Extraction of sugar total reducers “ART” of “coronta” of Zea mays “yellow maize lasts”

Abstract

The alternative to use residual lignocelulósicos in the ethanol production and the singel cell protein production nowadays constitutes a highly promising possibility by its ample availability in the world. In this work, different hydrolysis methods of the residual lignocelulósico of “coronta” of Zea mays “yellow maize lasts” was to evaluate with the purpose of determining the method most appropriate for the extraction the sugar total reducers “ART” and power this to use it like substrate in fermentatives processes for the singel cell protein and bioetanol production. “coronta” dry and fractional of a particle size < 0,001 m and chemical, physical hydrolysis methods and the combination were evaluated of both using like extractantes solutions sterile summarizing distilled water, sulfuric acid and hidróxido of sodium to 1,25 %. The relationship coronta-solvent used in all the treatments was of 1:10. The determination sugars total reducers were carried out filtrates obtained of each one of the treatments using the method of Folin-Wu. The results indicate that the maximum concentration of sugar total reducers corresponding to 20,220 g/L is obtained after carrying out the mixed hydrolysis as resulting of the combination of the physical and chemical method.
