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 maximum CGTase activity obtained on SC was 1,155 U mL(-1) under aerobic conditions. 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.

First starch is liquified either by heat treatment or using α-amylase, then CGTase is added for the enzymatic conversion. The industrial production of CGTase was made attractive only when alkaliphilic Bacillus species were introduced as producing organism (23).

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). 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.
