AbstractSoils and sediments are heterogeneous natural ecosystems holding great microbial diversity. These environments are very different of laboratory conditions where microorganisms are usually isolated and cultured. For instance, soil upper layers experience drastic changes ruled by climate and soil microorganisms can be exposed to a broad range of temperatures1 (Figure 1). In spite of current advancements on environmental microbiology, the functioning of microorganisms in nature remains scarcely known. Microorganisms present distinctive survival strategies to face adverse conditions, for example, the formation of spores or dormancy states which involve physiological transformations2. At present, the presence of thermophilic microorganisms (e.g., genus Parageobacillus) at a vegetative state in soils and sediments is known3,4, suggesting that they can remain active over a wide range of environmental conditions although this strategy remains to be well understood.
