Summary: This study investigated an integrated remediation approach combining white rot fungal augmentation and nano-zerovalent iron (nZVI) activated persulfate oxidation to enhance the degradation of polycyclic aromatic hydrocarbons (PAHs) in soil. The results showed that the sequential treatment significantly enhanced the removal of phenanthrene, anthracene, and benzo[a]pyrene, indicating the coupled effects of chemical oxidation and microbial degradation can accelerate the removal of PAHs.

Summary: PAHs, a class of organic priority pollutants, pose significant public health and environmental concerns due to their carcinogenic, genotoxic, mutagenic, and cytotoxic properties. With increased awareness of their negative effects on the environment and human health, research on eliminating PAHs from the environment has exponentially increased. Various environmental factors, such as nutrients, microorganisms present and their abundance, and the nature and chemical properties of PAHs, affect the biodegradation of PAHs. While bacteria and fungi have garnered the most attention for their biodegradation capacity, a comprehensive understanding of microbial communities and their enzymatic and biochemical properties is crucial for successful PAH degradation. This review aims to comprehensively discuss the latest findings and advancements in the microbial bioremediation of PAHs to enhance the broader understanding of PAHs bioremediation in the environment.

Summary: In this study, a white-rot fungus Phanerochaete sordida YK-624 was used to enhance the biodegradation of high molecular weight and persistent PAHs. The addition of nonionic surfactants significantly improved the degradation of benzo(a)pyrene. This finding suggests that P. sordida YK-624 has the potential for bioremediation of persistent PAHs.

Summary: In recent years, there has been significant progress in the study of thermal transformation of waste into valuable materials such as biochar. High-temperature processes can lead to the formation of toxic polycyclic aromatic hydrocarbons (PAHs). However, the pyrolysis process can also result in the formation of derivatives containing oxygen, nitrogen, or sulfur, which may have higher toxicity than parent PAHs. The bioavailability of PAHs is an important parameter in the agricultural application of carbonaceous materials.

Summary: This study investigated the bacterial community of the Elizabeth River using both culture-based and culture-independent methods, and identified potential candidates for bioremediation of PAH contaminants. The results showed the presence of PAH-degrading bacteria in the sediment, and a divergence in the microbial community between highly contaminated and less contaminated sites. The study highlights the importance of both culture-based and culture-independent methods in identifying promising bacterial candidates for precision bioremediation.

Summary: The study found microplastics and other anthropogenic microparticles in bivalves from San Francisco Bay, with significant variations in abundance between different sites, and no correlation between the number of microparticles and PAH concentrations. Bivalves may be suitable as bioindicators for microplastic levels in sediment, but not in surface water.

Summary: This study investigated the use of Chlorella vulgaris for bioremediation of different PAHs and their impact on the growth and photosynthesis of C. vulgaris. It was found that C. vulgaris could efficiently remove PAHs, with varying abilities depending on the structure of the PAHs. PYR had the most pronounced toxic effect on C. vulgaris, while NAP and ANT had less impact on the photosystem II performance.
