Extractive Bioconversion of Gamma-Cyclodextrin and Recycling of Cyclodextrin Glycosyltransferase in Liquid Biphasic System Using Thermo-Separating Polymer

open access: yesFrontiers in Chemistry, 2018
An extractive bioconversion conducted on soluble starch with cyclodextrin glycosyltransferase (CGTase) enzyme in ethylene oxide-propylene oxide (EOPO)/potassium phosphates liquid biphasic system (LBS) to extract gamma-cyclodextrin (γ-CD) was examined.

Immobilized Cells of Bacillus circulans ATCC 21783 on Palm Curtain for Fermentation in 5 L Fermentation Tanks

open access: yesMolecules, 2018
Palm curtain was selected as carrier to immobilize Bacillus circulans ATCC 21783 to produce β-cyclodextrin (β-CD). The influence for immobilization to CGTase activity was analyzed to determine the operation stability.

ISOLAMENTO DE MICRORGANISMOS ALCALOFÍLICOS PRODUTORES DA ENZIMA CICLODEXTRINA GLICOSIL-TRANSFERASE (CGTASE)

open access: yesBoletim do Centro de Pesquisa de Processamento de Alimentos, 2004
Uma cultura de bactéria alcalofílica, bastonete Gram+, com alta capacidade de produção da enzima ciclodextrina glicosiltransferase (CGTase) foi isolada de amostras de solo da cidade Ouro Preto, Minas Gerais (Brasil). A produção máxima da enzima ocorreu a 37°C após 72 horas de incubação, sob agitação de 120 ciclos por minuto, em meio alcalofílico (pH 10,
