Abstract
High-purity lactulose is mandatory for its medical uses and food applications. This work developed an efficient lab-scale strategy for the synthesis of high-purity lactulose by combining lactose-to-lactulose isomerization with simultaneous recovery of lactulose, which was conducted concurrently and semi-continuously in a boronate affinity adsorbent-packed column. The first step covers the boronate affinity adsorbent-based adsorption-assisted lactose-to-lactulose isomerization. Under optimized conditions, in situ selectively binding of the newly formed lactulose onto the boronate affinity adsorbent enables a much-enhanced lactulose yield up to 80.20% with the lowest byproducts yield of 6.30%. Afterward, over 90% of the adsorbed lactulose can be recovered through sequential desorption with purity >98%. The net outcome of the applied strategy was the yield of high-purity lactulose up to 72.31%, the highest value ever reported. Moreover, the packed column displayed excellent operational stability. The encouraging results validate the high potential of this approach in the sustainable production of high-purity lactulose.

Abstract
Lactulose, a semisynthetic nondigestive disaccharide with versatile applications in the food and pharmaceutical industries, has received increasing interest due to its significant health-promoting effects. Currently, industrial lactulose production is exclusively carried out by chemical isomerization of lactose via the Lobry de Bruyn-Alberda van Ekenstein (LA) rearrangement, and much work has been directed toward improving the conversion efficiency in terms of lactulose yield and purity by using new chemo-catalysts and integrated catalytic-purification systems. Lactulose can also be produced by an enzymatic route offering a potentially greener alternative to chemo-catalysis with fewer side products. Compared to the controlled trans-galactosylation by β-galactosidase, directed isomerization of lactose with high isomerization efficiency catalyzed by the most efficient lactulose-producing enzyme, cellobiose 2-epimerase (CE), has gained much attention in recent decades. To further facilitate the industrial translation of CE-based lactulose biotransformation, numerous studies have been reported on improving biocatalytic performance through enzyme mediated molecular modification. This review summarizes recent developments in the chemical and enzymatic production of lactulose. Related catalytic mechanisms are also highlighted and described in detail. Emerging techniques that aimed at advancing lactulose production, such as the boronate affinity-based technique and molecular biological techniques, are reviewed. Finally, perspectives on challenges and opportunities in lactulose production and purification are also discussed.

Abstract
A novel approach for the synthesis of epoxybutane via decarboxylation of butenyl carbonate derived from butanediol was developed for the first time. For the carbonylation of butanediol with dimethyl carbonate, NaAlO2 has exhibited excellent catalytic activity under mild reaction conditions. The yield of butenyl carbonate reached as high as 96.2%. NaAlO2 provides suitable acid-base active sites to promote the transesterification reaction of butanediol and dimethyl carbonate. For the following step of decarboxylation of butenyl carbonate, ionic liquid 1-butyl-3-methylimidazolium bromide could effectively catalyze the decarboxylation process both in batch or continuous processes. Moreover, the catalytic mechanism for the crucial step of decarboxylation of butenyl carbonate over 1-butyl-3-methylimidazolium bromide was explored using DFT calculations. The results showed that the electrostatic and hydrogen-bond effects of 1-butyl-3-methylimidazolium bromide played a crucial role for the generation of epoxybutane. Briefly, the Br anion of the ionic liquid attacks the methylene of the ring and the H of the ionic liquid cation attacks the carbonyl oxygen, which facilitated the five-ring opening and subsequent decarboxylation to form BO. This study not only provided a new and green synthetic route for producing epoxybutane, but also contributed to the effective utilization of butanediol, which is inevitably produced as by-product in the process of coal to ethylene glycol, suggesting a promising application in the clean manufacture of epoxybutane with inexpensive cost.

Abstract
BACKGROUND Lactulose, a valuable lactose-originated 'bifidus factor' product, is exclusively produced by chemical-based isomerization commercially. A complexing agent of sodium aluminate exhibiting high conversion efficiency and strong recyclable stability is more practical for industrial applications. In this study, efficient purification of high-purity lactulose through recycling of sodium aluminate and further desalination by nanofiltration (NF) was implemented on a pilot scale. RESULTS Over 99.5% of the catalyst was prior recycled in the form of Al(OH)3 precipitate by pH-induced precipitation and centrifugation; residual aluminum was further absorbed by ion exchange resin to an acceptable level (≤10 mg kg-1 ). Subsequently, impurities (monosaccharides and NaCl) were ideally separated from lactulose syrup by NF based on their significant retention differences (lactulose 94.8-97.2% > lactose 86.2-93.5% > monosaccharides 36.3-48.7% > NaCl 9.5-31.1%). High-purity (>95%) lactulose was obtained with >90% yield in both constant and variable volume diafiltration (CVD and VVD) modes when the volume dilution ratio (Vc /Vf ) was 4.0 and 2.5 respectively. Both experimental and predicted results showed that the VVD mode was more water-saving in practice. CONCLUSION This is the first trial purification of lactulose syrup from chemical isomerization of lactose catalyzed by sodium aluminate, and the applied methodology is a promising industrial-scale purification strategy. © 2018 Society of Chemical Industry.

Abstract
Boronate affinity materials have been widely used for enrichment of cis-diol molecules. In this work, phenylboronic acid functionalized adsorbents were prepared via a simple and efficient procedure grafting phenylboronic acid groups onto amino macroporous resins. Elemental analysis has confirmed the successful functionalization of AR-1M and AR-2M with approximately 2.17% and 0.73% weight percentage of boron. Comparatively, AR-1M possessed higher lactulose adsorption capacity ( qe-Lu, 84.78 ± 0.95 mg/g dry resin) under neutral conditions (pH = 7), while the introduced glutaraldehyde spacer arms on AR-2M resulted in excellent adsorption selectivity (α ≈ 23), high adsorption efficiency (π ≈ 22%), and fast adsorption/desorption rate. The purity of lactulose (PuDLu) through pH-driven adsorption (pH 7-8) and desorption (pH 1.5) can be effectively improved depending on the ratio of lactulose to lactose. When lactulose/lactose ≥ 1:1, PuDLu ≈ 95% was achieved. No significant drop in qe-Lu (>90%) was observed after ten-consecutive repeats. Results demonstrated that the newly developed method may achieve satisfactory performance in lactulose purification.

Abstract
The AGE superfamily (AGEs) is made up of kinds of isomerase which are very important both physiologically and industrially. One of the most intriguing aspects of AGEs has to do with the mechanism that regulates their activities in single conserved active pocket. In order to clarify the relationship among single conserved active pocket and two activities in AGEs, results for the epimerization activity catalyzed by RaCE and the isomerization activity catalyzed by SeYihS were obtained by using QM/MM umbrella sampling simulations and 2D-FES calculations. Our results show that both of them have similar enzyme-substrate combination mode for inner pyranose ring in single conserved active pocket even though they have different substrate specificity. This means that the pathways of ring opening catalyzed by them are similar. However, one non-conserved residue (Leu183 in RaCE, Met175 in SeYihS) in the active site, which has different steric hindrance, causes a small but effective change in the direction of ring opening in stage 1. And then this change will induce a fundamentally different catalytic activity for RaCE and SeYihS in stage 2. Our results give a novel viewpoint about the regulatory mechanism between CE and YihS in AGEs, and may be helpful for further experiments of rational enzyme design based on the (α/α)6-barrel basic scaffold.
