Cotton stalk, a lignocellulosic waste material, is composed of xylose that can be used as a raw material for production of xylitol, a high-value product. There is a growing interest in the use of lignocellulosic wastes for conversion into various chemicals because of their low cost and the fact that they are renewable and abundant. The objective of the study was to determine the effects of H(2)SO(4) concentration, temperature, and reaction time on the production of sugars (xylose, glucose, and arabinose) and on the reaction by-products (furfural and acetic acid). Response surface methodology was used to optimize the hydrolysis process in order to obtain high xylose yield and selectivity. The optimum reaction temperature, reaction time, and acid concentration were 140 A degrees C, 15 min, and 6%, respectively. Under these conditions, xylose yield and selectivity were found to be 47.88% and 2.26 g g(-1), respectively.

The effects of microbial lignocellulose pretreatments on xylooligosaccharide production Uckun, E.; Ak, O.; Bakir, U. (Elsevier BV, 2009-09-01) Lignocellulosic agricultural waste materials are produced in huge amounts in the world and regarded as abundant, inexpensive readily available natural sources for various industries. They are mainly composed of three types of macromolecules, cellulose, hemicellulose and lignin. Cellulose and hemicellulose are converted to a variety of valuable compounds such as enzymes, hormones, antibiotics, ethanol, sugar alcohols, organic acids and xylooligosaccharides (XOs) using bioprocessing methods easily after the r...
Early weight bearing of porous HA/TCP (60/40) ceramics in vivo: A longitudinal study in a segmental bone defect model of rabbit Balcik, Cenk; Tokdemir, Turgut; Senkoylu, Alpaslan; Koc, Nursen; Timucin, Muharrem; Akın, Serhat; Korkusuz, Petek; Korkusuz, Feza (Elsevier BV, 2007-11-01) Porous interconnected hydroxyapatite (HA) and HA/tricalcium phosphate (TCP) (60/40) ceramics are promising materials for hard tissue repair. However, the mechanical properties of these materials have not been accurately determined under weight-bearing conditions. In this study, newly developed HA and HA/TCP (60/40) ceramics were used with intramedullary fixation in segmental bone defects of rabbits. Early radiological, histological, densitometric and biomechanical changes were evaluated. The mean radiologic...
Effect of Oxygen Tension and Medium Components on Monomer Distribution of Alginate Moral, Cigdem Kivilcimdan; Doğan, Özdemir; Sanin, Faika Dilek (Springer Science and Business Media LLC, 2015-06-01) Alginate is a natural biopolymer composed of mannuronic and guluronic acid monomers. It is produced by algae and some species of Azotobacter and Pseudomonas. This study aims to investigate the effect of dissolved oxygen tension (DOT) and growth medium substrate and calcium concentrations on the monomeric composition of alginate produced by Azotobacter vinelandii ATCCA (R) 9046 in a fermenter. Results showed that alginate production increased with increasing DOT from 1 to 5 %. The highest alginate production...
Development of a paper-type tyrosinase biosensor for detection of phenolic compounds Senyurt, Ozge; EYİDOĞAN, FÜSUN; Yilmaz, Remziye; Oz, M. Tufan; Ozalp, V. Cengiz; Arica, Yakup; Öktem, Hüseyin Avni (Wiley, 2015-01-01) A low-cost, portable, and disposable paper-type tyrosinase biosensor was developed for determination of phenolic compounds, using a paper-strip absorption method. Tyrosinase and a chromophore (3-methyl-2-benzothiazolinone hydrazone) were immobilized on paper strips to manufacture the biosensor, which was tested on a nontoxic substrate (l-dopamine). The biosensor was responsive to phenolic compounds such as 4-chlorophenol, catechol, m-cresol, and p-cresol. The sensor showed stability for 70days. The develope...
KINETIC ASPECTS OF THE FERMENTATION OF COTTON FIBERS AT DIFFERENT PH VALUES IN A FERMENTER INOCULATED WITH RUMEN MICROORGANISMS TUKENMEZ, I; OZILGEN, M; BICER, A (Elsevier BV, 1991-11-01) Rumen microorganisms were used in a batch fermentor to investigate whether they could be used to produce acetic acid, propionic acid, butyric acid, and methane from cotton fibers. The kinetics of product formation were studied with the initial medium pH values of 6.0, 7.0, and 8.0. Propionic acid, butyric acid, and methane production were growth associated; acetic acid production was found to be nongrowth associated. The largest amounts of bacteria and protozoa were attained with the initial pH of 7.0. T...
