Summary: A novel promoter engineering-based strategy was developed to create efficient PNP-mineralizing bacteria by introducing a complete PNP biodegradation pathway from Pseudomonas sp. strain WBC-3 into the genome of a biosafety and soil-dwelling bacterium Pseudomonas putida KT2440. Five strong promoters were identified from P. putida KT2440 and independently inserted into the genome to create a mutant strain with the highest PNP degradation rate and strong tolerance against high concentrations of PNP, demonstrating complete and efficient PNP mineralization. This strategy opens new avenues for creating efficient degraders for bioremediation.

Summary: In this study, a Box-Behnken design was used to optimize the removal of CI Reactive Red 66 in artificial seawater. The combination of eco-friendly bio-sorbents and acclimated halotolerant microbial strain proved to be effective. The best bio-sorbent was found to be macro-algae and cuttlebone, and the selected microbial strain was identified as Shewanella algae B29, which showed rapid dye removal capabilities. The optimization process achieved a decolourization yield of 91.04% under specific variable values.

Summary: Phenols are highly soluble in water and can pollute various sources of water and soil, negatively impacting plant germination and human and animal health. Researchers investigated the use of novel bacteria isolated from sewage sludge for the biodegradation of phenol in wastewater. Three bacterial strains, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Klebsiella variicola, were found to efficiently degrade phenol at high concentrations and remove it from the environment. These strains also facilitated the germination of soybean and faba bean seeds treated with phenol, making them potential candidates for bioremediation in industrial wastewater and phenol-contaminated soils.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
