<i>Tersicoccus phoenicis</i> (Actinobacteria), a spacecraft clean room isolate, exhibits dormancy.

ABSTRACT: Space missions or spacecraft equipment destined for sensitive environments, such as Mars, Europa, or Enceladus, are required to be designed to avoid forward contamination. Spacecraft are assembled in clean rooms (SACs) employing treatments to eliminate microbial contamination. However, some organisms can survive the cleaning procedures. Characterization of these populations, through both culture-based and sequencing methods, reveals that the majority consists of spore-forming bacteria. However, a smaller group of non-spore-forming organisms, primarily classified within the order Micrococcales of the phylum Actinobacteria (Actinomycetota), exists in some SACs. Despite their repeated occurrence and isolation, actinobacterial strains associated with SACs have not been stu
