“…Many factors such as molecular weight [187][188][189] , type of solvent 190,191 , different drying condition 192 , and humidity 193 contribute to the formation of CH films.…”

“…For example, by spraying or inoculating leaves with CH, various plant species were protected against viruses such as, tobacco necrosis virus (TNV), peanut stunt virus (PSV), cucumber mosaic virus (CMC), potato virus X (PVX), and alfalfa mosaic virus (ALMV) 210,214,215 . The effectiveness of CH to inhibit viral infection depends on the concentration, deacetylation degree, and molecular weight of CH besides charge value and the character of the chemical modifications of the molecule 187,211,213 . In mammals, CH can stimulate the inductive phase of the immune response to virus antigens and nerves of the immune system.…”

“…Chitosan has been shown to control viral diseases in plants [41]. However, it is yet to be shown that viruses are directly inactivated by chitosan, which in itself would appear to be unlikely as viruses are not composed of chitin or related polysaccharides.…”

Abstract:In recent decades, a greater knowledge of chitin chemistry, and the increased availability of chitin-containing waste materials from the seafood industry, have led to the testing and development of chitin-containing products for a wide variety of applications in the agriculture industry. A number of modes of action have been proposed for how chitin and its derivatives can improve crop yield. In addition to direct effects on plant nutrition and plant growth stimulation, chitin-derived products have also been shown to be toxic to plant pests and pathogens, induce plant defenses and stimulate the growth and activity of beneficial microbes. A repeating theme of the published studies is that chitin-based treatments augment and amplify the action of beneficial chitinolytic microbes. This article reviews the evidence for claims that chitin-based products can improve crop yields and the current understanding of the modes of action with a focus on plant-microbe interactions.

“…It has been reported that chitooligosaccharides from the tetramer to heptamer display strong attracting responses to peritoneal exudate cells in BALB/c mice, and chitohexaose has significant growth-inhibitory effects against sarcoma-180, MM-46, and Meth-A solid tumours in mice [7][8][9]. Furthermore, chitohexaose has been found to enhance protective effects against infection with some microorganisms in mice [10][11][12][13].…”
