Abstract
In this study, the production of isomaltooligosaccharide from potato peel starch was carried out in three steps: liquefaction, saccharification, and transglucosylation. Further, cloning α-transglucosidase gene from Aspergillus niger (GH31 family), transforming into E. coli BL21 (DE3), overexpressing and purifying the resulting protein for the production of α-transglucosidase. The generated α-transglucosidase was then bound with magnetic nanoparticles, which improved reusability up to 5 cycles with more than 60% activity. All the modifications were characterized using the following methods: Fourier transform infra-red analysis, Transmission Electron Microscopy, Field Emission Scanning Electron Microscopy, Energy Dispersive X-ray spectroscopy, X-Ray Diffraction Spectroscopy, Thermogravimetric Analysis, and Dynamic Light Scattering (DLS) analysis. Further, the optimum conditions for transglucosylation were determined by RSM as follows: enzyme-to-substrate ratio 6.9 U g-1, reaction time 9 h, temperature 45 °C, and pH 5.5 with a yield of 70 g l-1 (± 2.1). MALDI-TOF-MS analysis showed DP of the IMOs in ranges of 2-10. The detailed structural characterization of isomaltooligosaccharide by GC-MS and NMR suggested the α-(1 → 4) and α-(1 → 6)-D-Glcp residues as major constituents along with minor α-(1 → 2) and α-(1 → 3) -D-Glcp residues.

Abstract
We explored the ability of an Aspergillus niger α-glucosidase displayed on P. pastoris to act as a whole-cell biocatalyst (Pp-ANGL-GCW61) system to synthesize isomalto-oligosaccharides (IMOs). IMOs are a mixture that includes isomaltose (IG2), panose (P), and isomaltotriose (IG3). In this study, the IMOs were synthesized by a hydrolysis-transglycosylation reaction in an aqueous system of maltose. In a 2 mL reaction system, the IMOs were synthesized with a conversion rate of approximately 49% in 2 h when 30% maltose was utilized under optimal conditions by Pp-ANGL-GCW61. Additionally, the 0.5-L reaction system was conducted in a 2-L stirred reactor with a conversion rate of approximately 44% in 2 h. Moreover, the conversion rate was relatively stable after the whole-cell catalyst was reused three times. In conclusion, Pp-ANGL-GCW61 has a high reaction efficiency and operational stability, which makes it a powerful biocatalyst available for industrial scale synthesis.
