Enzymatic peeling of apricots nectarines and peaches
TOKER, İlkem; Bayındırlı, Alev (2003-03-01)
Different combinations of Peelzym (I, II, III and IV) concentration (0.1, 0.55, 1 cm(3) enzyme/100 cm(3) solution), temperature (20degreesC, 35degreesC, 50degreesC), pH (3.0, 4.5, 6.0) and time (20, 40, 60 min) were used for enzymatic peeling of apricots, nectarines and peaches. The optimum conditions were determined by using response surface methodology. Peeling yield, absorption of enzyme solution and texture changes were measured after peeling. For peeling of apricots with Peelzym IV, the optimum tempera...
Enzymatic production of xylooligosaccharides from cotton stalks
Akpinar, Ozlem; Ak, Ozlem; Kavas, Aysegul; Bakir, Ufuk; Yılmaz, Levent (2007-07-11)
Xylooligosaccharide (XO) production was performed from xylan, which was obtained by alkali extraction from cotton stalk, a major agricultural waste in Turkey. Enzymatic hydrolysis was selected to prevent byproduct formation such as xylose and furfural. Xylan was hydrolyzed using a commercial xylanase preparation, and the effects of pH, temperature, hydrolysis period, and substrate and enzyme concentrations on the XO yield and degree of polymerization (DP) were investigated. Cotton stalk contains about 21% x...

Enzymatic hydrolysis of fruit peels and other lignocellulosic biomass as a source of sugar for fermentation
Poçan, Pelin; Öztop, Halil Mecit; Hamamcı, Haluk; Department of Food Engineering (2015)
In this study, enzymatic hydrolysis of corn cobs, orange and pomegranate peels were evaluated. For the hydrolysis of corn cobs, effect of alkaline pretreatment was examined and it was found that glucose and reducing sugar yield (%) for the pretreated corn cobs increased from 7% to 21.5% and 14% to 33.6% respectively. Effect of cellobiase loading on hydrolysis efficiency was also investigated. It was observed that when cellobiase was added to hydrolysate in addition to cellulase, glucose and total reducing s...
Enzymatic Mineralization of Hydrogels for Bone Tissue Engineering by Incorporation of Alkaline Phosphatase
Douglas, Timothy E. L.; Messersmith, Philip B.; Chasan, Safak; Mikos, Antonios G.; de Mulder, Eric L. W.; Dickson, Glenn; Schaubroeck, David; Balcaen, Lieve; Vanhaecke, Frank; Dubruel, Peter; Jansen, John A.; Leeuwenburgh, Sander C. G. (Wiley, 2012-08-01)
Alkaline phosphatase (ALP), an enzyme involved in mineralization of bone, is incorporated into three hydrogel biomaterials to induce their mineralization with calcium phosphate (CaP). These are collagen type I, a mussel-protein-inspired adhesive consisting of PEG substituted with catechol groups, cPEG, and the PEG/fumaric acid copolymer OPF. After incubation in Ca-GP solution, FTIR, EDS, SEM, XRD, SAED, ICP-OES, and von Kossa staining confirm CaP formation. The amount of mineral formed decreases in the orde...
