| additional information | preparation of the AglU-displaying Pichia pastoris whole-cell biocatalyst for optimized synthesis of isomaltooligosaccharides (IMOs). IMOs are a mixture that includes isomaltose (IG2), panose (P), and isomaltotriose (IG3). The recombinant Aspergillus niger enzyme expressed from Pichia pastoris has a high reaction efficiency and operational stability, method optimization and evaluation, overview. IMOs synthesis by transglycosylation, best at pH 4.0 and 55-60°C | Aspergillus niger |
