“…Moreover, dermis free from interfibrous proteins becomes more permeable, it volume is formed, and tannin diffusion into the dermis is accelerated. As regards bioresistance, the liming process is characterized by the fact that asporous bacteria die in the lime bath and the sporous ones stop growing and propagating [11].…”

“…Mono- and disaccharides are characterized by tautomerism and diastereoisomerism, e.g., besides chain-cyclic tautomerism of glucose, there are eight pairs of its diastereomers. The tautomers and diastereomers (stereoisomers not related as mirror images) are characterized by different physicochemical properties [36, 37]. This can affect the carbonization results for saccharides.…”

Structural Features of Carbons Produced Using Glucose, Lactose, and Saccharose

Glucose, lactose, and saccharose were used as precursors to prepare chars at 400 °C then activated at 800 °C or 1000 °C in closed vessels with controlled amounts of oxygen penetrating through nanopores in the vessel walls. There are correlations between the porosity, amounts of residual O- and H-containing functionalities, and electroconductivity of amorphous carbons studied. The pore size distributions calculated using the nitrogen adsorption isotherms and TEM images show that all carbons are mainly nanoporous with certain contribution of narrow mesopores (at pore half-width x < 5 nm). Oxidizing activation by oxygen penetrating into the closed vessels with chars through nanopores can more strongly change the outer layers of char particles than the inner pores. Therefore, despite relatively great burn-off degree, the textural characteristics are relatively low for activated carbons.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-016-1723-z) contains supplementary material, which is available to authorized users.

“…Absolute specificity of an enzyme for only one substrate is rare and there may be several monosaccharides present in a sample which can be acted on to varying degrees by the same enzyme (Bochkov et al , 1991). For example, cellulose hydrolyses 1,4‐b, D‐glucosidic linkages in cellulose, lecithin and cereal b‐D‐glucans (Yong and Kai, 1999).…”

“…Whereby the presence of other sugars are almost similar in terms of amount compared to the hydrolysates with amylase, deoxy derivatives contain one less oxygen atom than the monosaccharide from which they are derived. 2‐Deoxyribose is a most important deoxy pentose and is a major constituent of deoxyribonucleic acid (Bochkov et al , 1991).…”

PurposeThe aim of this study is to identify and quantify sugar and polysaccharide contents in locally grown Hericium erinaceus.Desig/methodolog/approachThe experiment is presented of chromatography methods to determine sugars in Malaysian–grown H. erinaceus. After the extraction, the crude polysaccharide solution was followed by hydrolysis with acid as well as enzymes reaction, respectively.FindingsIn thin–layer chromatography, two sample spots turned blue after treatment with sugar visualizing reagent. The HPLC analysis of the H. erinaceus hot water crude extract showed arabinose as the major component. All H. erinaceus water crude extract showed the components of arabinose, glucose and rhamnose when reacting with different enzymes. The ratio of arabinose and glucose was 2.3:1 after enzymatic reaction compared with 2.7:1 before the enzymatic reaction.Research limitation/implicationsThe H. erinaceus polysaccharides from the fruiting body can be further isolated and purified by means of GCMS. In this way, the contents of the polysaccharides isolated and types of the linkage can be determined thoroughly in a more detailed way. The purified polysaccharides also should be screened for the bioassay guide fractionation.Practical implicationsThe H. erinaceus can also be analyzed for its various nutritional values. In this way, it is hoped that Malaysia can produce Hericium products locally for the benefit of the local consumers with a more competitive price.Originalit/valueThis paper fulfils an identified information of sugar and polysaccharide content in Malaysian–grown H. erinaceus.
