Biominerals and Fossils through Time
Fossils are essential to the reconstruction of the evolution of life and episodes in Earth history. Fossil skeletal material serves as the repository of chemical data widely used in the reconstruction of the Earth’s climate–ocean system at various time scales. Knowledge of biomineralization – the processes associated with the formation of mineralized biological structures – is essential to prop...
متن کاملOn the Characteristics and Growth of Biominerals
Minerals formed by organisms may either be simply a side-product of the metabolism or they carry a function, for which their properties and morphologies are controlled by the organism. The rst case, bioinduced mineralisation, was encountered in this work in the case of the precipitation of the mineral schwertmannite (Fe8O8(OH)6SO4) by the bacterial strain Leptospirillum ferrooxidans. In the lit...
متن کاملThe Organic-Mineral Interface in Biominerals
Numerous living organisms form minerals. These biogenic minerals, or biominerals, are composite materials containing an organic matrix and nanoor micro-scale amorphous or crystalline minerals. In this chapter we will review the molecular aspects of biomineralization and describe as completely as is currently possible the organic-mineral interface, the location in which organic-mineral interacti...
متن کاملModeling biominerals formed by apatites and DNA.
Different aspects of biominerals formed by apatite and DNA have been investigated using computer modeling tools. Firstly, the structure and stability of biominerals in which DNA molecules are embedded into hydroxyapatite and fluoroapatite nanopores have been examined by combining different molecular mechanics methods. After this, the early processes in the nucleation of hydroxyapatite at a DNA ...
متن کاملIR – spectroscopic characterization of biominerals in marattiaceaeus ferns
(iR – spectroscopic characterization of biominerals in marattiaceaeus ferns). Frond samples of the eusporangiate ferns Marattiaceae genera Angiopteris, Christensenia, Danaea and Marattia were investigated by infrared spectroscopy, under different experimental conditions. The results confirmed the previously reported accumulation of biogenic silica (SiO2) in tissues of these ferns and also showe...
