Summary: The study found that the addition of humic acid (HA) can significantly enhance the biodegradation efficiency of Mycobacterium sp. NJS-1 on pyrene and induce a new degradation pathway. Furthermore, HA also alters the ultrastructure of bacterial cells, promoting their growth and reducing the space between cells, thereby further improving the biodegradation of pyrene.

Summary: In this study, the absorption, distribution, metabolism, and excretion of polycyclic aromatic hydrocarbons (PAHs) in humans were investigated. It was found that all the PAHs were rapidly absorbed and excreted in urine within a short period of time. The fractional urinary excretion of PAH metabolites ranged from 0.07% to 11.3%, with a half-life of 3.4 to 11.0 hours. Two-compartment models successfully described the toxicokinetic characteristics of each PAH.

Summary: This study conducted whole-genome sequencing of two novel bacterial strains, Klebsiella michiganensis EF4 and K. oxytoca ETN19, to investigate their genomic functions and degradation pathways of phenanthrene and pyrene. The EF4 strain degraded approximately 80% of phenanthrene and 60% of pyrene after 28 days of cultivation. The combination of EF4 and ETN19 showed even higher phenanthrene degradation efficiency, following a first-level kinetic model with a half-life of approximately 6 days. The two bacterial genomes contained enzymes and gene clusters associated with PAHs degradation, as well as transcription factors that regulate the expression of PAHs degradation genes and enzymes.

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: The present study focuses on the phenanthrene degradation ability of the manglicolous fungus Trichoderma sp. CNSC-2 isolated from the Sundarban mangrove ecosystem in India. The study reveals that the extracellular lignolytic enzymes released by the fungus play a significant role in the degradation process. Optimization experiments showed that the degradation efficiency of phenanthrene can be enhanced by adjusting pH, nutrient sources, and the concentration of Cu2+. The study also identified the genes responsible for the production of extracellular and intracellular enzymes, as well as the possible metabolic pathways of phenanthrene degradation. Additionally, the laccase enzyme, which is induced by the presence of phenanthrene and Cu2+ ions, was found to be highly stable and active under certain conditions.

Summary: This study investigates the solubilization ability of mixed systems of polymers and surfactant micelles on PAHs. It is found that the addition of anionic polymers can accelerate the solubilization ability of cationic surfactant micelles, while delaying the solubilization ability of nonionic surfactant micelles. Additionally, the solubilization capacity of the mixed systems is enhanced as the polymer concentration increases within a certain range.

Summary: In this study, a BaP-degrading strain Pannonibacter sp. JPA3 was isolated from oil well production water, which could remove 80% of BaP at an initial concentration of 100 mg L-1 after 35 days of culture. The metabolites BaP-4,5-dihydrodiol, BaP-4,5-epoxide, 5-hydroxychrysene, and 2-hydroxy-1-naphthoic acid were identified in the biodegradation process. A dioxygenase model was built and molecular docking was performed to investigate the interaction mechanism between BaP and dioxygenase. A hypothesis for the progressive degradation mechanism of BaP by this strain was proposed based on the identification of downstream metabolites. In conclusion, this study provided an efficient BaP degrader and a comprehensive reference for the study of degradation mechanisms at the molecular level.

Summary: This study examined the presence and microcosm activity of Anammox microorganisms in saline-sodic alkaline soil of the former Lake Texcoco. After a period of Anammox enrichment, significant removal of ammonium and nitrite was observed along with the production of dinitrogen. The presence of the Anammox functional gene hzoA was detected, and the phylogenetic analysis showed close relationship to bacteria from wastewater treatment reactors and marine environments. The existence of microorganisms with Anammox activity in extremophile soils is of great interest for understanding the nitrogen cycle.

Summary: This study investigated the antimicrobial resistance profile of ESBL-producing E. coli among food-producing animals in Tamaulipas, Mexico. A total of 200 fecal samples were collected and 5.0% of the strains were confirmed as ESBL producers. High percentage of antimicrobial resistance was observed against gentamicin, tetracycline, and streptomycin. The study suggests that food-producing animals may serve as reservoirs and contribute to the spread of ESBL-producing bacteria.

Summary: In this study, two protease genes, aspII and aspVI, in Amylomyces rouxii were successfully silenced using an RNA interference strategy. The results showed that silencing of aspII had a positive effect on tyrosinase activity, while silencing of aspVI had no significant impact on tyrosinase activity. These findings demonstrate the importance of silencing aspII for obtaining strains with high levels of tyrosinase activity.

Summary: This study used RNA interference to investigate the role of the laccase (lacc2) gene in Pleurotus ostreatus. The transformants of P. ostreatus were classified into light, medium, or severe silencing levels. The silencing of lacc2 resulted in a decrease in laccase activity and affected the growth and development of the fungus. Scanning electron microscopy revealed the presence of toxocyst-like structures, which were related to the formation of fruiting bodies.
