“…From 1 H NMR data presented in Table 4, the polymerization conversion rate of poly(ethylene adipate) (Scheme A') was twice higher than that of poly(ethylene succinate) (Scheme B'). This can be attributed to the alkyl chain length selectivity of lipases, which presented higher activity towards long alkyl chain substrate, dimethyl adipate, than towards dimethyl succinate [30,31]. 1 H NMR data of poly(ethylene adipate) (Scheme A') ( Fig.…”

Several polyesters were synthesized from ethylene glycol, glycerol and adipate, succinate dimethyl esters. Immobilized Candida antarctica lipase B was used as catalyst for 6 h under vacuum at 70°C without any further solvents. The highest conversion rate of 88.5% occurred for the polymerization of poly(ethylene adipate), evaluated by 1 H NMR. MALDI-TOF analysis indicated that most of the oligomers formed were dimers or trimers. After successfully synthesize the polyesters we setup the optimal conditions for their in-situ coating onto cotton substrates with a soluble lipase from Thermomyces lanuginosus. This work presents a novel bio-approach to impart hydrophobic properties to coated cotton-based fibre materials.

“…Enzymatic esterification of cotton and Avicel cellulose was also achieved with wild‐type and engineered cutinase (fused with the carbohydrate binding module N1 of the endoglucanase C (CenC) from Cellulomonas fimi ) from Fusarium solani pisi , either in isooctane with octanoic acid or in edible vegetable oil [44] . Xiaoman and collaborators developed a different approach: cutinase from Thermobifida fusca and triolein were pre‐adsorbed on cotton and the reaction proceeded in a dry state, obtaining a significant increase of hydrophobicity [45] …”

Enzymatic Modification of Cellulose To Unlock Its Exploitation in Advanced Materials

Nowadays natural biopolymers have a wide variety of uses in various industrial applications, such as food, adhesives and composite materials. Among them, cellulose has attracted the interest of researchers due to its properties: high strength and flexibility, biocompatibility and nontoxicity. Despite that, in many cases its practical use is limited because of poor solubility and/or an unsuitable hydrophilic/hydrophobic balance. In this context, enzymatic modification appears as a powerful strategy to overcome these problems through selective, green and environmentally friendly processes. This minireview discusses the different methods developed for the enzymatic modification of cellulose, emphasizing the type of reaction, the enzymes used (laccases, esterases, lipases, hexokinases, etc.), and the properties and applications of the cellulose derivatives obtained. Considering that cellulose is the most abundant natural polymer on Earth and can be derived from residual lignocellulosic biomass, the impact of its use in bio‐based process following the logic of the circular economy is relevant.

This review is the ninth update of the original article published in 1999 on the application of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry to the analysis of carbohydrates and glycoconjugates and brings coverage of the literature to the end of 2016. Also included are papers that describe methods appropriate to analysis by MALDI, such as sample preparation techniques, even though the ionization method is not MALDI. Topics covered in the first part of the review include general aspects such as theory of the MALDI process, matrices, derivatization, MALDI imaging, fragmentation and arrays. The second part of the review is devoted to applications to various structural types such as oligo‐ and poly‐saccharides, glycoproteins, glycolipids, glycosides and biopharmaceuticals. Much of this material is presented in tabular form. The third part of the review covers medical and industrial applications of the technique, studies of enzyme reactions and applications to chemical synthesis. The reported work shows increasing use of combined new techniques such as ion mobility and the enormous impact that MALDI imaging is having. MALDI, although invented over 30 years ago is still an ideal technique for carbohydrate analysis and advancements in the technique and range of applications show no sign of deminishing. © 2020 Wiley Periodicals, Inc.
