| Abstract: | The aim of this study was to examine the effect of laccase pretreatment on the cellulose extraction of corn straw with deep eutectic solvent (DES). All pretreatments significantly differed in separation of hemicellulose and lignin, and further in extraction efficiency of cellulose. The overall performance of laccase/xylanase system (LXS) exhibited the highest level between various pretreatment processes, whereas the lowest had the absence of mediator to the pretreatment. The highest differences were observed in the extraction efficiency of cellulose. The viscosity-average molecular weight (Mv) of the obtained cellulose varied from 22678.5 of the control sample to 24871.6 of the LXS sample and the cellulose yield from 42.9% to 99.2%, in which the temperature required in DES-based extraction was only 90 C, far lower than that commonly used in DES-based extraction of straws. The mechanism of pretreatment effect was explained according to the composition and texturality together with lignin substructures. |
| Description: | The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so. |
