality. The objective of this work was to develop a sensor capable of assessing grape juice quality in the cellar. Sensor response was compared with conventional chemical analysis using multivariate data techniques. The aroma sensor array is composed of 14 metal oxide sensors (MOS) gas transducers plus a temperature and a rel...

BACKGROUND Our dependence on fossil fuel sources and concern about the environment has generated a worldwide interest in establishing new sources of fuel and energy. Thus, the use of ethanol as a fuel is advantageous because it is an inexhaustible energy source and has minimal environmental impact. Currently, Brazil is the world's second largest producer of ethanol, which is produced from sugar...

background and objectives: recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...

This study was designed to investigate the effect of anaerobic digestion on biochar produced from sugarcane bagasse. Sugarcane bagasse was anaerobically digested to produce methane. The digested residue and fresh bagasse was pyrolyzed separately into biochar at 600 degrees C in nitrogen environment. The digested bagasse biochar (DBC) and undigested bagasse biochar (BC) were characterized to det...

The aim of the present study was to investigate the short-term (8-day) effects of feeding a raw soybean diet on exocrine pancreatic secretion and the plasma levels of gastrointestinal hormones in pigs. After adaptation to a heated soybean diet, 6 pigs (36.5 +/- 0.8 kg) were fitted with permanent fistulae of the pancreatic duct, the duodenum and a carotid artery. After post-surgical recovery of ...

The nutritional status, juice quality and sugar production of sugarcane varieties RB867515 RB92579 were evaluated in the cane-plant cycle, as a function magnesium doses applied at bottom planting furrow. study, installed soil with Mg content equal to 0.61 cmolc dm-3, was conducted an experimental design randomized blocks four replications. study 2 x 5 factorial: two varieties: RB92579, five mag...
