“…Proteobacteria was the most dominant bacterial phylum (ranging from 47% to 52%) in the AS samples. This was consistent with a previous report that Proteobacteria was predominant in WWTPs and played a significant and broad role in organic and nutrient removal [28]. Moreover, Nitrospirae and Chloroflexi were the key bacterial phyla for nitrite oxidation and denitrification in AS [29].…”

Controlling wastewater pollution from centralized industrial zones is important for reducing overall water pollution. Microbial community structure and diversity can adversely affect wastewater treatment plant (WWTP) performance and stability. Therefore, we studied microbial structure, diversity, and metabolic functions in WWTPs that treat industrial or municipal wastewater. Sludge microbial community diversity and richness were the lowest for the industrial WWTPs, indicating that industrial influents inhibited bacterial growth. The sludge of industrial WWTP had low Nitrospira populations, indicating that influent composition affected nitrification and denitrification. The sludge of industrial WWTPs had high metabolic functions associated with xenobiotic and amino acid metabolism. Furthermore, bacterial richness was positively correlated with conventional pollutants (e.g., carbon, nitrogen, and phosphorus), but negatively correlated with total dissolved solids. This study was expected to provide a more comprehensive understanding of activated sludge microbial communities in full-scale industrial and municipal WWTPs.

“…Kraigher et al [28] explained this by the presence of a different bacterial community, whereas Wang et al [29] indicated a change in the metabolic pathways of the substrate. Vasiliadou et al [30] analyzed the influence of pharmaceuticals on an AS system and also indicated modifications of the microbial community as the reason for the adaptation of microorganisms in the presence of these chemicals.…”

Numerous studies have analyzed the viability of the biodegradation and removal of different compounds of emerging concern in biological systems for wastewater treatment. However, the effect on the heterotrophic biomass of organic matter removal is sometimes missed. The aim of the present research was to study the effect of the addition of a mix of three pharmaceuticals (carbamazepine, ciprofloxacin, and ibuprofen) on the behavior of the biomass in two different membrane-based biological systems treating urban wastewater. The present research studied a membrane bioreactor (MBR) pilot plant operating at a similar mixed liquor suspended solids (MLSS) concentration (about 5.5 g/L). This system works as an MBR and is combined with a moving bed biofilm reactor (MBBR-MBR) to treat real urban wastewater at 6 and 10 h of hydraulic retention time (HRT) under three different shocks of pharmaceuticals with increasing concentrations. In all cases, the organic matter removal was, in average terms, higher than about 92% of biochemical oxygen demand on the fifth day (BOD5), 79% of chemical oxygen demand (COD), and 85% of total organic carbon (TOC). Nevertheless, the removal is higher in the MBBR-MBR technology under the same HRT and the MLSS is similar. Moreover, the removal increased during the shock of pharmaceutical compounds, especially in the MBR technology. From a kinetic perspective, MBBR-MBR is more suitable for low HRT (6 h) and MBR is more effective for high HRT (10 h). This could be due to the fact that biofilm systems are less sensitive to hostile environments than the MBR systems. The removal of N-NH4+ decreased considerably when the pharmaceutical compounds mix was introduced into the system until no removal was detected in cycle 1, even when biofilm was present.

“…Terrible aquatic farming to eliminate pathogens may be caused by massively using antimicrobials, like an antibiotic, to control disease and promote growth in aquaculture animals. It can cause problems like antimicrobials residues in aquatic animal tissues, modification of bacterial resistance mechanisms, and gastrointestinal microbiota imbalance in marine animals, affecting their health (Carrera et al, 2020;Kumar et al, 2019;Vasiliadou et al, 2018;Francino, 2016).…”

Aquaculture is currently experiencing massive loss due to the outbreak of pathogenic bacteria. One of the outbreak causes is the development of pathogenic bacterial resistance to the antibacterial. The problem can be solved using microorganisms that can produce new antibacterial compounds. The purpose of this research was to obtain bacteria from fishpond water that could produce antibacterial compounds. About two out of 81 isolates could produce antibacterial compounds. Those two isolates were obtained from saltwater fishponds in North Jakarta (TS2) and Harapan Island (PHY). All fishpond water was grown in marine broth or Luria broth. Extraction of antibacterial compounds was performed using four types of solvents: chloroform, dichloromethane, ethyl acetate, and methanol. Each of the solvents showed a different result. The extraction can only be successfully performed using chloroform and dichloromethane. Extraction using dichloromethane showed a larger inhibitory clear zone than chloroform. Based on 16S rRNA gene sequencing, PHY isolate was identified as Bacillus sp. and TS2 as Acinetobacter sp. In conclusion, isolate TS2 and PHY, which produced antibacterial compounds, showed potential use as aquaculture probiotics.
