Biominerals are generated by the subtle interaction of biological organization and mineral growth. They belong both to the living and the inanimate world and as such their genesis is among the most intri guing and fundamental subjects in science. However, the conceptual and technical resources that are available in physical chemistry and in the biological sciences is often inadequate for the elucidation of the pro blems involved, and hence this field is particularly difficult to ex plore. This may be an important reason why fundamental research on bio mineralization mechanisms has traditionally been carried out by a com paratively small group of scientists. There are signs, however, that the situation is ripe for a change. Various meetings on biomineralization have been organized in the last few years, particularly in the medical sector. It is generally felt that further developments in the therapy of bone and tooth diseases will be largely dependent on an improved understanding of the fundamen tal underlying mechanisms of biomineralization.

The Monera and Protista Kingdoms contain species that form many different mineral types by varying processes at different cellular locations. This book identifies the underlying trends and processes common to each group. It discusses the controls, products, and functional significance of biomineralization for such simple organisms as algae, protozoans, bacteria, and lichens--information useful to botanists, zoologists, paleontologists, and research chemists.

normal and pathological mineralization in vertebrates but also with the interesting problems involved in the formation of in tracellular deposits of calcium oxalate in plants. Here cal cium carbonate and silica may also be involved in the mineral ization processes. Calcium carbonate is an important component in the formation of mollusc and avian shells. The observation that both calcite and aragonite may be formed in biogenic cal cium carbonate raises important questions as to what factors control the formation of the final mineral phase. There is little doubt that thermodynamically less stable phases may be kinetically stabilized for long periods of time by other mole cules present in vivo. In normal mineralization, calcium salts may initially be deposited both within the cells and extracel lularly. In the latter case, the role of matrix vesicles and the ways in which the matrix components might control mineral ization were especially emphasized. There is clearly a need for more structural and functional information involving cells, matrix components, and their associated crystals. The develop ment of further techniques involving mutants, chromofluors, and fixatives for preservation of tissue and the ions present in vivo was recommended. In dealing with abnormal and pathological mineralization, the Workshop concentrated on urolithiasis, gout and pseudo-gout, and the formation of dental caries. Discussions based on the influence of media of low pH on mineral surfaces highlighted some of the factors of importance in controlling crystal dis solution.

This title takes an interdisciplinary approach to the central role of solubility in pathological biomineralisation, ranging from traditional thermodynamics and kinetics to unusual concepts such as the PILP process. The scientific background and expertise of the contributors, ranges accordingly from solubility modelling and database development, renal stone and bone implant research, Mössbauer spectroscopy and structural chemistry to biochemistry and crystallisation. The chapters all have a quantitative, physico-chemical component rather than giving purely phenomenological descriptions. The contributors deal with aspects and concepts that have not previously been common in the study of pathological biomineralisation processes.

The concept of ‘biomineralization’ signifies mineralization processes that take place in close association with organic molecules or matrices. The awareness that mineral formation can be guided by organic molecules notably contributed to the understanding of the formation of the inorganic skeletons of living organisms. Modern electron microscopic and spectroscopic analyses have successfully demonstrated the participation of biological systems in several mineralization processes, and prominent examples include the formation of bio-silica in diatoms and sponges. This insight has already made the application of recombinant technology for the production of valuable inorganic polymers, such as bio-silica, possible. This polymer can be formed by silicatein under conditions that cannot be matched by chemical means. Similarly, the efforts described in this book have elucidated that certain organisms, bacteria in deep-sea polymetallic nodules and coccoliths in seamount crusts, are involved in the deposition of marine minerals. Strategies have already been developed to utilize such microorganisms for the biosynthesis and bioleaching of marine deposits. Moreover, studies reveal that bio-polymers enhance the hydroxyapatite formation of bone-forming cells and alter the expression of important regulators of bone resorption, suggesting a potential for bone regeneration and treatment / prevention of osteoporosis.
