The biotransformation of these pentoses into ethanol is one of the most important scientific and technological challenges requiring solution (Rossel, 2006; Silva, Mussatto, Roberto, & Teixeira, 2011; 2012).
Other ingredients of the aloe include galactose, uronic acids and pentoses.
Consumption of xylose may be explained by the degradation of this pentose during the fermentation process or due to its internalization by endocytosis in the Saccharomyces cerevisiae yeasts, which, although did not metabolize pentoses, are capable of absorbing them internally (SUBTIL & BOLES, 2012).
Lactobacillus plantarum, Lactobacillus pentoses, Lactobacillus casei 393 were used to make them competent.
Clostridium bacteria can utilize different types of sugars including hexoses several pentoses oligo- and polysaccharides for bio-butyric acid production while C.
O amido e a celulose sao polissacarideos que consistem em unidades de hexose, a hemicelulose e um heteropolissacarideo formado por uma mistura de monomeros de pentoses e hexoses, a lignina e um polimero tridimensional complexo formado por compostos fenolicos e os oleos consistem de triglicerideos.
Esse aumento e responsavel pela ativacao do ciclo das pentoses e consequente inducao da saida da dormencia das gemas (OMRAN, 1980).
Sugars, including dextrose, sucrose and pentoses like xylose are reasonable platform chemicals since they are substrates for most fermentation processes and their sugar alcohols are substrates for hydrgenolysis to glycols as discussed above.
Since additional ethanol could be produced from pentoses, or five-carbon sugars, as conversion technology improves, the NIRS method can be used to estimate what the total potential yield of ethanol or other biofuels would be if all sugars in the plant were converted.
