“…Even though BPA has been detected at concentrations ranging from nanograms per liter (ng L − 1 ) to micrograms per liter (mg L − 1 ) in drinking water, the long-term continuous exposure of a living organism to this EDC cannot be ignored considering its harmful impact (Sarma and Lee 2018 ). Therefore, it was interesting to estimate the toxicity of medium containing BPA (100 mg L − 1 ) and this medium inoculated with strains K1MN and BG12 after a 30-day cultivation period.…”

Bisphenol A (BPA) is an endocrine disrupting chemical. Its extensive use has led to the wide occurrence of BPA in various environmental ecosystems, at levels that may cause negative effects to the ecosystem and public health. Although there are many bacteria able to BPA utilization, only a few of them have a strong capacity for its biodegradation. Therefore, it is important to search for new bacteria strains, investigate their BPA biodegradation ability and potential effect of pH and other organic compounds on the process. These tasks have become the object of the present study. The results of our research show that for the newly isolated strains Acinetobacter sp. K1MN and Pseudomonas sp. BG12 after 15 days, with an initial BPA concentration of 100 mg L− 1, the highest BPA removal was achieved at pH 8, while sodium glutamate as a biostimulant best accelerated BPA degradation. Kinetic data for BPA biodegradation by both strains best fitted the Monod model. The specific degradation rate and the half saturation constant were estimated respectively as 8.75 mg L− 1 day− 1 and 111.27 mg L− 1 for Acinetobacter sp. K1MN, and 8.6 mg L− 1 day− 1 and 135.79 mg L− 1 for Pseudomonas sp. BG12. The half-maximal effective concentration (EC50) of BPA for Acinetobacter sp. K1MN was 120 mg L− 1 and for Pseudomonas sp. BG12 it was 123 mg L− 1. The toxicity bioassay (Microtox test) showed that elimination of BPA by both strains is accompanied by reduction of its toxic effect. The ability of tested strains to degrade BPA combined with their high resistance to this xenobiotic indicates that Acinetobacter sp. K1MN and Pseudomonas sp. BG12 are potential tools for BPA removal during wastewater treatment plant.

“…Therefore, it creates a good base for their growth. 42,43 Bacteria living on the surface of activated carbon decompose organic contamination and cause its bio-regeneration. 44 However, we have made the case that potentially pathogenic bacteria may be detached and ushed away with ltrate and for that reason, it creates a severe health safety hazard.…”

“…It is often used for water purification through commercially available filters. Activated carbon can be made from various biological residues giving value to waste [9][10][11]. However, the synthesis of ACs necessitates the carbonization of the material itself and an activation step which can be costly and not environmentally friendly [5].…”

The threat of pharmaceutical residues in natural waters is a pressing concern in both developed and underdeveloped countries. Originating mostly from municipal and farms effluents, pharmaceuticals, poorly eliminated by traditional wastewater treatments enter the environment through sewage treatment plants discharges. Their adsorption on ecological adsorptive materials such as lignin may represent an interesting remediation solution. The present study sets out the sorption capacities and properties of a newly developed lignin-based nanofibrous material for typical pharmaceutical residues (fluoxetine, venlafaxine, ibuprofen, and carbamazepine) found in surface waters. This green biomaterial showed, in addition to its high recovery yield, excellent reusability through desorption (more than 90% recovered). As an example, adsorption levels reached 78 mg/g for adsorption of fluoxetine compared to 5-10, 49 and 75-80 for unfunctionalized silica, zeolites and ionexchange resins respectively. The innovative approach reported therein perfectly meets the concept of circular economy sought in modern societies.
