[Abstract] [Goals] [Progress]


Chitin - an abundant renewable resource and non-depositable waste by-product of shrimp fisheries - can be processed into chitosan, a valuable raw material for agricultural and medical applications. However, today's chitosans are greatly variable in purity and solubility, and ill-defined in chemical composition, molecular weight, and their biological effects. We will develop and define processing technologies for the generation of chemically, physico-chemically, and biologically well defined chitosans either by chemical or enzymatic approaches, thus up-grading cheap bulk chitosan into high added value speciality chitosans. The generation of specific recombinant antibodies and chitin modifying enzymes will allow us to set up rigorous quality control schemes for standardised processing of chitin into defined chitosans with desired high quality, properties, and reproducibility, to meet industry demands and to benefit the consumer. The feasibility of the approach will be exemplified by assessing the potential of defined chitosans to be used as consumer-safe, environment-friendly, cost-effective disease protectants in EU-relevant crops.

The CARAPAX project is part of the Fifth Framework Research Program of the European Union, Key action 5
"Sustainable Agriculture, Fisheries and Forestry" of the "Quality of Life and Management of Living Resources" Program.
