Surfaces of buildings at the archaeological site of Palenque, Mexico, are colonized by cyanobacteria that form biofilms, which in turn cause aesthetic and structural damage. The structural characterization and species composition of biofilms from the walls of one of these buildings, El Palacio, are reported. The distribution of photosynthetic microorganisms in the biofilms, their relationship with the colonized substratum, and the three-dimensional structure of the biofilms were studied by image analysis. The differences between local seasonal microenvironments at the Palenque site, the bioreceptivity of stone and the relationship between biofilms and their substrata are described. The implications for the development and permanence of species capable of withstanding temporal heterogeneity in and on El Palacio, mainly due to alternating wet and dry seasons, are discussed. Knowledge on how different biofilms contribute to biodegradation or bioprotection of the substratum can be used to develop maintenance and conservation protocols for cultural heritage.
墨西哥帕伦克考古遗址上的建筑物表面被蓝藻定殖，形成生物膜，从而导致美观和结构损坏。报道了来自这些建筑物之一 El Palacio 的墙壁上生物膜的结构特征和物种组成。通过图像分析研究了生物膜中光合微生物的分布、它们与被定殖基底的关系以及生物膜的三维结构。描述了帕伦克遗址局部季节性微环境、石头的生物可接受性以及生物膜与其基底之间的关系之间的差异。讨论了在 El Palacio 中，由于干湿季节交替等原因，能够承受时间异质性的物种的发展和持久性的意义。了解不同生物膜如何促进基底的生物降解或生物保护，可以用于制定文化遗产的维护和保护协议。
