Hydrolysis of the hemicellulosic fraction sugarcane bagasse by sulphuric acid was performed in laboratory (25 mL) and semi-pilot L) reactors under different conditions temperature, time concentration. On scale, three highest recovery yields were obtained at: 140ºC for 10 min with 100 mg acid/g dm (yield=73.4%); 20 (yield=73.9%) 150ºC 70 (yield=71.8%). These also used hydrolysis a reactor, xylose yield (83.3%) at
Abstract The use of dilute acids to catalyze the hydrolysis hemicellulose its sugar constituents is well‐known and effective. However, a major problem associated with this pretreatment poor fermentability produced hydrolyzate as result presence microorganismapos;s inhibitory compounds. In present work, seven ion‐exchange resins were tested in order detoxify corn stover hydrolyzate. Regarding xylose recovery, it was observed that more than 92% recovery feasible. Furfural removal varied from...
Many attempts have been made to establish the control of foodborne pathogens through Lactobacillus isolates and their metabolism products with success being obtained in several situations. The aim this study was investigate antagonistic effect eight Lactobacillusisolates, including L. caseisubsp. pseudoplantarum,L. plantarum, reuteri delbrueckii subsp. delbrueckii, on pathogenic Escherichia colistrain O157:H7. inhibitory pure cultures two pooled supernatants growth bacteria evaluated by spot...
Sugarcane bagasse hydrolysate (initial acetic acid concentration = 3.5g/L), was used as a fermentation medium for conversion of xylose into xylitol by the yeast Candida guilliermondii FTI 20037. Acetic (2.0g/L) added to at different times fermentation, with aim evaluating its effects on bioconversion process. The addition after 12h resulted in strongest inhibition metabolism. In this case, consumption and cell growth were, respectively, 23.22 11.24% lower than when beginning fermentation. As...
The effect of glucose on xylose-to-xylitol bioconversion by Candida guilliermondii was examined adding it to sugarcane bagasse hydrolysate medium obtain different glucose:xylose ratios (1:25, 1:12, 1:5 and 1:2.5). Under experimental conditions, increasing ratio improved the assimilation xylose present in yeast, resulting biomass increase, formation xylitol glycerol/ethanol by-products. Maximum values yield (0.59 g g-1) volumetric productivity (0.53 l-1.h-1) were obtained with 1:5, higher...
