“…More recently, Fernandes et al ( 2021 ) reviewed the fate and bioremediation of pharmaceuticals by aquatic environments. Other similar studies have indicated the involvement of the isolated strains in biodegradation of diverse types of compounds, such as polycyclic aromatic hydrocarbons (PAHs), phenanthrene by Comamonas testosteroni strain-T (Olukanni et al 2022 ), and also PAH by fungus Podoscypha elegans Strain FTG4 (Agrawal et al 2021 ), pharmaceutical wastes in treated sewage effluents by Bacillus subtilis 1556WTNC (Al-Gheethi and Ismail 2014 ), methylene blue by textile effluent biotreatment by Acinetobacter pitti ( Ogunlaja et al 2020 ) etc.…”

Industrialization leads to the entry of diverse xenobiotic compounds into the environment. One such compound is paracetamol (APAP), which is emerging as a pharmaceutical and personal care pollutant (PPCP). In this study, the APAP degrading bacterium was isolated by enrichment culture method from the sewage sample. The microscopy, biochemical, and 16S rRNA gene sequence analyzed the isolate PPY-2, which belongs to Bacillus licheniformis , and GenBank assigned accession number MN744328. Physiological and batch culture degradation studies have indicated that the strain involved in the degradation of APAP. The optimum pH for degradation of the PPY-2 was 7.7, whereas the temperature was 25 °C, agitation speed was 142 rpm, and concentration of APAP was 621 mg/L reported, and the optimum temperatures were 42 °C and 32 °C, respectively. Biomass kinetic was studied at optimal physical conditions, which suggested that the specific growth rate ( μ ) was 721 mg/L. The GC–MS chromatogram peaks have detected metabolites, viz., oxalic acid, 2-isopropyl-5-methyl cyclohexanone, and phenothiazine. The study confirmed that Bacillus licheniformis strain PPY-2 exhibits metabolic potential to biodegradation APAP and can be further deployed in bioremediation.
