“…Some reports inform us that MPs do not negatively affect the performance of biological rectors and communities of bacteria crucial for wastewater purification such as nitrifiers and denitrifiers [77,78]. Others indicate that specific processes, e.g., denitrification, can be affected by the presence of MPs.…”

The recovery of valuable resources from wastewater treatment plants (WWTPs) has received a great deal of attention as part of the concept of a circular economy. Anaerobic digestion for stabilizing sewage sludge in WWTPs, which produces biogas and stabilized biosolids, is a mature technology used worldwide. However, despite the necessity of achieving safe and reliable organic recycling, studies on the effect of some emerging micropollutants on this process are rare. This knowledge gap is of growing relevance because of the increasing use of some endocrine-disrupting compounds (EDCs), microplastics (MPs), and engineered nanoparticles (NPs) in industry and human life. These compounds are ubiquitous in wastewater streams and, therefore, may have serious effects on the course of the anaerobic digestion of sewage sludge, raising concerns about their effects on the environment. This article provides a comprehensive overview of the mechanisms by which selected EDCs, MPs, and NPs affect the valorization of sewage sludge, with a focus on the production of CH4, H2, and volatile fatty acids. This study takes into consideration the performance during all stages of anaerobic digestion, the shifts in microbial abundance and diversity, and the activity of key enzymes during the treatment process.

“…Modification of sample preparation for the application of the analytical method consisted in additional grinding of all sample components. The use of bioluminescent ATP-assay in processes directly related to the study of the activity of microorganisms makes it very easy and efficient to assess the metabolic state of cells and react as quickly as possible in case of such a need [42][43][44][45][46]. It does not matter in which environment these cells are located.…”

“…The results obtained with ATP-metry are valuable for the subsequent development of the functional fibrous materials, since isolation of remaining living cells of microorganisms from tissue materials with detoxifying and decontaminating protective properties for further their analyzing by traditional microbiological methods is extremely difficult, whereas ATP extraction is possible and convenient [42][43][44][45][46]. In addition, the dependence of the residual concentration of intracellular ATP in some samples on the concentration of an antimicrobial drug used for treatment of cells makes it possible to establish the minimum inhibitory concentration of the substance or the resistance of microorganisms to this substance [23,24,29].…”

Luminescent Analysis of ATP: Modern Objects and Processes for Sensing

et al. 2022

View full text Add to dashboard Cite

Bioluminescent analysis of adenosine triphosphate (ATP) concentrations is now acquiring new applications in the form of objects and processes in which it can be effectively used for sensing. A quick analysis of biological objects and systems for which the level of ATP concentrations is one of the main parameters, and a forecast of the development of various situations in such biosystems under industrial production conditions or the ecological state of the environment, confirmed by various results of analytical control of other parameters, turns out to be simple and effective. Sanitary control, quality control of purified water, microbial analysis in the food industry, maintenance of drugs and estimation of their quality, and monitoring of the metabolic state of biocatalysts used in various biotechnological processes are between the main trends of recent applications of bioluminescent ATP-assay. Additionally, the new areas of ATP sensing are developed, and the following topics are their creation of synthetic microbial consortia, their introduction as new biocatalysts to biodegradation of pesticides, suppression of methane accumulation in model urban land fields, control of dangerous development of biocorrosive processes, design of chemical-biocatalytic hybrid processes, creation of effective antimicrobial dressing and protective tissue materials, etc. These aspects are the subject of this review.

“…The microbial community analysis was investigated through the extraction of DNA from SBRs using a FastDNA® SPIN kit for soil (MP Biomedicals, OH, USA) and the samples DNA samples were sent to Fundación FISABIO sequencing service (Valencia, Spain) for V3-V4 16S rRNA gene amplification using the primers PRO341 Fand PRO805R. The subsequent amplicon sequencing on the Illumina Miseq platform was also performed by Fundación FISABIO using a 2 × 300 nucleotide paired-end reads protocol as previously described (Bretas Alvim et al, 2021;. Statistical analysis was determined by one-way analysis of variance (ANOVA).…”
