Journal ArticleDOI
A mechanistic study of the antibacterial effect of silver ions on Escherichia coli and Staphylococcus aureus.
TL;DR: The existence of elements of silver and sulfur in the electron-dense granules and cytoplasm detected by X-ray microanalysis suggested the antibacterial mechanism of silver: DNA lost its replication ability and the protein became inactivated after Ag(+) treatment.
Journal ArticleDOI
Chitosan as Antimicrobial Agent: Applications and Mode of Action
TL;DR: The current review of 129 references describes the biological activity of several chitosan derivatives and the modes of action that have been postulated in the literature.
Journal ArticleDOI
Chemical characteristics of O-carboxymethyl chitosans related to the preparation conditions
Xiguang Chen,Hyun Jin Park +1 more
TL;DR: In this article, the water insolubility of carboxymethyl chitosans at various pHs varied with the degree of the carboxyethylation and the reaction temperature, and the ratio of water/isopropanol in the reaction solvent.
Journal ArticleDOI
Chitosan as a potential natural compound to control pre and postharvest diseases of horticultural commodities
Silvia Bautista-Baños,A. N. Hernández-Lauzardo,M. G. Velázquez-del Valle,Mónica Hernández-López,E. Ait Barka,Elsa Bosquez-Molina,Charles L. Wilson +6 more
TL;DR: As a nontoxic biodegradable material, as well as an elicitor, chitosan has the potential to become a new class of plant protectant, assisting towards the goal of sustainable agriculture.

Biological activity of chitosan: ultrastructural study
Riccardo A.A. Muzzarelli,V. Baldassarre,Fiorenzo Conti,P. Ferrara,Graziella Biagini,G. Gazzanelli,V. Vasi +6 more
TL;DR: In the present experimental investigation, tissue repair induced by chitosan, an 86.8% deacetylated poly(GlcNAc), was monitored by morphological analysis and it is suggested that chitOSan could be considered a primer on which a normal tissue architecture is organized.
