Cultivation and characterization of functional-yet-uncultivable phenanthrene degraders by stable-isotope-probing and metagenomic-binning directed cultivation (SIP-MDC)
Environ Int. 2024 Mar 4;185:108555. doi: 10.1016/j.envint.2024.108555. Online ahead of print.ABSTRACTHigh-throughput identification and cultivation of functional-yet-uncultivable microorganisms is a fundamental goal in environmental microbiology. It remains as a critical challenge due to the lack of routine and effective approaches. Here, we firstly proposed an approach of stable-isotope-probing and metagenomic-binning directed cultivation (SIP-MDC) to isolate and characterize the active phenanthrene degraders from petroleum-contaminated soils. From SIP and metagenome, we assembled 13 high-quality metagenomic bins from 13C...

Vitamin E: An assistant for black soldier fly to reduce cadmium accumulation and toxicity
Environ Int. 2024 Mar 1;185:108547. doi: 10.1016/j.envint.2024.108547. Online ahead of print.ABSTRACTCadmium (Cd) is a toxic heavy metal associated with osteoporosis, liver, and kidney disease. The black soldier fly (BSF) Hermetia illucens may be exposed to Cd during the transformation of livestock manure. The BSF has a high tolerance to Cd. In the previous work of the laboratory, we found that vitamin E (VE) may play a role in the tolerance of BSF to Cd exposure. The main findings are as follows: The BSF larvae pretreated with exogenous VE had heavier body weight, lower content and toxicity of Cd under similar Cd exposure...

Occurrence of mycotoxins in meat alternatives: Dietary exposure, potential health risks, and burden of disease
This study aimed to present the occurrence of sixteen mycotoxins in 105 meat alternatives based on wheat, legumes, and vegetables from Italy. The targeted mycotoxins were aflatoxins (AFB1, AFB2, AFG1, AFG2), fumonisins B1 and B2 (FB1, FB2), alternariol (AOH), alternariol monomethyl ether (AME), tentoxin (TEN), ochratoxin A (OTA), zearalenone (ZEN), T-2/HT-2 toxin, deoxynivalenol (DON), enniatin B (ENNB), and beauvericin (BEA). The occurrence of mycotoxins was between 0% (AFB2) - 97.4% (ENNB). Mycotoxin co-occurrence varied from binary combinations up to mixtures of twelve. To assess the dietary exposure and potential healt...

Polystyrene microplastics induce anxiety via HRAS derived PERK-NF- κB pathway
Environ Int. 2024 Mar 4;185:108543. doi: 10.1016/j.envint.2024.108543. Online ahead of print.ABSTRACTExposure to environmentally hazardous substances is recognized as a significant risk factor for neurological associated disorders. Among these substances, polystyrene microplastics (PS-MPs), widely utilized in various consumer products, have been reported to exhibit neurotoxicity. However, the potential association of PS-MPs with abnormal anxiety behaviors, along with the underlying molecular mechanisms and key proteins involved, remains insufficiently explored. Here, we delineated the potential mechanisms of PS-MPs-induced...

Online ahead of print.ABSTRACTClimate change is endangering the soil carbon stock of alpine grasslands on the Qinghai-Tibetan Plateau (QTP), but the limited comprehension regarding the mechanisms that sustain carbon storage under hydrothermal changes increases the uncertainty associated with this finding. Here, we examined the relative abundance of soil microbial keystone taxa and their functional potentials, as well as their influence on soil carbon storage with increased precipitation across alpine grasslands on the QTP, China. The findings indicate ...

Household fuel and direct carbon emission disparity in rural China
In this study, we revealed the historical changing trend of the disparity in household cooking and heating activities and associated carbon emissions in rural China. The study found that the poor had higher total direct energy consumption but used less modern energy, especially in cooking activities, in which the poor consumed 60 % more energy than the rich. The disparity in modern household energy use decreased over time, but conversely the disparity in total residential energy consumption increased due to the different energy elasticities as income increases. Though per-capita household CO2 and Black Carbon (BC) emission...

Urbanization influences the indoor transfer of airborne antibiotic resistance genes, which has a seasonally dependent pattern
Environ Int. 2024 Mar 1;185:108545. doi: 10.1016/j.envint.2024.108545. Online ahead of print.ABSTRACTOver the last few years, the cumulative use of antibiotics in healthcare institutions, as well as the rearing of livestock and poultry, has resulted in the accumulation of antibiotic resistance genes (ARGs). This presents a substantial danger to human health worldwide. The characteristics of airborne ARGs, especially those transferred from outdoors to indoors, remains largely unexplored in neighborhoods, even though a majority of human population spends most of their time there. We investigated airborne ARGs and mobile gene...
