In today’s environment where the society attaches great importance to environmental pollution, there has been a certain amount of research at home and abroad to explore the solutions to pollution of the large amount of polluting and persistent harmful substances that remain in nature. And most people think that it is necessary to solve the problem of pollution in two ways. (1) Energy: without discussing other energy sources, we will only discuss the main oil of today’s energy. The treatment and use of this energy will cause pollution to a certain degree, and it has been overexploited. The exploration of new energy sources and increasing the use of natural energy such as wind and solar energy are the main research directions today. (2) Degradation of existing pollutants: nowadays, due to the rapid development of various industries, attention to environmental pollution has reached a point that cannot be ignored. As a kind of brominated flame retardant, polybrominated diphenyl ethers are widely used because of their low price and stable chemical properties, mostly in electronic appliances, building materials, textiles, furniture, and other products. But the substance is extremely harmful. This article focuses on the degradation treatment of tetrabromodiphenyl ether, which is one of the polybrominated diphenyl ethers that are long-lasting and difficult to be degraded in the environment. It has become an emerging persistent organic pollutant due to its toxicity, persistence, and bioaccumulation. Based on the reduction and debromination of zero-valent iron, the effect of debromination of tetrabromodiphenyl ether is explored under the coupling effect of the nanosized iron powder with the smaller particles of zero-valent iron and vitamin B12. The experimental results in this paper show that when the dosage of nanoiron powder is between 0.0 g/L and 0.15 g/L, according to the degradation diagram, the reaction rate is continuously strengthened with the increase of nanoiron powder. When the dosage of nanoiron powder is 0.15 g/L-1.0 g/L, the effect will be weakened with the increase of the concentration. Therefore, an increase in the concentration of nanoiron powder will promote the progress of the debromination reaction. But when it reaches a certain level, the reaction rate will gradually decrease until it stops.

“…The P. tomentosa forest, aged 16, grows on West Campus of Agricultural University of Hebei, Baoding, China. The leaf material preparation and strains isolation were conducted following the method described by Zhao et al [21]. The phyllospheric microbiota was subcultured for several times to obtain phenotypically different yeast colonies as many as possible.…”

“…Incubation suspensions were treated on a rotary shaker at 20ºC and 150 rpm for 1 h. Then, 1 mL supernate was extracted from the suspensions for removal efficiency analysis by applying gas chromatograph (Agilent Technologies 6890N) coupled with a micro-electron capture detector (Agilent Technologies, USA; GC-μECD). The capillary column, thermal settings and other procedure details were performed following the method described by Zhao et al [21].…”

As a class of synthetic organic compounds widely used in varieties of industrial products, polybrominated diphenyl ethers (PBDEs) have attracted increasing attention for the properties of toxicity, bioaccumulation and persistence. In this paper, the phyllospheric yeast strain capable of aerobic degradation of 4-brominated diphenyl ether (BDE-3) was originally isolated from Populus tomentosa. Based on the morphological properties and the ITS sequence analysis, the obtained yeast was identified as Wickerhamomyces anomalus and designated Y1. The endurance ability of Y1 to BDE-3 exposure was determined by BDE-3 concentration gradient experiment. BDE-3 removal efficiency analysis was conducted by applying GC-μECD with initial BDE-3 content of 40 mg/L. Results showed Y1 could remove 83.58±2.60% of 40 mg/L BDE-3 in 3-day aerobic incubation. The tolerance range of pH and NaCl concentration were determined for further engineering application. It could be the first report about PBDEs degradation by yeast strain, isolated from the phyllosphere of P. tomentosa at the non-contaminated site of a subastral ecological niche, and might be advantageous in comprehensive exploitation of phytoremediation.

“…The research showed that Nocardioides could not only decompose cellulose, lignin, polycyclic aromatic hydrocarbon and related molecular organic components, but also could degrade toxic compounds such as fungicide, herbicide and insecticide, and can degrade petroleum hydrocarbon compound [53][54]. Sphingomonas had the biodegradation capacity of an aromatic compound, but as the knowledge of Sphingomonas was gained relatively later, its ecological and economic value potential were great [55]. Phycicoccus can degrade xenobiotics, degrade ritalinic acid and related substances [56].…”

To study the removal performance of a constructed rapid infiltration (CRI) system and its microbial community characteristics, we took the demonstration project of a CRI system that has successfully operated for 15 years as an example, aiming to analyze the CRI system's removal performances for COD, NH 4 +-N, TN and TP. Meanwhile, high-throughput sequencing technology was used for the first time to study the microbial community diversity and structure in the CRI system. The results showed that the average removal efficiencies for COD and NH 4 +-N were 75.52% and 92.94%, and the average removal efficiencies for TN and TP were respectively 39.74% and 42.78%. High-throughput sequencing technology indicated that a variety of bacterial phyla were found in CRI's bacterial communities, including Bacteroidetes, Actinobacteria and Acidobacteria, among which Proteobacteria dominated. At the genus level, a spatial variation was illustrated for the diversity and structure of bacterial communities. The dominant genera on the surface layer (0 cm) of CRI were mainly Nocardioides, Sphingomonas, Bryobacter and other microorganisms that can degrade organic matter, and the dominant genera in the inside (30-120 cm) were mainly microorganisms that play an important role in removing nitrogen. This study provided a theoretical basis for the long-term operation of a CRI system.
