For many years it has been realised that the weathering of stone is not merely determined by physical and chemical factors but also by biological agents. When the stone in question is a historic building or monument, the damage done constitutes an irretrievable loss of our heritage and history. Laboratory studies have commenced in Paisley to study the effect of photoautotrophs on the major sedimentary rock forming minerals, with a view to expanding this work to study the overall effect of these… Expand
Chlorophyll extraction methods for the quantification of green microalgae colonizing building facades
Using chlorophyll a as a specific biomarker of aeroterrestrial microalgae, an extraction method was developed to quantify biomass and Dimethyl formamide (DMF) proved to be the best extraction solvent. Expand
Seaweed attachment to bedrock: biophysical evidence for a new geophycology paradigm.
It is concluded that seaweeds are able to cause weathering of natural rock and the term 'geophycology' is introduced to describe seaweed-bedrock interactions, including seaweeds-induced weathering. Expand
Molecular diversity of phototrophic biofilms on building stone.
A comparative study addressing the composition of algal communities on sandstone substrata based upon the analysis of rRNA gene clone libraries from environmental samples and crude cultures finds endolithic algal morphotypes (coccoid algae and diatoms) dominant in open pores between mineral particles.

Application of Different Methods of Surface Analysis for the Early Diagnosis of Art-Stone (Calcarenite) Deterioration
The deterioration process of historical buildings is progressive and irreversible, and the timing and mode of impact are different depending on the characteristics of building materials used, localExpand
Diversity of cyanobacteria on rock surfaces
This review summarizes the current state of knowledge on aerial epilithic cyanobacterial communities on both natural and anthropogenic stone surfaces around the world and suggests further thorough research on this often neglected group of organisms is desirable. Expand
Evaluation of potential of molecular and physical techniques in studying biodeterioration
Recently, researcher’s abilities to elucidate the biogeophysical and biogeochemical mechanisms of complex biodeterioration processes occurring at monumental sites has been greatly revolutionized byExpand
Algal 'greening' and the conservation of stone heritage structures.
The findings suggested that greening had little impact on the physical integrity of stone; indeed the influence of algae on moisture regimes in stone may have a broadly bioprotective action. Expand
Eukaryotic Microorganisms and Stone Biodeterioration
The overall goal of these research efforts should be the formulation of robust models of stone deterioration that integrate biotic and abiotic factors and can be used to aid prediction and management of eukaryotic growths on stone cultural heritage. Expand
Biology of a terrestrial green alga, Chlorococcum sp. (Chlorococcales, Chlorophyta), collected from the Miruksazi stupa in Korea
T.A. Klochkova, S.-H. Kang, G.Y. Cho, C.M. Pueschel, J.A. West and G.H. Kim. 2006. Biology of a terrestrial green alga, Chlorococcum sp. (Chlorococcales, Chlorophyta), collected from the MiruksaziExpand
Aeroterrestrial Microalgae Growing in Biofilms on Facades—Response to Temperature and Water Stress
The data indicate that liquid water or 100% air humidity are the prerequisite for optimum photosynthesis and growth of aeroterrestrial microalgae, however, when dried and consequently inactive, these microorganisms can recover quickly if water is suddenly available, e.g., after rain events.

Biodiversity of photosynthetic micro-organisms dwelling on stone monuments
It was demonstrated that Lyngbya B2 and Apatococcus B4, isolated from monuments inoculated on stone slabs differing in porosity and surface roughness, had a preference for calcareous lithotypes with high values of roughness and porosity. Expand
Algal growth on building sandstones: effects of chemical stone cleaning methods
Abstract Biological growths including algae, lichens, bacteria, fungi and mosses are common on building sandstones wherever suitable conditions occur. Some growths, such as lichens, may be consideredExpand
The effect of organic acids on plagioclase dissolution rates and stoichiometry
The rates of plagioclase dissolution in solutions containing organic acids are up to ten times greater than the rates determined in solutions containing inorganic acids at the same acidity. InitialExpand
Roof shingles are often colonized and discolored by blue‐green and green algae, both of which are soil algae most frequently recovered from the atmosphere. Expand
