Kinetics of maltooligosaccharide hydrolysis in subcritical water

The kinetics of the hydrolysis of maltooligosaccharides with a degree of polymerization (DP) of 3-6 in subcritical water was studied using a tubular reactor at temperatures between 200 and 260°C and at a constant pressure of 10 MPa. The maltooligosaccharide disappearance and product formation at residence times shorter than 50 s could be expressed by first-order kinetics. The rate constants for the hydrolysis of each maltooligosaccharide were evaluated. There was a tendency that the exo-site glucosidic bond was hydrolyzed faster than the endo-site one irrespective of the DP of the maltooligosaccharide. The hydrolysis of the maltooligosaccharides was consecutively preceded, and the time dependence of the hydrolysis for maltooligosaccharides with different DPs could be calculated by simultaneously solving the mass balance equations for all the possible saccharides.

Molecular cloning and functional expression of a new amylosucrase from Alteromonas macleodii

The presence of amylosucrase in 12 Alteromonas and Pseudoalteromonas strains was examined. Two Alteromonas species (Alteromonas addita KCTC 12195 and Alteromonas macleodii KCTC 2957) possessed genes that had high sequence homology to known amylosucrases. Genomic clones containing the ASase analogs were obtained from A. addita and A. macleodii, and the deduced amino acid sequences of the corresponding genes (aaas and amas, respectively) revealed that they were highly similar to the ASases of Neisseria polysaccharea, Deinococcus radiodurans, and Deinococcus geothermalis. Functional expression of amas in Escherichia coli was successful, and typical ASase activity was detected in purified recombinant AMAS, whereas the purified recombinant AAAS was nonfunctional. Although maximum total activity of AMAS was observed at 45 °C, the ratio of transglycosylation to total activity increased as the temperature decreased from 55 to 25 °C. These results imply that transglycosylation occurs preferentially at lower temperatures while hydrolysis is predominant at higher temperatures.
