Bacterial Response to Microgravity

Long-term Microbial growth under simulated microgravityTowards understanding the long-term response of microbial communities to the microgravity environment of space, Escherichia coli cells were grown under low-shear modeled microgravity (LSMMG) conditions for over 1000 generations (1000G) in steam-sterilized High Aspect Ratio Vessels (HARVs) and in HARVs in which the sterilization was accomplished using chloramphenicol treatment between cycles. The genome of the steam-sterilized HARV grown strain (1000G) was compared with that of the strain grown in chloramphenicol treated HARV (1000G-BA).
