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. From our findings, low concentration of tapioca starch (1% w/v) gives higher CGTase production. Illias et al 24 reported maximum CGTase production with 1% tapioca starch as the carbon source for Bacillus sp.

In this study, we report the This book deals with Production of cyclodextrin glucanotransferase (CGTase) from Bacillus subtilis isolated from agriculture field soil samples. Initial screening This book deals with Production of cyclodextrin glucanotransferase (CGTase) from Bacillus subtilis isolated from agriculture field soil samples.

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). The US132 CGTase production monitored after 18 hours of induction showed that the use of M9ZB and 2TY medium increased the production by about 1.1-fold (16.5 U/mL) and 1.3-fold (20 U/mL), respectively, in comparison to that obtained by LB broth. However, the use of M9 medium decreased the production to attain only 8 U/mL.

29 Dec 2012 The production of CGTase using lactic acid bacterium is an attractive alternative and safer strategy to produce CGTase. In this study, we report the

of Initial pH on CGTase Production BACKGROUND. High‐purity α‐, β‐, or γ‐cyclodextrin (CD) production using cyclodextrin glycosyltransferase (CGTase) as biocatalyst to cyclize starch is advantageous owing to its low cost of purification and product specificity. Several approaches have been investigated to enhance product specificity of CGTase, such as new CGTase isolation, CGTase 2007-09-22 · Cyclodextrins are cyclic α-1,4-glucans that are produced from starch or starch derivates using cyclodextrin glycosyltransferase (CGTase).

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.

The incubation was done at 37ºC, 200 rpm and aeration 1.5 vvm. 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%. Molecular weight of the optimization using experimental design.

CGTase Production The CGTase production pattern by isolated Bacillus sp. 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). It was evident from the results production and microbial growth (10 & 11).

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.

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. Our work revealed that CGTase could inhibit the growth of V. dahliae, activate innate im- Crude CGTase production was observed to be maximum after 28 h incubation at 37 o C with CGTase activity reading 19 U/ml.

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,

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 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.
