“…In a stirred-tank photobioreactor with a microalgal-bacterial consortium, the removal of ketoprofen, acetaminophen, and aspirin mixture was poor with a HRT of 3 days but enhanced greatly with a HRT of 4 days (Ismail et al 2017). Continuous illumination showed the highest removal efficiency.…”

“…Illumination is also important for algae-based systems due to the requirement of photosynthesis for algae growth and the possibility of photodegradation. Previous research showed that continuous illumination was preferred for the removal of analgesic pharmaceuticals but dark condition favored the removal of chlorinated parabens (Ismail et al 2017;Song et al 2017). HRT has been studied most as an important operational parameter, and better PPCP removal was achieved with longer HRT (Ismail et al 2017).…”

Pharmaceuticals and personal care products (PPCPs) consist of a variety of compounds extensively used for the treatment of human and animal diseases and for health or cosmetic reasons. PPCPs are considered as emerging environmental contaminants due to their ubiquitous presence in the environment and high environmental risks. In wastewater treatment plants using conventional activated sludge processes, many PPCPs cannot be efficiently removed. Therefore, there is an increasing need for more effective and cost-efficiency ways of removing PPCPs while treating wastewater. Algae-based technologies have recently attracted growing attentions for their potential application in wastewater treatment and hazardous contaminant removal, which are advantages in reducing operation cost while generating valuable products and sequestrating greenhouse gases at the same time. This work reviews the up-to date researches to reveal potential toxic effects of PPCPs on algae and algae-bacteria consortia, identify mechanisms involved in PPCP removal, and assess the fate of PPCPs in algae-based treatment systems. Current researches suggest that algae and algae-bacteria consortia have great potentials in PPCP removal but more works are required before algae-based technologies can be implemented in large scales. Knowledge gaps are identified and further research focuses are proposed in this review.

“…transforms APAP into 4-aminophenol one of the dead-end metabolite and acetate (Hart and Orr 1975). The Rhodococcus strain degrades APAP into intermediates compounds: 4-aminophenol, hydroquinone and catechol (Ismail et al 2017). Bart et al (2011) purposed the metabolic pathway for the degradation of APAP by D. tsuruhatensis and P. aeruginosa and it was observed that hydroquinone as an intermediate produced during degradation.…”

Background: In this study, the biodegradation of N-acetyl-para-aminophenol also known as acetaminophen (APAP, paracetamol) was studied by bacterial strain Bacillus drentensis strain S1 (accession no. KY623719) isolated from sewage sample. Results: The Bacillus drentensis strain S1 was isolated from the sewage sample using the enrichment culture method. As per our knowledge this is the first Bacillus drentensis strain reported for the degradation of APAP. In this study a 20-L batch reactor was employed for degradation of APAP. The maximum specific growth rate (μ max) was observed at 400 mg/L concentration of APAP. The pilot-scale anaerobic batch reactor of was stable and self-buffered. The degradation in pilot-scale reactor was slow as compared to batch experiments due to fluctuation in pH and exhaustion of nutrients. Design-Expert ® software was used for optimization of conditions for APAP degradation; such as temperature (40 °C), pH (7.0), concentration of APAP (300 g/L) and agitation speed (165 rpm). The FTIR and GC-MS were used to identify the degradation metabolites. The intermediates of degradation like 2-isopropyl-5-methylcyclohexanone and phenothiazine were observed, based on these results the metabolic pathway has been predicted. Conclusions: The optimization, kinetic, batch study and pilot study indicates the potential of Bacillus drentensis strain S1 for degradation of acetaminophen. The experimental design, optimization and statistical analysis were performed by Design Expert ® software. The optimal growth condition for Bacillus drentensis strain S1 was found to be at temperature 40 °C, pH 7, acetaminophen at concentration of 300 (mg/L) and agitation speed 165 rpm. The GC-MS and FTIR was used for identification of metabolites produced during acetaminophen degradation and the partial metabolic pathway for degradation of acetaminophen was also proposed .
