Chats0
TLDR
Sucrose monolauroyl esters were found to serve as substrates for cyclodextrin glucanotransferase (CGTase)-catalyzed transglucosidation reactions, affording new sucrose esters that have an additional 1-3 glucose residues on the pyranose ring of the sucrose moiety in the ester.Abstract:

Immobilisation of CGTase for continuous production of long-carbohydrate-chain alkyl glycosides: Control of product distribution by flow rate adjustment
TL;DR: CGTase (Toruzyme 3.0 L) immobilised on Eupergit C had good operational stability at 60 and 70 degrees C thus showing the advantages of using more thermostable enzymes in biocatalysis, however, this enzyme was unsuitable for the production of C(12)G(8)beta due to extensive disproportionation reactions, giving a broad product range.
