Chitosan
Oligosaccharide refined from Chitosan, which made from the Alaska deep sea snow
crab shells, using high tech means and modern biological fermentation
technology. It has low molecular weight, good water solubility and biological
activity. Chitosan oligosaccharide can be easily absorbed by plants, animals
and human beings. It also has the following properties: pure natural, no
radiation, no pollution, no additives features
What are the side effects of using chitosan?
Chitosan is often used in plant disease control as a powerful elicitor rather than a direct antimicrobial or toxic agent. Its direct toxicity remains dependent on properties such as the concentration applied, the molecular weight, degree of acetylation, solvent, pH and viscosity. best chitosan supplement are naturally occurring compounds that have potential in agriculture with regard to controlling plant diseases. These molecules were shown to display toxicity and inhibit fungal growth and development. They were reported to be active against viruses, bacteria and other pests. Fragments from chitin and chitosan are known to have eliciting activities leading to a variety and type of that and of defense responses in host plants in response to microbial infections, including the accumulation of phytoalexins, pathogen related proteins and proteinase inhibitors, lignin synthesis, and callose formation.Chitosans are well used in the fresh and salt water purification process as chelators for minerals and metals. These abilities are also explored when chitosan is applied to plants to prevent diseases because it can chelate nutrients and minerals, preventing pathogens from accessing them. These polysaccharide molecules were also reported to bind mycotoxins, which may reduce damage to the host tissues due to toxins.
Biological Effects and Applications of Chitosan
chitosan for plants pathogens has been extensively explored with more or less
success depending on the pathosystem, the used derivatives, concentration,
degree of deacylation, viscosity, and the applied formulation soil amendment,
foliar application; chitosan alone or in association with other treatments. For
example, Muzzarelli et al. tested the effectiveness of five chemically modified
chitosan derivatives in restricting the growth of Saprolegnia parasitica.
Results indicated that methylpyrrolidinone chitosan nanoparticles, phosphonomethyl chitosan,
and carboxymethyl chitosan, as opposed to dicarboxymethyl , did not allow
the fungus to grow normally.
Best place to buy chitosan with affordable price
Chitosan is a naturally occurring linear polysaccharide that comes from the deacetylation of chitin. This novel biomaterial yields after further hydrolysis an extremely low molecular weight oligosaccharide. Chitosan has many useful properties; it is nontoxic, antibacterial, and environmentally friendly with no acidic degradation products. Its major uses are in the development of edible films, polyurethane paint, and biopesticides, although common applications range from water treatment to chromatography, cosmetics, textile treatment, textiles, photographic papers, biomedical devices, tissue engineering and regeneration wound healing, hemodialysis membranes, and implant coatings for controlled release in gene or drug delivery.

chitosan price is based on varieties. Chitin is a natural polymer extracted mostly from shrimp or crab shells and is the Earth’s second most abundant polysaccharide. After a simple acetylation procedure, chitin is converted into chitosan that consists in a polysaccharide structure of deacetylated-β-glucosamine. Chitosan has been largely employed in wastewater treatment the removal of colloids through coagulation-flocculation processes. Different chitosan based materials have been produced and tested in the removal of inorganic pollutants such as toxic metals and metalloids, nutrients, dyes, micropollutants and hydrocarbons. Sorbents such as magnetic-activated carbon chitosan have been successfully tested in the removal of antibiotics (ciprofloxacin, erythromycin and amoxicillin) from water. Raw chitosan and ZnO nanoparticles entrapped in chitosan have demonstrated an excellent potential for the removal of the insecticide permethrin from aqueous effluents. Chitin and chitosan in flake and powder form have also demonstrated a promising effectiveness in the removal of oil spilled in seawater. Superhydrophobic and superoleophilic sponges modified by thioles have been also prepared from chitosan and used for the removal of oil spills. Chitosan hydrogels have been tested as well as entrapment matrices for the immobilization of hydrocarbon-degrading biomass for oil spills. Strains such as R. corynebacterium, Bacillus subtilis. pumilus have been successfully immobilized and employed in hydrocarbon degradation processes. In this book chapter, the use of chitosan and chitosan-based materials in the removal of organic pollutants from water is reviewed.
