Association with a surface is an important aspect of survival for microorganisms in natural and manmade environments/Both bacteria and diatoms are involved in such associations. In many cases, this leads to surface fouling, which often results in surface deterioration and mechanical failure in industrial systems. We now know that microorganisms exploit many strategies to establish associations with surfaces. As in the case of other cellular processes, calcium ions seem to play an important role in adhesion of cells to surfaces. Calcium is involved in non-specific interactions such as neutralization of the electrical double layer between cell and substratum surface as well as specific adhesive interactions that cannot be replaced by other cations. The unique properties of calcium ions promote both specific and non-specific interactions with protein and polysaccha-ride adhesin molecules at the cell surface. As important, but less well understood, calcium ions also influence the way microbial cells interact with different substrata.
与表面的关联是微生物在自然和人为环境中生存的一个重要方面/细菌和硅藻都参与了这种关联。在许多情况下，这会导致表面污垢，这通常会导致工业系统中的表面恶化和机械故障。我们现在知道，微生物利用许多策略与表面建立关联。与其他细胞过程一样，钙离子似乎在细胞与表面的附着中起着重要作用。钙离子参与非特异性相互作用，例如中和细胞和基质表面之间的电双层，以及特异性的粘附相互作用，这些相互作用不能被其他阳离子取代。钙离子的独特性质促进了细胞表面上蛋白质和多糖黏附分子的特异性和非特异性相互作用。同样重要但了解较少的是，钙离子还会影响微生物细胞与不同基质相互作用的方式。
