“…In contrast, five genera present in very low amounts before ICPB ( Acinetobacter , Methylophilus , Pseudomonas , Acidovorax and Flavobacterium ) were found to be highly abundant in the carriers after ICPB. Previous studies found that Acinetobacter could degrade a variety of polycyclic aromatic hydrocarbons 38 and that Methylophilus could degrade bisphenol A 39 . Pseudomonas has been shown to have good tolerance to pentachlorophenol 40 .…”

BACKGROUND Intimately coupled photocatalysis and biodegradation (ICPB) is a novel wastewater treatment technology with potential applications in the degradation of bio‐recalcitrant compounds. Although visible light has some advantages over UV light in the ICPB technology, it has never been used to treat 2,4,6‐trichlorophenol (2,4,6‐TCP)‐contaminated wastewater with this approach. RESULTS TiO2/sponge composites with good photocatalytic activity under visible light were prepared and used as biofilm supports to develop a novel ICPB system. The latter showed highly efficient degradation properties and could mineralize 2,4,6‐TCP, with performances superior to those of the individual biological and photocatalytic systems. The removal of 2,4,6‐TCP using the ICPB system reached almost 100% after 4 h, whereas the mineralization rate approached 83% after 12 h. The key feature of the presented ICPB method is that photocatalytic reactions can occur after detachment of biofilms from the outer surface of the composite, and the resulting photocatalytic products are biodegraded by the protected biofilms inside the composites. The interior of the composites exhibited a marked enrichment in Acinetobacter, Methylophilus, Pseudomonas, Acidovorax and Flavobacterium species, which played an important role in the ICPB system. CONCLUSIONS This study introduces a new bio‐photocatalytic degradation system and provides insight into the mechanism of chlorophenol‐contaminated wastewater treatment using ICPB. © 2022 Society of Chemical Industry (SCI).

“…This partially explains the higher abundance of BPA-G in rat urine, since BPA-G was mainly excreted through urine. Firmicutes had shown a obviously positive correlation with the BPA degradation in Gonghu Bay sediment, and high concentrations of BPA can accelerate the BPA removal by Firmicutes (Yuxuan Liu et al 2020). This suggests that Firmicutes may have the ability to biodegrade BPA.…”

Many studies have investigated the effect of bisphenol A (BPA) exposure on gut microbial community changes, while the influence of gut microbiota on metabolism of BPA in organisms remains not well known. To explore this, in this study, Sprague-Dawley rats were intermittently (a 7-day interval) or continuously dosed by oral gavage at 500 µg BPA/kg bw/day for 28 days. Under a 7-day interval BPA exposure, the metabolism of BPA in rats and gut microbiota structure did not change greatly with dosing time. In contrast, following continuous BPA exposure, the relative abundances of Firmicutes and Proteobacteria in rat gut were significantly increased, and the alpha diversity of rat gut bacteria was greatly reduced. Meanwhile, the mean proportion of BPA sulfate to total BPA in rat blood was gradually decreased from 30 (day 1) to 7.4% (day 28). After 28 days of continuous exposure, the mean proportion of BPA glucuronide to total BPA in rat urine elevated from 70 to 81%, and in rat feces the mean proportion of BPA gradually decreased from 83 to 65%. Under continuous BPA exposure, the abundances of 27, 25, and 24 gut microbial genera were significantly correlated with the proportion of BPA or its metabolites in rat blood, urine, and feces, respectively. Overall, this study first demonstrates that continuous BPA exposure disrupted the rat gut microbiota community, which in turn altered the metabolism of BPA in rats. This finding contributes to the better understanding of metabolism of BPA in humans.
