Article Abstract
We enriched and characterized a biodesulfurizing consortium (designated as MG1). The MG1 consortium reduced the total sulfur of diesel by 25 % and utilized each of the diesel-born compounds dibenzothiophene (DBT), benzothiophene (BT), 4-methyldibenzothiophene (4-MDBT) and 4, 6-dimethyldibenzothiophene (4, 6-DMDBT) as a sole sulfur source. MiSeq analysis revealed compositional shifts in the MG1 community according to the type of the sulfur source. A DBT-grown MG1 culture had , , and as the most abundant genera. When diesel or 4, 6-DMDBT was provided as a sole sulfur source, and spp. were the most abundant. In the BT culture, spp. were the key biodesulfurizers, while , and spp. dominated the 4-MDBT-grown consortium. MG1 also utilized 2-hydroxybiphenyl (the product of the 4S biodesulfurization pathway) where spp. uniquely dominated the consortium. The data improves our understanding of the sulfur source-driven structural adaptability of biodesulfurizing consortia.

Elevated acidity from natural and anthropogenic sources can be a significant stressor for plants, affecting essential processes such as nutrient uptake and growth. While low pH (< 4) is generally considered stressful for plants, differential impacts of distinct acid types-organic versus inorganic, strong versus weak-on plant growth and development remain unclear. To address this knowledge gap, we evaluated the responses of two Brassicaceae species to organic (acetic) and inorganic (hydrochloric, sulfuric) acids at three pH levels (pH 2.

As the world's largest producer of crude steel, China's iron and steel industry (ISI) is one of the major sources of both air pollutant and carbon dioxide (CO) emissions in the country. To better track emission patterns and assess the synergistic reduction potential under various policies during the 14 Five-Year Plan period, a high-frequency, smokestack-level and national emission database was developed that covers both air pollutants (i.e.

Simultaneous measurements of dimethylsulfide (DMS) and isoprene in seawater and the overlying atmosphere were conducted in the tropical western Pacific Ocean during February-March 2017. Surface seawater exhibited a strong correlation between DMS and dimethylsulfoniopropionate (DMSP), with similar spatial distributions, whereas dimethylsulfoxide (DMSO) displayed an opposing trend. Latitudinal and vertical profiles of DMS, DMSP, and isoprene revealed their pronounced dependence on biological factors, particularly in subsurface layers.

Antimony trisulfide (SbS) has emerged as a promising inorganic semiconductor for optoelectronics due to its distinctive anisotropic crystal structure and suitable bandgap (∼1.7 eV). While hydrothermal synthesis remains challenging for achieving high crystallinity and controlled morphology, we developed an innovative dual‑sulfur precursor strategy utilizing sodium thiosulfate (STS) and thioacetamide (TAA) at a 7:2 M ratio with SbCl.

Air pollution is a significant public health issue that impacts lung health, particularly in vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory conditions. Both natural and anthropogenic sources of air pollution give rise to a variety of toxic compounds, including particulate matter (PM), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and polycyclic aromatic hydrocarbons (PAHs). Exposure to these pollutants is strongly associated with the development and exacerbation of respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and idiopathic pulmonary fibrosis (IPF).
