G1. Organism, CGTase Production, and Puric ation. e CGTase producing organism used in this study was isolated from native soil in our laboratory as described by Park et al. . is natural bacterial isolate was identi ed and depositedas Microbacteriumterrae MTCC atIMTECH, Chandigarh, India . CGTase production was carried out using mL Production of CGTase by B. circulans P28 in 2 L stirred tank bioreactor increased propotionally with the increase in agitation speed, ranging from 400 to 900 rpm though growth was slightly inhibited at agitation speed of above 600 rpm. The analysis of production of CDs from 1% soluble starch by the wild-type CGTase and its mutants at pH 7.5 showed that higher γ-CD–forming activity leads to greater γ-CD production. In the case of the A223H, A223K and A223R mutants, the γ-CD production increased but there was little change in the β-CD production.

Abstract. The cyclodextrin glycosyltransferase (CGTase) is an important enzyme for cyclodextrin (CD) production, and is also widely used in the biotechnology, food, and pharmaceuticals industries. Secretory CGTase production by recombinant Komagataella phaffii using defined medium is a promising approach because of low cost, less impurity protein. CGTase overexpression enabled a burst of reactive oxygen species production and activated pathogenesis-related gene expression, indicating that the transgenic cotton was better prepared to protect itself from infection.

Production of a novel cyclodextrin glycosyltransferase (CGTase) from Klebsiella pneumoniaeAS‐22 strain, which converts starch predominantly to α‐CD at high conversion yields, in batch, fed‐batch, and continuous cultures, is presented. 2011-04-27 · High-level production of α-cyclodextrin glycosyltransferase (CGTase) is one of the key factors in α-cyclodextrin (CD) preparation. In the present study, a fed-batch fermentation strategy for high-cell-density cultivation of Escherichia coli and the extracellular production of recombinant α-CGTase from Paenibacillus macerans JFB05-01 was established. 2016-05-05 · CGTase activity showed that, CGTase production varied with variation in initial Inoculum level ( Fig:2 ). A maximum enzyme production of 24.73 U/ml and specific activity 8.49 U/mg was observed in 4% initial inoculum supplemented conditions.

Molecular weight of the optimization using experimental design. Enz. Cyclodextrin glycosyltransferases (CGTases) are widely used in starch deep processing, so reducing their cost by improving their production is of significant industrial interest. The CGTase from Bacillus stearothermophilus NO2 possesses excellent catalytic properties but suffers from low production in E. coli.
First, using glucose‐based feed to increase cell density, followed by starch‐based feed to induce enzyme production, resulted in high cell density of 76 g dry cell weight/L, although the CGTase production was low. The CGTase from Bacillus stearothermophilus NO2 possesses excellent catalytic properties but suffers from low production in E. coli. In this study, directed evolution was used to create three point mutants (I631T, I641T and K647E) that were produced in E. coli with shake-flask yields 1.7-, 2.1-, and 2.2-fold higher than that of wild-type
The concentration of yeast extract in the medium is the most important variable for production of CGTase because it is rich in amino acids, trace elements and inorganic salts 26.The combination with 1.5% was used to achieve high CGTase activity at shorter period of cultivation. A low level (0.75%) of nitrogen source was also reported as the
CGTase from B. macerans initially favors α-CD production; only in later stages of the reaction does the yield of β-CD approximate or exceed that of its α-homolog.

Production of cyclodextrin glycosyltransferase (CGTase) is influenced by the reaction of the CGTase-producing strain towards various types of substrates. Variations in environmental factors such as concentrations of carbon and nitrogen sources possess significant effects on CGTase production. production of CGTase, different parameters such as incubation periods (0-72 h), medium pH (9, 9.5, 10, 10.5, 11 and 11.5) and temperature (28ºC, 32ºC, 37ºC, 42ºC, 47ºC and 52ºC) were used.
