“…The study revealed that granite bioreceptivity affected microorganisms’ adhesion to the substrate, water stress hindered biofilm formation, and temperature promoted photosynthetic efficiency. Chl fluorescence measurements were also used to investigate the effects of water-induced stress on phototrophic SABs, where 2 days of drought were found to influence the vitality and recovery of the microorganisms (Fuentes and Prieto 2021b ). Photosynthetic pigments content and color measurements revealed that high levels of atmospheric carbon dioxide favor the development of phototrophic SABs, although the effects of increased carbon dioxide levels were counteracted by increased water availability (Prieto et al 2020 ).…”

Pigment-based color is one of the most important phenotypic traits of biofilms at the mineral–air interface (subaerial biofilms, SABs), because it reflects the physiology of the microbial community. Because color is the hallmark of all SABs, we argue that pigment-based color could convey the mechanisms that drive microbial adaptation and coexistence across different terrestrial environments and link phenotypic traits to community fitness and ecological dynamics. Within this framework, we present the most relevant microbial pigments at the mineral–air interface and discuss some of the evolutionary landscapes that necessitate pigments as adaptive strategies for resource allocation and survivability. We report several pigment features that reflect SAB communities’ structure and function, as well as pigment ecology in the context of microbial life-history strategies and coexistence theory. Finally, we conclude the study of pigment-based ecology by presenting its potential application and some of the key challenges in the research.
