New insights into the structure and composition of cement from the common Eastern oyster
Abstract
Many marine creatures are known to generate biological adhesives for a variety of purposes. Isolating and studying these biomaterials can lead to the development of new synthetic materials as well as point toward novel antifouling strategies. Blue mussels (Mytilus edulis) can deposit a protein-rich adhesive plaque that displays impressive tensile strength. A method to quickly and accurately measure the adhesive strength of these small and irregularly shaped plaques is necessary to be able to make comparisons to traditional synthetic glues. The work presented here aims to provide a quick and accurate method for determining the adhesion strength of plaques from the common blue mussel. Larval Eastern oysters (Crassostrea virginica) also produce an adhesive for initial surface attachment during their settlement stage. Studies have been done on the composition of this material yet little is known as to the exact mechanism through which it is applied or its microstructure. Adult specimens of oysters have been shown to generate a different form of adhesive that contains a large inorganic (CaCO3) component. Little compositional data exists on this cement generated by the Eastern oyster ( C. virginica). Some of the first compositional and microstructural insights on the adhesives generated by adult and larval stage specimens of Eastern oysters are presented in this work.
