Extraction and Precipitation of Chitosan from Cell Wall of Zygomycetes Fungi by Dilute Sulfuric Acid
TL;DR: The new method shows more than 76% of the chitosan present in AIM is found in AAIM, which might indicate the inability of acetic acid to separate chitOSan from the cell wall.

A new chitosan-thymine conjugate: synthesis, characterization and biological activity.
TL;DR: The chitosan-thymine conjugate inhibited (p<0.05) the proliferation of human liver cancer cells (HepG2) in a dose-dependent manner but had no cellular toxicity in non-cancerous mouse embryonal fibroblast cells (NIH 3T3).
Journal ArticleDOI
Synthesis and antimicrobial activity of some novel cross-linked chitosan hydrogels.
Nadia A. Mohamed,Mona M. Fahmy +1 more
TL;DR: The prepared hydrogels showed much higher antimicrobial activities than that of the parent chitosan, and were more potent in case of Gram-positive bacteria than Gram-negative bacteria.
Journal ArticleDOI
Microwave-assisted degradation of chitosan for a possible use in inhibiting crop pathogenic fungi.
TL;DR: The results indicated that oxidative degradation under microwave irradiation was a promising technique for large-scale production of low M(w) chitosan for use in crop protection.

Evidence on antimicrobial properties and mode of action of a chitosan obtained from crustacean exoskeletons on Pseudomonas syringae pv. tomato DC3000
Andrea Yamila Mansilla,Liliana Albertengo,María Susana Rodríguez,Adriana Debbaudt,Adolfo Eduardo Zuñiga,Claudia A. Casalongué +5 more
TL;DR: It is reported that the chitosan isolated from shrimp exoskeletons exerts cell damage on tomato DC3000, and the disease incidence in tomato inoculated with Pto DC3000 was significantly reduced in chitOSan pretreated seedlings, revealing a promising action of ch itosan as nontoxic biopesticide in tomato plants.
