Journal of Environmental Sciences 2024年第3期137卷 195-205页

Antimicrobial resistance in the laying hen production industry has become a serious public health *** antimicrobial resistance and phylogenetic relationships of the common conditional pathogen Enterococcus along the laying hen production chain have not been systematically clarified.105 Enterococcus isolates were obtained from 115 environmental samples (air,dust,feces,fies,sewage,and soil) collected along the laying hen production chain (breeding chicken,chick,young chicken,and commercial laying hen).These Enterococcus isolates exhibited resistance to some clinically relevant antibiotics,such as tetracycline (92.4%),streptomycin (92.4%),and erythromycin (91.4%),and all strains had multidrug resistance *** genome sequencing characterized 29 acquired antibiotic resistance genes (ARGs) that conferred resistance to 11 classes of antibiotics in 51pleuromutilin-resistant Enterococcus isolates,and lsa(E),which mediates resistance to pleuromutilins,always co-occurred with lnu(B).Alignments with the Mobile Genetic Elements database identified four transposons (Tn554,Tn558,Tn6261,and Tn6674) with several ARGs(erm(A),ant(9)-la,fex(A),and optrA) that mediated resistance to many clinically important ***,we identified two new transposons that carried ARGs in the Tn554 family designated as Tn7508 and Tn7492.A complementary approach based on conventional multi-locus sequence typing and whole genome single nucleotide polymorphism analysis showed that phylogenetically related pleuromutilin-resistant Enterococcus isolates were widely distributed in various environments on different production *** results indicate that environmental contamination by antimicrobial-resistant Enterococcus requires greater attention,and they highlight the risk of pleuromutilin-resistant Enterococcus and ARGs disseminating along the laying hen production chain,thereby warranting effective disinfection.

In-situ decorated cobalt phosphide cocatalyst on Hittorfs phosphorus triggering efficient photocatalytic hydrogen production

作者： Abiduweili Sikandaier Yukun Zhu Dongjiang Yang School of Environmental Science and engineering State Key Laboratory of Bio-fibers and Eco-textilesQingdao UniversityQingdao266071China

Hydrogen production through semiconductor-based photocatalytic water splitting is an appropriate strategy to convert solar energy into hydrogen fuels[1].In recent years,metal-free elemental red phosphorus(RP)materials,including amorphous,fibrous,and Hittorfs phosphorus(HP)possessing moderate bandgap and bandstructure have been explored as potential visible-light-driven hydrogen evolution reaction(HER)photocatalyst[2].However,the slow charge migration capacity and sluggish surface reaction kinetics of RP materials have limited their HER efficiency to unsatisfactory *** overcome these limitations and improve the photocatalytic HER efficiency,various strategies,including building heterostructures,morphology control,and surface modification have been investigated[3].For instance,[001]-oriented HP nanorods decorated on polymeric carbon nitride exhibited excellent photocatalytic HER activity,which was attributed to accelerated photo-generated electron-holes transfer along the[001]direction of HP[4].In addition to enhancing the charge transfer ability by morphology regu-lation to allow more electrons to migrate to the surface to participate in HER,loading cocatalysts on RP surface to enhance HER kinetics is another effective strategy for altering HER activity[5].
