Evaluation of molar weight and deacetylation degree of chitosan during chitin deacetylation reaction: Used to produce biofilm
Catarina Motta de Moura,Jaqueline Motta de Moura,Niege Madeira Soares,Luiz Antonio de Almeida Pinto +3 more
TL;DR: In this article, the authors studied the chitin deacetylation reaction, by the viscosity average molar weight of chitosan as a function of reaction time.
Journal ArticleDOI
Active packaging with antifungal activities
TL;DR: The effects of essential oils, preservatives, natural products, chemical fungicides, nanoparticles coated to different films, and chitosan in vitro on the growth of moulds, but also in vivo on the mould free shelf-life of bread, cheese, and fresh fruits and vegetables are examined.

Inhibition of microbial pathogens by fungal chitosan
Ahmed A. Tayel,Shaaban H. Moussa,Klaus Opwis,Dierk Knittel,Eckhard Schollmeyer,Anna Nickisch-Hartfiel +5 more
TL;DR: Gram positive bacteria were generally more sensitive to chitosan antimicrobial action than Gram negative strains and this action was notably affected by the environmental growth conditions, i.e. incubation temperature and pH value.

Probing the Modes of Antibacterial Activity of Chitosan. Effects of pH and Molecular Weight on Chitosan Interactions with Membrane Lipids in Langmuir Films
TL;DR: It was found that while chitosan had a negligible effect on DPPC monolayers over the pH range studied, it distinctly affected DPPG and cholesterol monolayer, and the effect onDPPG was found to decrease with increasing pH.
