“…Thus, for P. aeruginosa, a slight decrease of the optical density values is observed (Figure 8) by adding antibiotics at low concentrations (0.1-0.2 µg/mL), followed by an increase in OD at higher OTC concentrations. This increase could also be attributed to the bacterial species' exposure to the antibiotic in the environment and the antimicrobial effect of OTC being more pronounced at lower concentrations [20,22]. The behavior of C. violaceum (Figure 9) is different to that of P. aeruginosa, a tendency for the continuous increase of OD values with increasing OTC concentration, for all types of biofilters used, having been observed.…”

“…Vanysacker et al [49] obtained similar results when studying the development of P. aeruginosa on membranes with different chemical characteristics, highlighting a nonrepetitive effect of the membrane on the adhesion capacity of the biofilm. At the same time, the increase in the amount of biofilm with the increase in antibiotic concentration suggests an adaptation of bacterial species to OTC by developing mechanisms to prevent the antimicrobial effect of the antibiotic [20,50]. Therefore, the use of P. aeruginosa and C. violaceum strains may have a high potential for biotreatment of aquaculture wastewater, even in waters contaminated with antibiotics.…”

“…Antibiotics are a class of medicinal substances very commonly used both in human and veterinary medicine, as well as in agriculture and aquaculture [19], but which make a significant contribution to water contamination and environmental pollution, with longterm adverse effects on aquatic ecosystems [20]. Even in the case of advanced technologies, conventional biological wastewater treatment systems achieve low treatment rates of antibiotics in their effluents.…”

The presence of nutrients in aquaculture water bodies causes serious problems for aquatic ecosystems, requiring the development of technical solutions to reduce their amounts. This work identifies some bacterial strains that are able to reduce nutrient quantities and studies the effect of antibiotics on bacterial growth, on the ability to form biofilms on different solid supports, and on the ability to reduce nutrients in aquaculture wastewater. Bacterial biofilm adhesion on different substrates depends on the surface properties of the substrate, on the bacterial types that form the biofilm, but also on biofilm–substrate interactions. The obtained results revealed the high capacity of biofilm-forming bacterial strains of Pseudomonas aeruginosa and Chromobacterium violaceum to eliminate up to 87% of nitrate and nitrite ions and up to 62% of phosphate ions in the presence of concentrations of 0.1–0.4 µg/mL of oxytetracycline antibiotic from aquaculture wastewater.

“…As shown in Table 1 , physical methods such as adsorption, sedimentation, flocculation, and filtration only separate the antibiotic residues from the water and generate problematic products such as brine and contaminated adsorbents. Alternatively, biological approaches have recently emerged, and most antibiotic residues in the environment can be removed through this route [36] , [37] , [38] . However, the artificial introduction of active organisms into aquatic environments may disrupt the ecological balance of their biomes, which may cause irreversible ecosystem damage.…”

“…The biological oxygen demand (BOD) refers to the amount of oxygen consumed in the biodegradation of a particular compound. The samples examined in this study were inhibitory industrial wastewaters [3,4]. This means that the BOD of the raw water was low or zero, since the bacteria could not decompose the sample when they could not function in the solution.…”

Reliability of Biodegradation Measurements for Inhibitive Industrial Wastewaters

et al. 2022

Industrial wastewaters may contain toxic or highly inhibitive compounds, which makes the measurement of biological oxygen demand (BOD) challenging. Due to the high concentration of organic compounds within them, industrial wastewater samples must be diluted to perform BOD measurements. This study focused on determining the reliability of wastewater BOD measurement using two different types of industrial wastewater, namely pharmaceutical wastewater containing a total organic carbon (TOC) value of 34,000 mg(C)/L and industrial paper manufacturing wastewater containing a corresponding TOC value of 30 mg(C)/L. Both manometric respirometry and the closed-bottle method were used in the study, and the results were compared. It was found that the dilution wastewaters containing inhibitive compounds affected BOD values, which increased due to the decreased inhibiting effect of wastewater pollutants. Therefore, the correct BOD for effluents should be measured from undiluted samples, while the diluted value is appropriate for determining the maximum value for biodegradable organic material in the effluent. The accuracy of the results from the blank samples was also examined, and it was found that the readings of these were different to those from the samples. Therefore, the blank value that must be subtracted may differ depending on the sample.
