Microbial destruction of ceramic materials.

A review, with 9 refs., of microbial deterioration of natural stones, concrete, ceramics, glass, and sculptures. Generally, the biol. testing of the resistance of ceramic materials to biogenic attack cannot be substituted by chem. and/or phys. testing. The biotest includes the evaluation of the interactions between microorganisms and environment, esp. the substratum (ceramic material). In the case of biogenic H2SO4 or HNO3 corrosion, the biotest of the materials in a strictly controlled simulation app. resulted in differences of the material durability, which could not be detected by other testing methods. Chem. H2SO4 attack resulted in negligible differences. Thus, the use of biotest systems enables detection within many different materials.
