Cyanobacteria-containing biofilms from a Mayan monument in Palenque, Mexico

Biofilms containing cyanobacteria on the walls of El Palacio, a Mayan monument at Palenque, Mexico, exhibit complex three-dimensional structures and seasonal resilience, contributing to both aesthetic and structural damage. These biofilms thrive under alternating wet and dry conditions, highlighting their adaptability and potential for biodegradation or bioprotection of stone substrata. The study employed image analysis to characterize biofilm distribution, species composition, and their interaction with the colonized surfaces, providing insights into the bioreceptivity of the stone. Findings suggest that understanding these microbial dynamics could inform conservation strategies for cultural heritage sites.
