Abstract. Buildings at the important archaeological sites of Uxmal and Kabah, Mexico, are being degraded by microbial biofilms. Phospholipid fatty acid (PLFA) and chlorophyll a analyses indicated that phototrophs were the major epilithic microorganisms and were more prevalent on interior walls than exterior walls. Culture and microscopical techniques showed that Xenococcus formed the major biomass on interior surfaces, but the stone-degrading genera Gloeocapsa and Synechocystis were also… 
Algae and cyanobacterial diversity and distribution patterns on mayan buildings in Palenque, Chiapas
TLDR
It is demonstrated that coccoid cyanobacteria are the main colonizers on Latin American monuments under tropical and subtropical conditions and the assessment of their potential deteriogenic activity requires the further development of rapid molecular techniques.
Algal and Cyanobacterial Biofilms on Calcareous Historic Buildings
TLDR
Comparison of the phototrophs on cement-based renderings and limestone substrates at 14 historic locations in Europe and Latin America confirms the influence of both climate and substrate on phototrophic colonization of historic buildings.
Cyanobacterial diversity and ecology on historic monuments in Latin America.
TLDR
Results here show demonstrate that coccoid cyanobacteria are the main colonizers on Latin American monuments under tropical and subtropical conditions and the assessment of their potential deteriogenic activity requires the further development of rapid molecular techniques.
Microbial Biofilms on the Sandstone Monuments of the Angkor Wat Complex, Cambodia
TLDR
Results show that these microbial biofilms from Cambodian temples Angkor Wat, Preah Khan, and the Bayon and West Prasat contained a microbial community dominated by coccoid cyanobacteria that are resistant to dehydration and high levels of irradiation and can be involved in deterioration of sandstone.
Extracellular polymers of microbial communities colonizing ancient limestone monuments.
TLDR
This chapter describes procedures to extract and characterize the polysaccharidic fraction of naturally occurring microbial exopolymers associated with epilithic biofilms.
Microbial deterioration of stone monuments--an updated overview.
TLDR
A critical review of work on microbial biofilms on buildings of historic interest, including recent innovations resulting from molecular biology, is presented and microbial activities causing degradation are discussed.
Analysis of Salt-Containing Biofilms on Limestone Buildings of the Mayan Culture at Edzna, Mexico
TLDR
Biofilms on the salted ceiling of a limestone tunnel at the Mayan site of Edzna, Mexico, were characterised using SEM, EDS, chemical analysis, light microscopy, culture and pigment analysis, finding salt crystals, mainly sulfates, were found throughout the stone.
Cyanobacterial Biofilms in Monuments and Caves
Biofilm-forming cyanobacteria are widespread inhabitants of exposed stones in archaeological and historical sites and caves. Outdoors, these phototrophic biofilms are adapted to all types of stress
Life on the rocks.
TLDR
Subaerial biofilm metabolic activity centres on retention of water, protecting the cells from fluctuating environmental conditions and solar radiation as well as prolonging their vegetative life, which manifests itself as bio-weathering of rock surfaces.
Microbial ecology of phototrophic biofilms
TLDR
The results suggest that surface colonization by heterotrophic pioneers facilitates the development of phototrophic biofilms and demonstrate that nifD gene sequences, coding for a nitrogenase subunit, can be used to detect and identify diazotrophic cyanobacteria in natural communities.

TLDR
In both field and laboratory samples, the microbial film showed on its reverse side the presence of grains removed from the stone surface, thus causing mechanical deterioration on the colonized materials.

Bacterial abundance and diversity in the Barbados Trench determined by phospholipid analysis
TLDR
The Barbados trench is characterized by large fields of volcanoes and mounds located over a distance of 30 km above the northern slope of a basement ridge corresponding to an inactive transform fault and revealed the presence of sulfur-oxidizing bacteria common to many deep-sea sites but also a large contribution of type I and type II methanotrophs to the eubacterial biomass.
