“…Higher temperature promoted BPA degradation within the range of temperature lower than 37°C. Temperature higher than 37°C inhibited bacterial growth and subsequently affected the BPA biodegradation activity (Kang and Kondo 2002a, b;Zhang et al 2007;Li et al 2012).

Bisphenol A (BPA) is an important monomer in the manufacture of polycarbonate plastics, food cans, and other daily used chemicals. Daily and worldwide usage of BPA and BPA-contained products led to its ubiquitous distribution in water, sediment/soil, and atmosphere. Moreover, BPA has been identified as an environmental endocrine disruptor for its estrogenic and genotoxic activity. Thus, BPA contamination in the environment is an increasingly worldwide concern, and methods to efficiently remove BPA from the environment are urgently recommended. Although many factors affect the fate of BPA in the environment, BPA degradation is mainly depended on the metabolism of bacteria. Many BPA-degrading bacteria have been identified from water, sediment/soil, and wastewater treatment plants. Metabolic pathways of BPA degradation in specific bacterial strains were proposed, based on the metabolic intermediates detected during the degradation process. In this review, the BPA-degrading bacteria were summarized, and the (proposed) BPA degradation pathway mediated by bacteria were referred.

Bisphenol A (BPA) is an endocrine‐disrupting chemical that has caught a lot of attention recently due to its toxicity and ubiquitous presence in the environment. Therefore, removal of BPA from contaminated environments such as water is of high importance. In this study, an alginate/pectin anode containing immobilized laccase is prepared, and the anode is applied in an electroenzymatic oxidation system for BPA degradation. After 4 h, the laccase–alginate/pectin system demonstrates a much higher BPA removal efficiency (95%) than the similar system without immobilized laccase (50%, control system). The effects of humic acids (HA) on BPA degradation are also observed. HA may have accelerated the laccase‐catalyzed coupling reaction between BPA and reactive radical intermediates, which results in increased BPA removal efficiency (92% after 150 min). It is demonstrated that laccase immobilization on an alginate/pectin electrode can greatly enhance BPA removal via electrooxidation. Humic acids which are abundantly present in nature can also make this removal process faster. Overall, this study highlights the great application potential of laccase‐immobilized bioelectrodes for BPA removal in conditions close to real‐life scenarios.

Abstract:The kinetics and mechanisms of ultraviolet photochemical transformation of propylparaben (PPB) were studied. Specific kinetics scavenging experiments coupled with quantum yield determinations were used to distinguish the roles of various reactive species induced by self-sensitized and direct photolysis reactions, and the excited triplet state of PPB ( 3 PPB Ã ) was identified as the most important species to initiate the photochemical degradation of PPB in aquatic environments. The computational results of time-resolved absorption spectra proved that 3 PPB Ã is a highly reactive electron acceptor, and a head-to-tail hydrogen transfer mechanism probably occurs through electron coupled with proton transfer. Physical quenching by, or chemical reaction of 3 PPBÃ with, O 2 was confirmed as a key step affecting the initial PPB transformation pathways and degradation mechanisms. The transformation products were identified and the toxicity evolutions of PPB solutions during photochemical degradation under aerobic and anaerobic conditions were compared. The results indicate that anaerobic conditions are more likely than aerobic conditions to lead to the elimination and detoxification of PPB but less likely to lead to PPB mineralization.
