Antimicrobial and antioxidant linen via laccase-assisted grafting
Silva, Carla Manuela; Matamá, Maria Teresa; Padrão, Jorge; Kim, Suyeon; Prasetyo, E. N.; Kudanga, T.; Nyanhongo, Gibson S.; Guebitz, G. M.A laccase from Ascomycetemyceliophthora thermophila was used to assist the binding of chitosan and catechin onto a previous enzymatically oxidized linen surface. The process consists of the pre-treatment of the linen with laccase followed by the application of chitosan in a first step and catechin plus laccase in a second step. The results presented here support the conclusion that laccase is able to oxidize ph...
Polymerization of lignosulfonates by the laccase-HBT (1-hydroxybenzotriazole) s...
Prasetyo, E. N.; Kudanga, T.; Østergaard, L.; Rencoret, J.; Gutiérrez, A.; Río, J. C. del; Santos, J. I.; Nieto, L.; Jiménez-Barbero, JesúsThe ability of laccases from Trametes villosa (TvL), Myceliophthora thermophila (MtL), Trametes hirsuta (ThL) and Bacillus subtilis (BsL) to improve the dispersion properties of calcium lignosulfonates 398 in the presence of HBT as a mediator was investigated. Size exclusion chromatography showed an extensive increase in molecular weight of the samples incubated with TvL and ThL by 107% and 572% from 28400 Da a...
