Cyclodextrin glucanotransferase (CGTase) was produced when the Bacillus sp. TS1-1 was grown in a medium containing sago starch, yeast extract, phosphorus and mineral salt sources, using shake flask mode at 37 °C for 24 h.

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.

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. The influence of various carbon and nitrogen sources for the maximum production of CGTase production was studied. The carbon sources Effect of concentration of C, N and sodium carbonate: The effect of different concentration of sago starch on CGTase production was observed. As observed from Table 3, a significantly high CGTase production was achieved in medium containing 0.1 and 1% (w/v) sago starch while significantly low enzyme was detected in medium without any supplementation of sago starch.

Conclusion: The genotoxicity assays and repeated dose toxicity study support the safe use of CGTase in production of alpha-glycosyl isoquercitrin.

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.

Conclusion: The genotoxicity assays and repeated dose toxicity study support the safe use of CGTase in production of alpha-glycosyl isoquercitrin. Engineering CGTase to improve synthesis of alkyl glycosides.

There are several known alkaliphilic Bacillus sp. that are able to produce CGTase. Keywords: Cyclodextrin glycosyltransferase. (CGTase), alkaliphile, tapioca

The enzyme cyclodextrin glycosyltransferase (CGTase), used for production of cyclodextrins, is entering the club of industrial enzymes such as proteases, As all known wild-type CGTases produce a mixture of α-, β-, and γ-cyclodextrins, the obtaining of a. CGTase predominantly producing γ-cyclodextrin is dis-. In this work, the CGTase produced by Bacillus clausii strain E16 was used to produce CD from maltodextrin and different starches (commercial soluble starch, Cyclodextrin glucanotransferase (CGTase) is an enzyme that convert starch into cyclodextrin (CD) by transglycosylation reaction. The CD has been used in 16 Oct 2019 Structure basis of a mutant a-CGTase tyrosine167histidine from Bacillus sp.

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. CGTase production was the same with either organic nitrogen or inorganic nitrogen source.

The carbon sources In enzymology, a cyclomaltodextrin glucanotransferase (also cyclodextrin glycosyl transferase or CGTase for short) (EC 2.4.1.19) is an enzyme that catalyzes the chemical reaction of cyclizing part of a 1,4-alpha-D-glucan molecule through the formation of a 1,4-alpha-D-glucosidic bond. Immobilisation of CGTase for continuous production of long-carbohydrate-chain alkyl glycosides Control of product distribution by flow rate adjustment. / Svensson, David; Adlercreutz, Patrick.

[10] CGTase production The selected strain was cultivated in flasks containing 200 mL of culture medium and incubated at 37ºC during 18 hours at 200 rpm. This culture was used to inoculate (10% V/V) 2L of culture medium, in a fermentator (5 L capacity) containing 2 mL of antifoaming agent. The incubation was done at 37ºC, 200 rpm and aeration 1.5 vvm.

2004-10-06 · Typically modes of CGTase production will be conducted initially using shake flask culture and submerge fermentation utilizing selective. Various types of medium composition mainly carbon and nitrogen source concentration, inoculums size, pH and temperature for fermentation production of CGTase had been studied in several published paper [4] , [9] , [23] .

The influence of various carbon and nitrogen sources for the maximum production of CGTase production was studied. The carbon sources Effect of concentration of C, N and sodium carbonate: The effect of different concentration of sago starch on CGTase production was observed. As observed from Table 3, a significantly high CGTase production was achieved in medium containing 0.1 and 1% (w/v) sago starch while significantly low enzyme was detected in medium without any supplementation of sago starch. The enzyme production was further improved by two fed‐batch approaches. 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.
