The study monitored the effect of tetracycline on bacterial biofilm formation and compared biofilm formation by resistant bacterial strains in different phases of the wastewater treatment process in wastewater treatment plant (WWTP). The crystal violet staining method was used to evaluate the biofilm formation. Biofilm-related bacterial properties were characterized by hydrophobicity, autoaggregation and motility tests. The relative abundance of tetracycline resistance genes (tetW, tetM, tetO, tetA and tetB) in wastewaters were subsequently quantified using qPCR. The results show that the isolates from the nitrification tank produce biofilm with up to 10 times greater intensity relative to the isolates from the sedimentation tank. In isolates of Aeromonas sp. from the nitrification tank, increased biofilm production in the occurrence of tetracycline from a concentration of 0.03125 µg/mL was observed. The tetW gene showed the highest relative abundance out of all the tested genes. From the sampling points, its abundance was the highest in the sedimentation tank of the WWTP. Based on these results, it can be assumed that resistant bacteria are able to form a biofilm and sub-inhibitory tetracycline concentrations induce biofilm formation. WWTPs thus represent a reservoir of antibiotic resistance genes and contribute to the spread of resistance in the natural environment.

“…Regarding the airborne bacteria concentration at sewage plants, a strong-quality study conducted by Cyprowoski et al ( 32 ) tried to assess the exposure to anaerobic bacteria released into the air at the WWTP in Poland. They collected 12 samples for 6 sampling points via stationary air samplers in a year.…”

Background: Sewage workers have a higher risk of exposure to various potential occupational respiratory hazards found in sewage plants. Although previous studies discuss occupational respiratory hazard concentration impacting sewage workers' respiratory health, the results are scarce and mixed. Hence, there is a need to identify the potential respiratory hazards in sewage plants so as to clarify the short- and long-term respiratory health effects. Therefore, this systematic review (SR) aims to critically review previous studies investigating potential respiratory hazards found at sewage plants and their effects on sewage workers' respiratory health.Methods: An SR was conducted using PubMed, EBSCO Medline, Web of Science, Scopus, and Google Scholar on peer-reviewed studies published between January 1994 and October 2020 evaluating the impact of potential exposure to respiratory hazards and its effects on respiratory health among sewage workers. “Sewage treatment plant,” “respiratory hazards,” and “respiratory health effects” were the three main search terms chosen in this SR. The inclusion criteria were (1) studies on potential occupational respiratory hazard exposure among sewage workers, (2) manuscripts written in English, and (3) studies published in the peer-reviewed literature. The human observational studies' quality was assessed using the Effective Public Health Practice Project Quality Assessment Tool.Results: We identified 5,660 articles through an initial database search. Only 26 items met the inclusion criteria and were included in this review; 15 human observational studies and 11 environmental assessment studies were conducted in the sewage industries. Most of the human observational studies were rated as moderate quality, two studies were rated as weak quality, and one study with strong quality was identified. Hydrogen sulfide, bioaerosols, particulate matter 2.5 (PM 2.5), and volatile organic compounds (VOC) were found to be potential respiratory hazards. Most of the risks contributed to adverse outcomes on the sewage workers' respiratory health with some inconsistent findings on the relationship between respiratory hazard exposure and respiratory health effects.Conclusion: Our review finds that, although this area is of great importance, quality studies are still lacking. There is a need for additional studies to clarify the effects of respiratory hazard exposure on sewage workers and respiratory health, especially PM 2.5 and VOC.

“…In the samples of wastewater that is used as a means for the identification of anaerobic bacteria, the necessary conditions for the growth of these bacteria are observed, this condition is evaluated by means of the laboratory techniques used. In similar studies such as Cyprowski et al [24], it is analyzed that in the processes of wastewater treatment that have the anaerobic component, the presence of these bacteria will exist, for this research the objective is to validate those studies in wastewater present in Andean areas and use that type of bacteria to improve the degradation process of organic matter. The method of degradation of organic matter in anaerobic environments has certain limitations due to the performance of microorganisms to degrade organic matter under these conditions, but the advantage is that it has the potential to obtain methane [25], with this premise when validating the presence of methane-producing bacteria the process is viable with possible subsequent uses.…”

The degradation of organic matter in wastewater from livestock stables is analyzed with the use of anaerobic microorganisms obtained from wastewater samples from the study area. The research is divided into three phases. In the first, wastewater samples are taken from three farms in the area; in the second phase the samples are taken to the laboratory and three replicates of each collected sample are prepared to be analyzed and identified and the methanogenic bacteria that are responsible for degrading organic matter in anaerobic processes are isolated. In the last phase, two experiments are carried out with three repetitions each; in the first one, the contaminated water is placed without a previous dilution process. In the second experiment, a 75% dilution is carried out to recreate the real conditions in the treatment plants where the microorganisms are going to be applied, which suffer dilutions due to the presence of constant precipitations in the analysis area. The results show a high elimination of organic matter and fecal coliforms in the wastewater treated with the identified microorganisms , producing degradation kinetics of order 1 (exponential) with particular constants for each process.
