Abstract
Serratia marcescens has been detected in space habitats. To explore the influence of the space flight environment on this bacterium, we investigated the genome sequence of LCT-SM166, which was isolated after space flight and has a specific carbon source utilization pattern.
Highlights
Serratia marcescens has been detected in space habitats
There is significant evidence that changes in bacterial properties are associated with the space flight environment
Strain LCT-SM166 was selected after the space flight because it has apparent differences in carbon source utilization from those of the ground control strain; this strain was subjected to whole-genome sequencing
Summary
Serratia marcescens has been detected in space habitats. To explore the influence of the space flight environment on this bacterium, we investigated the genome sequence of LCT-SM166, which was isolated after space flight and has a specific carbon source utilization pattern. There is significant evidence that changes in bacterial properties are associated with the space flight environment. These changes include alterations in proliferation rate, cell physiology, cell metabolism, biofilm formation, virulence, and drug resistance (1). Serratia marcescens appears to be a common environmental organism and has been detected in European spacecraftassociated clean rooms and in the Herschel Space Observatory (2).
