“…ATP, along with the live biomass index could be potentially an important parameter for tracking the progression of anaerobic sludge digestion. 41,49 ATP reects uctuations in bacterial metabolic activity and provides more intracellular information than the common measurements, such as total suspended solids (TSS) and volatile suspended solids (VSS). 24 Since the greatest internal storage and energy transfer of microorganisms is performed through ATP as the main block for all metabolic activities, thus, it is not a surprise to see the growing attention of researchers to the use of ATP index on the assessment of biological treatment processes.…”

“…Accurate assessment of intracellular ATP in environmental samples is confusing due to the presence of free ATP, substances affecting ATP production and degradation, and the effect of interfering compounds. 49 Therefore, ATP can be used as a quality control criterion for FCM analysis.…”

“…A review of flow cytometry (FCM) applications in water treatment, distribution, and reuse found that FCM could be useful in facilitating direct potable reuse (DPR), as it provides fast and sensitive results and can be coupled with other analytical techniques to meet various requirements of microbial water quality assessment for safe DPR (Safford & Bischel, 2019). However, improvements are needed to understand the full potential of FCM for microbial water quality assessment (Safford & Bischel, 2019). The safety of potable water reuse of permeate from a reverse osmosis (RO) membrane system could be enhanced by online monitoring of bacterial particle counts using real-time bacteriological commercial counters, which showed higher sensitivity compared to other water quality surrogates, such as electrical conductivity (Fujioka, Makabe, Mori, Snyder, & Leddy, 2019).…”

Literature published in 2019 pertinent to water reclamation and reuse has been classified into five sections: safe reuse, treatment technologies, management, assessment, and case studies. Membranes have been widely applied in integrated processes to polish secondary effluent and achieve high-quality reclaimed water. Increased efforts have also been made to facilitate feasible and safe water reuse.

“…Successful applications are reported to provide early warning indications of unexpected water contamination events through the rapid detection of a variety of microbiological threats, including pathogenic and potentially toxic microorganisms (Vital et al, 2010;Weisse and Bergkemper, 2018;Yang et al, 2010). Moreover, flow cytometric measurements are suitable to evaluate the efficiency of various industrial microbial bioprocesses (e.g., food and pharmaceutical preparations) (Díaz et al, 2010), and the performances of engineered systems for water treatment (Besmer and Hammes, 2016;Safford and Bischel, 2019). Remarkably, FCM was also useful to determine the presence of nonliving organic and inorganic substances, including nano-and micro-sized particles, suspended solids, flocs and aggregates of various origins (Aulenta et al, 2013;Casentini et al, 2016;Liu et al, 2016).…”

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.
