“…These results were in accordance with Eio et al (2015), who found that BPA adsorption by Chlorella sorokiniana were b1%, and the BPA was removed efficiently in algal (Chlorella sorokiniana)-activated sludge bacterial system from 10 mg L −1 to below the detection limit, while that in the monoculture of algal system was 38.5%. Wang et al (2017) performed similar experiments with green microalga Desmodesmus sp. WR1 and achieved removal efficiency of 54% under the lowest initial BPA concentration (1 mg L −1 ) in a 10-day treatment.…”

“…The octanol-water partition coefficient (K ow ) for BPA is 3.40, which means it may be accumulated by algal because of its moderate hydrophobic property (Isobe et al, 2007). Microalgae have been reported to play important role in the fate of EDCs in freshwater aquatic environments (Gattullo et al, 2012;Guo et al, 2017;Hom-Diaz et al, 2015;Nakajima et al, 2007;Ruksrithong and Phattarapattamawong, 2017;Wang et al, 2017). Gattullo et al (2012) studied the removal of BPA by the microalga Monoraphidium braunii to find that approximately 35%-48% of BPA (2-10 mg L −1 ) was removed from wastewater and BPA at the lower concentrations (b4 mg L −1 ) was not toxic for alga.…”

“…In addition, natural organic matter at any concentration scarcely influenced the BPA removal. Wang et al (2017) reported that green microalga Desmodesmus sp. WR1 isolated from municipal wastewater was able to remove BPA (1, 3, 5.5, 13.5 mg L −1 ) with the removal rate ranging from 18% to 57% and BPA was transformed into two products.…”

New phycoremediation of coastal water with BPA occurred during green tide bloom. • N94% of BPA was removed by the greentidal algae U. prolifera. • BPA removal efficiency has positive relationship with light, nutrient and temperature. • High removal efficiency (N94%) was achieved at environmental relevant concentrations. • BPA concentration in green tide bloom area was much lower than that in adjacent area.

“…Chlorella is also one of the most tolerant eight genera [29] and highly tolerant to soluble organic compounds [30][31][32][33]. Wang et al has identified novel pathways for biodegradation of BPA by green alga, while the maximum initial exposure concentration was low to inhibited algal growth [34]. Ji et al used two stains of fresh microalgae for the biodegradation of BPA and utilization of algae under light condition [35].…”

“…BPA was detected in a wide range of environments including landfill leachates [16], industrial wastewater [17], source water and drinking water [18], rivers, seas, and soils [19][20][21][22]. Therefore, special attention has been given to BPA toxicity in these environments [23]. The most common methods to remove pollutants from the environment included photodegradation, photoelectrocatalytic oxidation, oxidation [17] and biodegradation [24].…”

Background: Bisphenol A is an important organic chemical as an intermediate, final and inert ingredient in manufacturing of many important products like polycarbonate plastics, epoxy resins, flame retardants, fooddrink packaging coating, and other. BPA is an endocrine disruptor compound that mimics the function of estrogen causing damage to reproductive organs. Bacterial degradation has been consider as a cost effective and eco-friendly method for BPA degradation compared with physical and chemical methods. This study aimed to isolate and identify bacterial strain capable to degrade and tolerate high concentrations of this pollutant, studying the factors affecting the degradation process and study the degradation mechanism of this strain. Results: YC-AE1 is a Gram negative bacterial strain isolated from soil and identified as Pseudomonas putida by 16S rRNA gene sequence and BIOLOG identification system. This strain found to have a high capacity to degrade the endocrine disruptor Bisphenol A (BPA). Response surface methodology using central composite design was used to statistically optimize the environmental factors during BPA degradation and the results obtained by significant model were 7.2, 30°C and 2.5% for optimum initial pH, temperature and inoculum size, respectively. Prolonged incubation period with low NaCl concentration improve the biodegradation of BPA. Analysis of variance (ANOVA) showed high coefficient of determination, R 2 and Adj-R 2 which were 0.9979 and 0.9935, respectively. Substrate analysis found that, strain YC-AE1 could degrade a wide variety of bisphenol A-related pollutants such as bisphenol B, bisphenol F, bisphenol S, Dibutyl phthalate, Diethylhexyl phthalate and Diethyl phthalate in varying proportion. Pseudomonas putida YC-AE1 showed high ability to degrade a wide range of BPA concentrations (0.5-1000 mg l − 1) with completely degradation for 500 mg l − 1 within 72 h. Metabolic intermediates detected in this study by HPLC-MS were identified as 4,4-dihydroxy-alpha-methylstilbene, p-hydroxybenzaldeyde, p-hydroxyacetophenone, 4hydroxyphenylacetate, 4-hydroxyphenacyl alcohol, 2,2-bis(4-hydroxyphenyl)-1-propanol, 1,2-bis(4-hydroxyphenyl)-2-propanol and 2,2-bis(4-hydroxyphenyl) propanoate. Conclusions: This study reports Pseudomonas putida YC-AE1 as BPA biodegrader with high performance in degradation and tolerance to high BPA concentration. It exhibited strong degradation capacity and prominent adaptability towards a wide range of environmental conditions. Moreover, it degrades BPA in a short time via two different degradation pathways.
