The“2+26”cities,suffering the most severe winter haze pollution,have been the key region for air quality improvement in *** prominent nitrate pollution is one of the most challenging environmental issues in this region,necessitating development of an effective control ***,we use observations,and state-of-the-art model simulations with scenario analysis and process analysis to quantify the effectiveness of the future SO_(2)-NO_(X)-VOC-NH_(3) emission control on nitrate pollution mitigation in“2+26”*** on a serious winter haze episode,we find that limited NO_(X)emission reduction alone in the short-term period is a less effective choice than VOC or NH_3emission reduction alone to decrease nitrate concentrations,due to the accelerated NO_(X)-HNO_(3)conversion by atmospheric oxidants and the enhanced HNO_(3)to NO_(3)^(-)partition by ammonia,although deep NO_(X)emission reduction is essential in the long-term *** synergistic NH_(3) and VOC emission control is strongly recommended,which can counteract the adverse effects of nonlinear photochemistry and aerosol chemical feedback to decrease nitrate *** extra benefits will be reduced if the synergistic NH_(3) and VOC reduction is delayed,and thus reducing emission of multiple precursors is urgently required for the effective control of increasingly severe winter nitrate pollution in“2+26”cities.

Desiccation and osmotic resistance mechanism of Cronobacter spp. isolated from powdered infant formula

Food Science and Human Wellness 2024年

作者： Shiqian fu Danliangmin Song Xue qin Lihan Wang Qianyu Zhao Chaoxin man Xinyan Yang Yujun Jiang Key Laboratory of Animal Protein Food Deep Processing Technology of Zhejiang Province， Zhejiang-Malaysia Joint Research Laboratory for Agricultural Product Processing and Nutrition， College of Food and Pharmaceutical Sciences， Ningbo University Key Laboratory of Dairy Science， Ministry of Education， Department of Food Science， Northeast Agricultural University

Cronobacter spp. has strong resistance to desiccation and high permeability in Enterobacteriaceae， and powdered infant formula (PIF) is one of the main contamination routes. In recent years， the contamination of Cronobacter spp. in PIF incidents occur from time to time， causing infant serious diseases or death. In this investigation， matrix-assisted laser desorption/ionization time of flight mass spectrometry was used to identify the phenotypes of 35 Cronobacter strains isolated from PIF and its processing environment. Subsequently， the isolates were evaluated for drying and osmotic pressure tolerance. The results showed that the deactivation rate of the strains ranged from 9.01% to 77.57%， and the highest osmotic pressure condition the strains could tolerate was 6% NaCl. In addition， there was a positive correlation between biofilm formation ability and desiccation resistance. Combined with transcriptomics， Cronobacter spp. can activate biofilm synthesis， produce more trehalose， accumulate betaine and electrolytes to stabilize intracellular structure under the two treatment conditions. 31 and 43 genes were found related to desiccation and permeability resistance， respectively. And some genes (cysM， thuF， ycjO， et al) were found to be associated with two tolerances for the first time.
