A broad-spectrum fluorescent probe, which can be applied to monitoring H2S in various biological systems, has been rationally designed and synthesized. This specific probe was localize the endogenous living Raw264.7 macrophage cells, HepG2 H9C2 cells. At same time, successfully visualized CBS- CSE-induced production monitored CBS CSE activity could serve as a powerful molecular imaging tool further explore physiological function mechanisms of animal systems.
Anoxygenic phototrophic Fe(II)-oxidizing bacteria (photoferrotrophs) are suggested to have contributed the deposition of banded iron formations (BIFs) from oxygen-poor seawater. However, most studies evaluating contribution photoferrotrophs Precambrian Fe(II) oxidation used freshwater and not marine strains. Therefore, we investigated physiology mineral products by photoferrotroph Rhodovulum iodosum. Poorly crystalline Fe(III) minerals formed initially transformed more goethite over time....
Abstract The formation of cell‐(iron)mineral aggregates as a consequence bacterial iron oxidation is an environmentally widespread process with number implications for processes such sorption and coprecipitation contaminants nutrients. Whereas the overall appearance easily accessible using 2‐D microscopy techniques, 3‐D internal structure remain obscure. In this study, we examined formed during Fe( II ) by nitrate‐reducing Acidovorax sp . strain BoFeN1 combination advanced techniques. We...
A novel rhodamine based probe with a unique six-membered spirocycle was rationally designed for detection of Hg2+ greatly improved selectivity, sensitivity, and photostability. The has been shown to be suitable imaging in living cells mapping distribution cell–EPS–mineral aggregates under anoxic conditions.
Evidence for Fe(II) oxidation and deposition of Fe(III)-bearing minerals from anoxic or redox-stratified Precambrian oceans has received support decades sedimentological geochemical investigation Banded Iron Formations (BIF). While the exact mechanisms remains equivocal, reaction with O2 in marine water column, produced by cyanobacteria early oxygenic phototrophs, was likely. In order to understand role Fe(III) BIF, we must first know how planktonic respond ferruginous (anoxic Fe(II)-rich)...
In this study, we couple iron isotope analysis to microscopic and mineralogical investigation of speciation during circumneutral Fe(II) oxidation Fe(III) precipitation with photosynthetically produced oxygen. the presence cyanobacterium Synechococcus PCC 7002, aqueous (Fe(II)aq) is oxidized precipitated as amorphous oxyhydroxide minerals (iron precipitates, Feppt), distinct isotopic fractionation (ε56Fe) values determined from fitting δ56Fe(II)aq (1.79‰ 2.15‰) δ56Feppt (2.44‰ 2.98‰) data...
ABSTRACT Nitrous oxide (N 2 O) is a potent greenhouse gas and can be biotically emitted from soils, water, the less recognised plant leaves. Leaves produce N O may host O‐reducing microbes that use it as respiratory substrate, potentially mitigating climate warming. This study examines ecophysiology of reducers in phyllosphere. Anoxic microcosm experiments, quantification reduction kinetics, analysis nosZ gene governing were conducted to assess activity presence leaf epiphytes various canopy...
The plant microbiota is believed to be an accessory genome that extends functions, forming holobionts together with the host plant. Plant disease resistance, therefore, inextricably linked microbiota, which play important roles in growth and health. To explore relationship between we investigated tobacco microbiome of two varieties contrasting disease-resistance levels bacterial wilt black shank diseases. Comparative analysis indicated resistant variety assembled a distinct higher network...
A Gram reaction-negative, weakly motile, non-spore-forming, rod-shaped, aerobic bacterium designated strain JLT832(T) was isolated from surface water of the central Pacific Ocean and formed yellow colonies on rich organic (RO) medium. The oxidase-negative catalase-positive. Acid produced mannitol, glucose, sucrose, lactose, sorbitol, maltose, (+)-trehalose d-fructose. No acid d-(+)-xylose. major cellular fatty acids were C(18 : 1)ω7c, C(14 0) 2-OH C(16 0). polar lipids sphingoglycolipid,...
A recent global scale study found that mining-impacted environments have multi-antibiotic resistance gene (ARG)-dominated resistomes with an abundance similar to urban sewage but much higher than freshwater sediment. These findings raised concern mining may increase the risk of ARG environmental proliferation. The current assessed how typical multimetal(loid)-enriched coal-source acid mine drainage (AMD) contamination affects soil by comparing background soils unaffected AMD. Both...
A Gram-negative, non-motile, rod-shaped bacterial strain, JLT354-W(T), that accumulates poly-beta-hydroxybutyrate granules was isolated from the South China Sea. Phylogenetic analysis based on 16S rRNA gene sequences showed strain related to members of genera Antarctobacter, Sagittula, Oceanicola and Loktanella; levels similarity between JLT354-W(T) above were less than 92.0 %. The predominant fatty acid C(18 : 1)omega7c (83.1 %); significant amounts 0) (7.9 %) C(12 1) 3-OH (3.7 also...
Abstract A series of Cu 2+ probe which contains 9 probes have been synthesized and established. All the were using Rhodamine B as fluorophore, conjugated to various differently substituted cinnamyl aldehyde with C=N Schiff base structural motif their core moiety. The structure-property relationships these investigated. change optical properties, caused by different electronic effect steric recognition group, has analyzed systematically.

Antimony (Sb) and arsenic (As) are two hazardous metalloid elements, the biogeochemical cycle of Sb As can be better understood by studying plant rhizosphere microorganisms associated with mine waste. In current study, samples three types waste-Sb tailing, waste rocks, smelting slag-and adapted plants were collected from Qinglong mine, southwest China. 16S rRNA was sequenced used to study composition microbial community. The most abundant phylum in all Proteobacteria, followed Bacteroidota,...
