Even though extensive cleaning procedures in clean rooms and spacecraft are utilized, molecular genetics analyses show that the clean rooms harbor a diverse collection of microorganisms or a spacecraft microbiome. The Acinetobacter, a genus of bacteria, are among the dominant members of the spacecraft microbiome. In this research, the investigators showed that under ultraminimal conditions several spacecraft-associated Acinetobacter metabolize or biodegrade the spacecraft cleaning reagents of ethanol (ethyl alcohol), 2-propanol (isopropyl alcohol), and Kleenol 30 (floor detergent). The work showed that cultures grew on ethyl alcohol as a sole carbon source while displaying reasonable tolerances towards oxidative stress. This study provides a plausible biochemical explanation to the observed microbial ecology dynamics of spacecraft-associated environments. @ https://www.liebertpub.com/doi/10.1089/ast.2017.1814 More information: Rakesh Mogul et al.
