Chitosan is one of the most abundant natural polymer worldwide, and due to its inherent
characteristics, its use in industrial processes has been extensively explored. Because it is …

This review intended to give a brief idea of the importance of proteases applications.
Processes that involve protein hydrolysis steps find wide ranging utilizations, such as …

Chitosan, the product of chitin deacetylation, is an excellent candidate for enzyme
immobilization purposes. Here we demonstrate that papain, an endolytic cysteine protease …

Infectious diseases remain a pervasive threat to global and public health, especially in many
countries and rural urban areas. The main causes of such severe diseases are the lack of …

Candida antarctica lipase B immobilization by covalent attachment on chitosan and on
chitosan–alginate complex previously activated by different strategies was studied. Hydroxyl …

Global awareness of environmental issues has resulted in the emergence of economically
and environmentally friendly bio-based materials free from the traditional side effects of …

Chitosan (CS) nanofibers with a diameter of 150–200nm were fabricated from a mixed

Abstract Fe 3 O 4 nanoparticles (NPs) were synthesized by co-precipitating Fe 2+ and Fe 3+
in an ammonia solution. Fe 3 O 4 NPs functionalized with tannic acid were prepared. After …

Resumo Chitosan, poly [β-(1-4)-linked-2-amino-2-deoxy-D-glucose], is the N-deacetylated
product of chitin which is a major component of arthropod and crustacean shells such as …
