As evident from Table 11, it was revealed that the alpha-isomaltosylglucosaccharide-forming enzyme well acted on saccharides having a glucose polymerization degree of at least three and having a maltose structure at their non-reducing ends, among the saccharides tested. It was also found that the enzyme slightly acted on saccharides, having a glucose polymerization degree of two, such as maltose, kojibiose, nigerose, neotrehalose, maltotriitol, and erlose.
With water; calcium chloride;CMM-forming enzyme; at 40℃; for 24.0h;pH 6.0;Aqueous acetate buffer; Enzymatic reaction;Reactivity (does not react); Substrate specificity of CMM-forming enzyme of the present invention was investigated using various saccharides as substrates. Substrate solutions were prepared by dissolving maltose, maltotriose, maltotetraose, maltopentaose, maltohexaose, maltoheptaose, neotrehalose, trehalose, kojibiose, nigerose, isomaltose, isomaltotriose, panose, isopanose, maltitol, maltotriitol, alpha-, beta-, or gamma-cyclodextrin, amylose, soluble starch, glycogen, pullulan or dextran into water. Each substrate solution was admixed with acetate buffer (pH 6.0) and CaCl2 to give final concentrations of 20 mM and 1 mM, respectively. Then, each resulting substrate solution was further admixed with one unit/g-substrate, on a dry solid basis, of the purified preparation of CMM-forming enzyme, obtained by the method in Experiment 4. Substrate concentration was set to 2% (w/v) and followed by the enzyme reaction at 40C and pH 6.0 for 24 hours. Action and the specificity of the enzyme on these saccharides were confirmed by analyzing the reaction mixture before and after the reaction by TLC described in Experiment 1. The results are in Table 5; As is evident from the results in Table 5, CMM-forming enzyme of the present invention acts on maltotetraose, maltopentaose, maltohexaose, and maltoheptaose, and slightly on maltotriose among saccharides tested. Further, CMM-forming enzyme of the present invention acts on amylose, starch, and glycogen. From the results, it was revealed that the enzyme acted on alpha-1,4 glucans having a glucose polymerization degree of 3 or higher.

93% With iodine; at 50℃; for 0.166667h;Microwave irradiation; General procedure: To a 10.0 mL round bottom flask, D-glucose (2.0 mmol) and acetic anhydride (12.0 mmol, 1.2 equiv. per OH) in the IL400 (2.0mL) was added I2 (0.05 mmol) at room temperature. Then themixture was heated to 50 C under MW irradiation (200 W) until the TLC analysis showed that the reaction was complete.Then the reaction mixture was cooled to room temperature,and toluene (2.0 mL × 3) was added. The mixture was vigorously stirred for several minutes and then kept stationary. The upper toluene layer containing the product was collected. Toluene was removed by a rotary evaporator, and the crude product was purified by recrystallization in ethyl alcohol. The desired peracetylated sugars were obtained in 90%-99% yields. The bottom phase was the ionic liquid containing the I2 catalyst and produced acetic acid. The I2/IL400 system was reused after the removal of the acetic acid under reduced pressure.

With hydrogen In water at 99.84℃; for 4h; Autoclave; 2.3. Catalytic performances test General procedure: The liquid-phase hydrogenation of sugar was performed at 4.0 MPaof H2 pressure and 373 K in a 200-mL stainless steel autoclave with aTeflon tube to avoid metal contamination, in which 0.5 g of Ni catalystand a sugar aqueous solution (10 wt.% in 50 mL H2O) were well mixed.According to the drop of the H2 pressure in the autoclave within 10min, both the specific activity (the H2 uptake rate per gram of Ni, RHm,mmol h-1 gNi-1) and the intrinsic activity (the H2 uptake rate per m2 ofNi, RHS, mmol h-1 mNi-2) were calculated by using the ideal gasequation. The reaction mixture was sampled at intervals for productanalysis through a liquid-phase chromatograph (Agilent 1200)equipped with a carbohydrate column (Shodex, SC1011) and a refractiveindex detector at 333 K with water as movable phase at 0.50mL min-1. Preliminary kinetic studies revealed that there was a plateauin the dependency of the reaction initial rate upon the stirring rateabove 1000 rpm and that the reaction initial rate varied linearly withcatalyst amount from 0.1 to 1.0 g, indicating that the stirring rate of1200 rpm was high enough that the hydrogenation rates were independentof mass transfer. After cooling to room temperature at theend of the reaction, the catalyst was separated by centrifugation andwashed with deionized water for further characterizations and applications.In order to determine the catalyst durability, the used catalystwas centrifuged and washed thoroughly with distilled water after eachrun of the reaction. Then, the used catalyst was reused with freshcharge of sugar for subsequent recycle runs under same reaction conditions.
