Fuels and Chemicals from Hemicellulose Sugars
Industrial processes of lignocellulosic material have made use of only the hexose component of the cellulose fraction. Pentoses and some minor hexoses present in the hemicellulose fraction, which may represent...

Synthesis of Rigid Cyclodextrin-Containing Polymeric Resins for Adsorption
Cyclodextrins (CDs) are a family of cyclic-oligosaccharides with usually 6–8 glucopyranose units. Because of their unique donut-shaped steric structure they are able to form inclusion complexes selectively wit...

Effects of pressure pulsation on oxygen transfer rate measured by sulfite method
Pressure pulsation (PP) was investigated for its effects on oxygen transfer rate (OTR) measured by sulfite oxidation. By manipulating airflow rate, 0.41–1.2 vvm, and a control valve in a 4-L bioreactor, the fr...

Solid-state fermentation with Aspergillus niger for cellobiase production
Aspergillus niger NRRL3 was cultivated in a moist wheat bran and ground corncob solid medium supplemented with inorganic minerals for the production of cellobiase (β-1,4-glucosidase, EC 3.2.1.21). With this metho...
