Genome Sequences of Three Common Bacterial Isolates from Wastewater from the Water Processor Assembly at the International Space Station

Abstract

Bacteria from the genera Burkholderia , Ralstonia , and Methylobacterium were consistently detected in water of the life support systems at the International Space Station. Here, we report complete genomes of recent isolates that are representative of these genera to support future studies in biofilm and wastewater treatment in space habitats.

Genome Sequences of Bacteria Isolated from the International Space Station Water Systems

“…Water-associated bacteria capable of biofilm formation onboard the International Space Station (ISS) have represented a challenge for the operation of the environmental control and life support system (ECLSS) ( 1 ). Bacteria isolated from the water recovery system, which recycles urine, humidity condensate, and other nonpotable water to water for crew consumption and hygiene, have been used in multiple ground studies that pertain to ECLSS biofouling ( 2 – 5 ). Similarly, isolates from the Russian SRV-K, which recovers water from humidity condensate, and the SVO-ZV, which supplies ground water delivered to the ISS, have been and continue to be investigated ( 6 ).…”
