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.

Cyclodextrin glucanotransferase (CGTase, EC 2.4.1.19) production using new alkaliphile Microbacterium terrae KNR 9 was investigated by submerged fermentation. Statistical screening for components belonging to different categories, namely, soluble and raw starches as carbon sources, complex organic and inorganic nitrogen sources, minerals, a buffering agent, and a surfactant, has been

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. 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 effects of reaction conditions on cyclodextrins (CDs) production by CGTase from newly isolated Bacillus agaradhaerens KSU-A11 is reported. Among six

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.

Enz. 2009-07-08 · CGTase productionThe experiments were made using a CGTase from B. circulans DF 9R, isolated from rotten potatoes and purified by affinity chromatography on α-CDs coupled to Sepharose-4B . The microorganism was cultured in a minimum saline medium for enzyme production as described in a previous report . 2.3.

Cyclodextrin glucanotransferase (CGTase, EC 2.4.1.9) is an unique enzyme capable of converting starch and related substrates into cyclodextrins (CDs). In this paper, we report an one step gel purification method of CGTase from Bacillus sp. and later enzyme characterization. The Bacillus sp. strain was isolated from a Colocacia esculenta rizospheric soil sample and the CGTase production was In view of this, effect of tapioca starch on CGTase production by the alkalophile was evaluated.

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 activity (circle), pH (triangle) and total reducing sugars concentration (square) versus time for enzyme production with immobilized Bacillus firmus strain 37 on bone charcoal.

cyclized by CGTase to produce CD. (Biwer et al. conditions. CGTase producing bacteria can be found tried to optimize the CGTase production. Among the

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. MATERIALS AND METHODS First starch is liquified either by heat treatment or using α-amylase, then CGTase is added for the enzymatic conversion. CGTases produce mixtures of cyclodextrins, thus the product of the conversion results in a mixture of the three main types of cyclic molecules, in ratios that are strictly dependent on the enzyme used: each CGTase has its own characteristic α:β:γ synthesis ratio. [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.

Crude CGTase production was observed to be maximum after 28 h incubation at 37 o C with CGTase activity reading 19 U/ml. The enzyme production was shown to be growth associated and maximum CGTase production was detected during the decline phase. The effect of nutritional requirements on the CGTase production was carried out in this study.

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. TS1-1: Media fold with a yield of 55.14%.
