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.

The CGTase production was further studied with the optimized process parameters on submerged cultivations (SC) and solid-state cultivations (SSC) using soybean industrial fibrous residue (SIFR). The maximum CGTase activity obtained on SC was 1,155 U mL(-1) under aerobic conditions. CGTases are produced by a variety of bacteria, mainly Bacillus species, by submerged culture in complex medium. CGTases differ in the amount and types of CDs produced. In addition, CGTase production is highly dependent on the strain, medium composition and culture conditions. Extracellular production of CGTase is usually achieved by expression in the native Bacillus host or by targeting the protein to the periplasmic space followed by release to the extracellular medium through the weakening of E. coli cell envelope.

Cgtase production

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. The influence of various carbon and nitrogen sources for the maximum production of CGTase production was studied. The carbon sources Production of cyclodextrin glucanotransferase CGTase production. CGTase was purified around 20.21 (CGTase) from alkalophilic Bacillus sp.

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. The influence of various carbon and nitrogen sources for the maximum production of CGTase production was studied. The carbon sources

and Bacillus circulance was investigated by growing cultures in soluble starch based medium and determining the CGTase enzyme activity in cell free culture broth at regular intervals during the growth phase (Fig. 1).

expression in Escherichia coli Cyclodextrin glucanotransferase (CGTase) is used for catalytic production of cyclodextrins and various glycosylated products.

This mini-review focuses on the enzymatic production, unique properties, and applications of γ-cyclodextrin as well as its difference with α- and β-cyclodextrins. As all known wild-type CGTases CGTase production was the same with either organic nitrogen or inorganic nitrogen source. CGTase activity decreased 2-fold when incubation temperature was increased from 28 to 37 °C, and decreased 2.1- fold when the initial pH was lowered from 10.3 to 7.4.

CGTase activity (circle), pH (triangle) and total reducing sugars concentration (square) versus time for enzyme production with immobilized Bacillus firmus strain 37 on bone charcoal. Influence of Sodium ion production of CGTase Liquid medium described by Nakamura and Horikoshi (18) was added of 1% Na 2CO 3 to raise the pH to 10. In order to verify the effect of sodium ion on the CGTase production strains were grown in the same medium replacing Na 2CO 3 by NaCl, at pH 7.0. Qualitative analysis of CGTase The CGTase production process consists of a submerged culture fermentation using the recombinant producer organism Bacillus licheniformis strain SJ1608, the stock culture and fermentation culture both being controlled frequently for identity of the organism, absence of contaminating microorganisms, and enzyme yield before harvesting the enzyme. The 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 alpha-cyclodextrin (alpha-CD) and n-dodecyl-(1,4)-beta-maltopyranoside (C(12)G(2)beta).

These torus 25 Oct 2010 convert starch and related substrates into cyclodextrins.

It was evident from the results production and microbial growth (10 & 11). Numerous strategies like computational techniques and genetic engineering are also used to enhance the production of CGTase (6, 8 & 11). This study presents the screening of Bacillus flexus MSBC 2, which is a potent producer of CGTase and the optimization of CGTase production by E. coli In these experiments, we assessed the effect of increas-ing concentrations (0–10 mM) of β-cyclodextrin on the production of soluble γ-CGTase. β-Cyclodextrin was used because it is cheap and readily available, and it ef-fectively promotes the production of soluble γ-CGTase.

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 industrial production of CGTase was made attractive only when alkaliphilic Bacillus species were introduced as producing organism (23). This paper reports the production optimization and some biochemical properties of a CGTase produced by a strain of Bacillus licheniformis isolated from cassava culture soil. 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.
