“…To overcome this challenge, we used gentler EDTA-based decalcification using Osteosoft ® reagent, or self-prepared EDTA-based solutions with pH 7.25. Previously, good results with respect to the isolation of organic matrices from corals [73,74], mollusks shells [20], sea urchin spines [75] using chelating EDTAcontaining solutions were reported. The effectiveness of this strategy was also confirmed in the present work, where it was possible to isolate conchixes of almost perfect integrity from representatives of both aquatic and terrestrial species of mollusks from different taxa (see Figs.…”

Molluscan shells are an example of a mineral-based biocomposite material, and most studies to date have focused on understanding their biomineralization mechanisms. Meanwhile, large amounts of these shells are produced as waste globally by seafood which is used by other industries as a source of biogenic calcium carbonates. In this study, we propose a simple methodological approach for isolation of Conchixes, the organic scaffolds that resemble the size and shapes of mollusks shells, using gentle EDTA-based demineralization of the shells. Such mineral-free biological materials have been extracted from selected representatives of marine and fresh water bivalves, as well as from marine and terrestrial gastropods under study. Key pathways to practical applications of molluscan conchixes with regards to pharmacy, cosmetics, feed and feed additives, biomedicine and bioinspired materials science are also discussed.

“…For example, cuttlebone, the endoskeleton of the mollusk Sepia officinalis , has an interconnected porous structure with 80% porosity and pore size between 200 and 500 μm [ 234 ]. A simple enzymatic and hydrogen peroxide-based treatment has been proposed to produce nanostructurally-organized sea dollar spines [ 235 ]. Because of their porosity, microstructure and biocompatibility, marine skeletons have great potential in bone tissue engineering.…”

Marine resources have tremendous potential for developing high-value biomaterials. The last decade has seen an increasing number of biomaterials that originate from marine organisms. This field is rapidly evolving. Marine biomaterials experience several periods of discovery and development ranging from coralline bone graft to polysaccharide-based biomaterials. The latter are represented by chitin and chitosan, marine-derived collagen, and composites of different organisms of marine origin. The diversity of marine natural products, their properties and applications are discussed thoroughly in the present review. These materials are easily available and possess excellent biocompatibility, biodegradability and potent bioactive characteristics. Important applications of marine biomaterials include medical applications, antimicrobial agents, drug delivery agents, anticoagulants, rehabilitation of diseases such as cardiovascular diseases, bone diseases and diabetes, as well as comestible, cosmetic and industrial applications.

“…The bone fragment 2 × 2 × 2 cm was demineralized using Osteosoft® (Merck). This is a gentle, mild decalcifying solution reagent (EDTA concentration 172 g/L, pH 7.2) which has the advantage of not damaging the proteins in calcium carbonate and phosphate-based skeletal structures [39][40][41][42] in spite of the time consuming process [43,44].…”

Extreme biomineralization: the case of the hypermineralized ear bone of gray whale (Eschrichtius robustus)

Selected hypermineralized bones (rostrum and tympanic bullae) have yet to be characterized for diverse species of whales (Cetacea). Hypermineralization in these structures is an example of extreme biomineralization that, however, occurs at temperatures around 36 °C. In this study we present the results of analytical investigations of the specimen of tympanic bulla isolated from gray whale (Eschrichtius robustus) for the first time. Examination of the internal surface of the bone mechanically crushed under a press revealed the presence of a lipid-containing phase, which did not disappear even after complete demineralization of the bone material. Additionally, analytical investigations including CARS, ATR-FTIR, Raman and XRD confirmed the presence of carbonated bioapatite and a collagen- lipid complex as the main components of this up to 2.34 kg/cm3 dense bone. Our experimental results open the way for further research on understanding of the principles of hypermineralization in highly specialized whale bones.
