“…In a WWTP aeration tank, greater than 95% of ibuprofen was removed with aerobic biodegradation being the dominant mechanism 46 . In a lab-scale cultivated consortium from sewage sludge, 100% of ibuprofen (1 mg/L) was degraded in solution in 6 h and 90% of ibuprofen (10 mg/kg) was degraded in sewage sludge in 16 days 47 . Sulfamethoxazole, carbamazepine and gabapentin can only be partially biotransformed by several model communities with the maximum percentage of 45%, 40% and 42%, respectively.…”

Microbial biotransformation of trace organic chemicals (TOrCs) is an essential process in wastewater treatment for eliminating environmental pollution. Understanding of TOrC biotransformation mechanisms, especially at their original concentrations, is important to optimize treatment performance, whereas our current knowledge is limited. Here we investigated the biotransformation of seven TOrCs by 24 model communities. The genome-centric analyses unraveled the biotransformation drivers concerning functional genes and enzymes and responsible bacteria. We obtained efficient model communities for complete removal on ibuprofen, caffeine and atenolol, and the transformation efficiencies for sulfamethoxazole, carbamazepine, trimethoprim and gabapentin were 0-45%. Biotransformation performance was not fully reflected by the presence of known biotransformation genes and enzymes. However, functional similar homologs to existing biotransformation genes and enzymes (e.g., long-chain-fatty-acid-CoA ligase encoded byfadDandfadD13gene, acyl-CoA dehydrogenase encoded byfadE12gene) could play critical roles in TOrC metabolism. Finally, we identified previously undescribed degrading strains, e.g.,Rhodococcus qingshengiifor caffeine, carbamazepine, sulfamethoxazole and ibuprofen biotransformation, and potential transformation enzymes, e.g., SDR family oxidoreductase targeting sulfamethoxazole and putative hypothetical proteins for caffeine, atenolol and gabapentin biotransformation.

“…Table 1 presents a thorough examination of different bacteria and their role in the purification of industrial effluents through bioremediation. We provide a comprehensive analysis of the physiological mechanisms employed by bacteria, the specific genes involved in these mechanisms, the types of contaminants they can target, the industries where these pollutants are frequently encountered, and the varying degrees of degradation efficiency exhibited by different bacterial species (Aguilar-Romero et al, 2024;Ezeorba et al, 2024;Huang et al, 2024;Ray and Pattnaik, 2024;Sajjad et al, 2024;Yang et al, 2024).…”

In this study, we delved into cutting-edge strategies for the effective management of wastewater, a critical issue exacerbated by industrial pollution and urban expansion. We introduce the use of carbon-based nanomaterials (CBNs), either alone or functionalized with bacteria, as a novel nanobiotechnological solution for urgent nanobioremediation needs. This technique is notable for its exceptional ability to remove various industrial pollutants, including heavy metals, pesticides, textiles, and dyes, emphasizing the pivotal role of CBNs. The development of bionanocomposites through the integration of CBNs with bacteria represents a significant advancement in enhancing bioremediation efforts. In this study, we assessed the potential health and environmental risks associated with CBN usage while offering an in-depth evaluation of the adsorption mechanisms and factors influencing bioremediation effectiveness. Furthermore, the improved efficiency in treating industrial effluents facilitated by bionanocomposites was investigated, and their alignment with circular economy principles through recyclability is discussed. We aimed to provide, a detailed overview of recent advancements, challenges, and prospects for CBNs and bacterial application in sophisticated wastewater treatment, underscoring their vital importance in promoting the environment.
