Biological activities of chitosan and chitooligosaccharides (2011, methodology): “However, Zheng and Zhu (2003) used E. coli and S. aureus to study the antimicrobial activity of chitosans with different molecular weights (Mw).”
Preparation and antibacterial activity of chitosan-based nanocomposites containing bentonite-supported silver and zinc oxide nanoparticles for water disinfection (2015, background): “…for transition-metal ions and organic species because the amino (\\NH2) and hydroxyl (\\OH) groups on Cts chains can serve as coordination and reaction sites (Zheng and Zhu, 2003; Chang and Juang, 2004; Li et al., 2008; Raafat and Sahl, 2009; Kittinaovarat et al., 2010; Guibal et al., 2013).”
Modification of Chitosan for the Generation of Functional Derivatives (2019, background): “cerevisiae cells treated with sublethal doses of CS strengthen their wall and become resistant to beta-glucanase treatment [122,124]; (vi) Disruption of the membrane and release of cellular components are often reported, especially for Gram negative bacteria and for some yeasts [111], but depending ”
A Biopolymer Chitosan and Its Derivatives as Promising Antimicrobial Agents against Plant Pathogens and Their Applications in Crop Protection (2011, background): “coli in some studies [351, 352], while in the others an increased activity for a high MW (HMW) in comparison with LMW chitosan have been found [353].”
