- Efficient biocatalytic production of cyclodextrins by combined action of amylosucrase and cyclodextrin glucanotransferase (2016), J. Agric. Food Chem., 64, 4371-4375 .
Application
| Application | Comment | Organism |
|---|---|---|
| food industry | cyclodextrins are frequently utilized chemical substances in the food, pharmaceutical, cosmetics, and chemical industries. An enzymatic process for cyclodextrin production is developed by utilizing sucrose as raw material instead of corn starch. Cyclodextrin glucanotransferase from Paenibacillus macerans is applied to produce the cyclodextrins from linear alpha-(1,4)-glucans, which are obtained by Neisseria polysaccharea amylosucrase treatment on sucrose. The greatest cyclodextrin yield (21.1%, w/w) is achieved from a one-pot dual enzyme reaction at 40°C for 24 h. The maximum level of cyclodextrin production (15.1 mg/ml) is achieved with 0.5 M sucrose in a simultaneous mode of dual enzyme reaction, whereas the reaction with 0.1 M sucrose is the most efficient with regard to conversion yield. Dual enzyme synthesis of cyclodextrins is successfully carried out with no need of starch material. Efficient bioconversion process that does not require the high temperature necessary for starch liquefaction by thermostable alpha-amylase in conventional industrial processing | Paenibacillus macerans |
