Cyclodextrin glycosyltransferase (CGTase) from Thermoanaerobacter sp. was covalently immobilized on glutaraldehyde-activated chitosan spheres and used in a packed bed reactor to investigate the continuous production of β-cyclodextrin (β-CD). The optimum temperatures were 75°C and 85°C at pH 6.0, respectively for free and immobilized CGTase, and the optimum pH (5.0) was the same for both at 60°C. In...
Asymmetric membranes may be used in a broad range of applications such as reverse osmosis, hemodialysis and separation of organic mixtures. In this paper, asymmetric membranes were produced using cellulose acetate (CA) from biomass: newspaper and mango seed. The degree of substitution of CA was 2.65±0.07. Different formulations were used to prepare the CA membranes: CA/dichloromethane/water with and...
