|Building Conservation: Stone Decay|
For biodeterioration and biodegradation of stone the most important microbial groups are algae & blue-green bacteria (cyanobacteria), autotrophic and heterotrophic bacteria and filamentous fungi.
A number of bacteria, actinomycetes, algae, fungi, blue-green bacteria (cyanobacteria) and lichens can cause decay of stone in our buildings for example Slime moulds, protozoa, nematodes and rotifers, arthropods (e.g., mites), small animals (e.g., slugs) and plants.
All types of stone building materials for example: Limestone, Sandstone, Granitic, Marble, Quartzite are susceptible to micorbial attack.
Some targeted use of chemicals, biocides, pesticides and other control treatments may be needed combined with environmental monitoring. Beware of someone recommending complete biocide treatments of an entire stone façade in a building, as this is unnecessary and does not address underlying causes.
EBS environmental approach based on prevention and maintenance provides cost-effective environmentally sustainable long term solutions.
