“…Significant removal of microbial ATP (60 %) was found in DMF1 in combination with inline coagulation (0.3 -1.5 mg-Fe 3+ /L). This is close to the reported removal (65 -85 %) in a pilot seawater media filter (without coagulation) fed with seawater from the North Sea (Abushaban et al 2019b). Further removal of microbial ATP was seen in the DMF2 (45 %) and the CF (16 %).…”

“…In total, more than 86 % of microbial ATP was removed through the SWRO pre-treatment. Abushaban et al (2019b) reported higher removal of microbial ATP (95 %) in a full-scale SWRO plant with two stages of DMFs (with similar properties of the DMFs of the monitored plant) coupled with inline coagulation (1.3 mg-Fe 3+ /L). The higher removal of microbial ATP is attributed to the higher coagulant dosage prior to DMF in this study.…”

“…These results were in line with ATP data measured directly on-board within the experiment T2 carried out during Euromir-95 mission (Guarnieri et al, 1997). Recently, the ATP-metry was selected for Today, commercial kits for quantitative ATP-metry are available to monitor the microbial biomass level in water and to validate cleaning and disinfection procedures, with a wide number of bulk and intracellular ATP measurements on microbial communities reported from natural and engineered aquatic environments (Abushaban et al, 2019;Fillinger et al, 2019; van der Wielen and van der Kooij, 2010;Vang et al, 2014). However, most applications in water monitoring on Earth have not been used as frequently as expected.…”

Space exploration is demanding longer lasting human missions and water resupply from Earth will become increasingly unrealistic. In a near future, the spacecraft water monitoring systems will require technological advances to promptly identify and counteract contingent events of waterborne microbial contamination, posing health risks to astronauts with lowered immune responsiveness. The search for bio-analytical approaches, alternative to those applied on Earth by cultivation-dependent methods, is pushed by the compelling need to limit waste disposal and avoid microbial regrowth from analytical carryovers. Prospective technologies will be selected only if first validated in a flight-like environment, by following basic principles, advantages, and limitations beyond their current applications on Earth. Starting from the water monitoring activities applied on the International Space Station, we provide a critical overview of the nucleic acid amplification-based approaches (i.e., loop-mediated isothermal amplification, quantitative PCR, and high-throughput sequencing) and early-warning methods for total microbial load assessments (i.e., ATP-metry, flow cytometry), already used at a high readiness level aboard crewed space vehicles. Our findings suggest that the forthcoming space applications of mature technologies will be necessarily bounded by a compromise between analytical performances (e.g., speed to results, identification depth, reproducibility, multiparametricity) and detrimental technical requirements (e.g., reagent usage, waste production, operator skills, crew time). As space exploration progresses toward extended missions to Moon and Mars, miniaturized systems that also minimize crew involvement in their end-to-end operation are likely applicable on the long-term and suitable for the in-flight water and microbiological research.
