To evaluate the effects of dietary hemicellulose from corn on growth and metabolic measures, female pigs (n = 48; initial BW 30.8 kg) were fed diets containing 0 to 38.6% solvent-extracted corn germ meal for 28 d. Increasing the hemicellulose level had no impact on ADG or ADFI, but resulted in a quadratic response (P < 0.03) on G:F. To investigate physiological changes that occur with increased...

Coptotermes formosanus is one of the most destructive termites in the southern part of Japan as well as in the United States. Hemicellulose is a noncellulosic polysaccharide found in plant cell walls, and xylan is the major constituent of hemicellulose. Since hemicellulose prevents access of cellulolytic enzymes to cellulose, enzymatic hydrolysis of hemicellulose is beneficial for cellulose dig...

In this study we investigated resveratrol (trans-3,5,4'-trihydroxystilbene) solubilization with sodium 3α,12 α-dihydroxy-7-oxo-5 β-cholanoate (S7-OD) and sodium dodecyl sulfate (SDS). The investigation was aimed at determining whether large spherical micelles (SDS) or small longitudinal micelles (S7-OD) are more convenient for incorporation of resveratrol. Also, we studied resveratrol behavior ...

Acrylonitrile was graft polymerized onto ground, water-washed wheat straw using Fe2 +-H 20 2 as initiator. Reaction conditions were selected to minimize homopolymer formation and ma.xi.mize the amount of polyacrylonitrile (PAN) grafted to straw. Polymerizations typically yielded straw-g-PAN containing 30-35% PAN. A two-step fractionation scheme was developed for determining the relative amounts...

In order to exploit a fast-growing Paulownia hardwood as an energy crop, xylose-enriched hydrolysate was obtained in this work increase the ethanol concentration using hemicellulosic fraction, besides already widely studied cellulosic fraction. For that, elongata x fortunei submitted autohydrolysis treatment (210 °C or S0 of 4.08) for xylan solubilization, mainly xylooligosaccharides. Afterward...

BACKGROUND There are many different types of pretreatment carried out to prepare cellulosic substrates for fermentation. In this study, one- and two-stage hydrothermal pretreatment were carried out to determine their effects on subsequent fermentations. The two substrates were found to behave differently during fermentation. The two substrates were then characterized using physical and chemical...

Controlled pH, liquid hot water pretreatment of corn stover has been optimized for enzyme digestibility with respect to processing temperature and time. This processing technology does not require the addition of chemicals such as sulfuric acid, lime, or ammonia that add cost to the process because these chemicals must be neutralized or recovered in addition to the significant expense of the ch...
