Zusammenfassung der Projektergebnisse
Psychrophilic calcification occurs in both unicellular pro- and eukaryotic organisms as well as in multicellular animals like bryozoans, corals, molluscs, crustaceans, echinoderms, and fish. They are able to synthetize their calcium carbonate and/or calcium phosphate-containing skeletons under frigid environmental conditions.There is a lack of knowledge about mechanisms of calcification at temperatures near the freezing point. Low temperatures lead to exponential decreases in chemical reaction rates. Consequently, the thermodynamic aspects of biomineralization in the hard tissues of psychrophilic biocalcifiers are of principal scientific interest. For the first time selected hard tissues (teeth, bones, otoliths and scales) from diverse ice fish species have been studies with respect to identification of naturally occurring calcium phosphate phases. These biological materials have been characterized by broad variety of modern bioanalytical and physico-chemical techniques in order to determine their morphology, composition, and structure. Our experiments show with strong evidence the occurrence of crystalline hydroxyapatite within the mineralized tissues of icefish species like C. gunnari and D. mawsoni. This suggests the existence of naturally occurring mechanisms for calcification and the developing of crystalline phases at temperatures near the freezing point of sea water. During the project time, we succeed in development of novel setup for the production calcium phosphate-based composites using selected organic matrices under temperature of minus 2°C. For the first time the formation of dicalciumphosphatedihydrate (DCPD) under extreme biomimetics conditions using ice fish collagen in vitro has been confirmed.
