摘要:Abstract(#br)Co-expression of cyclodextrin glucanotransferase (CGTase) from Bacillus sp. G1 ( cgt ) with bacteriocin release protein (BRP) in Escherichia coli system resulted in the expression and excretion of the enzyme into the culture medium. The cultivation conditions were t...

摘要:... In the present study, recombinant Escherichia coli expressing cyclodextrin glucanotransferase (CGTase) was immobilized by adsorption and entrapment in a porous hollow fiber membrane. The effects of culture conditions (post induction time, agitation rate and pH) on CGTase...

摘要:Abstract Immobilized metal affinity chromatography (IMAC) was chosen as a method of purification for the recovery of CGTase from E. coli homogenate. E. coli harbouring the Bacillus sp. G1 gene expressed extracellularly secreted CGTase into ampicillin supplied LB broth. Culture wa...

摘要:Abstract(#br)Cyclodextrin glycosyltransferase (CGTase) catalyses the degradation of starch, producing α-, β-, and γ-cyclodextrins (CDs). Immobilized cells offer several advantages, such as their prolonged and repeated use, ease separation from the fermentation medium, and ...

摘要:Abstract(#br)A dynamic mathematical model was used in this study to describe the mass transfer and reaction kinetics of a fouled α–CGTase–CNF layer in a biocatalytic membrane reactor (BMR) system. BMR performance was evaluated based on the effect of substrate concentratio...

摘要:... The kinetic behaviour of the commercial enzyme Toruzyme® was studied with maltodextrin as substrate at different concentrations and for CGTase from Bacillus firmus strain 37 at a concentration of 100 g L−1. The mathematical model showed a proper ...

摘要:Abstract(#br)Bacillus macerans cyclodextrin glycosyltransferase (CGTase) (EC 2.4.1.19) was covalently immobilised on Eupergit C and used in a packed-bed reactor to investigate the continuous production of long-carbohydrate-chain alkyl glycosides from α-cyclodextrin (α-CD) and...

摘要:Abstract(#br)The study comparatively evaluated diverse strategic models of cyclodextrin (CD) production by the CGTase of Bacillus firmus strain 37: continuous production and repetitive batches in ultrafiltration systems; immobilization of CGTase on curdlan and vegetable spon...

摘要:Abstract(#br)In this study, two different approaches were assessed in order to direct the immobilization of a cyclodextrin glycosyltransferase on functionalized silica support, one by amino groups using glutaraldehyde activation (Si-NH-G-CGTase) and other by disulfide bond throu...
