Date: oct-01. 2019.
Doi: 10.1016/j.ijbiomac.2019.07.092.

Abstract:
Polygalacturonase (PG) from Aspergillus niger was immobilized using glyoxyl, vinylsulfone or glutaraldehyde-activated supports. The use of supports pre-activated with glutaraldehyde presented the best results. The immobilization of PG on glutaraldehyde-supports was studied under different conditions: [read more]

Date: jul-15. 2019.
Doi: 10.1016/j.ijbiomac.2019.04.123.

Abstract:
Ficin extract has been aminated using ethylenediamine and carbodiimide to transform all exposed carboxylic groups into amino groups, retaining around 80% of activity versus benzoyl-D,L-argininep-nitroanilide hydrochloride (BANA) and 90% versus casein. This aminated enzyme was then immobilized on [read more]
