Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Boosting strawberry yield and fruit sweetness with humic substances and biofertilizer in soilless cocopeat-based culture

Jurnal Ilmiah Pertanian, 2023
Farmers usually apply more chemical fertilizers to enhance the yield of strawberries in soilless culture. Humic substances and biofertilizers are now considered essential nutrient sources in sustainable agriculture.

Physiological Effects of Five Different Marine Natural Organic Matters (NOMs) and Three Different Metals (Cu, Pb, Zn) on Early Life Stages of the Blue Mussel (Mytilus galloprovincialis) [PDF]

, 2017
Metals are present in aquatic environments as a result of natural and anthropogenic inputs, and may induce toxicity to organisms. One of the main factors that influence this toxicity in fresh water is natural organic matter (NOM) but all NOMs are not the

Dual Role of Humic Substances As Electron Donor and Shuttle for Dissimilatory Iron Reduction

Environmental Science and Technology, 2018
Dissimilatory iron-reducing bacteria (DIRB) are known to use humic substances (HS) as electron shuttles for dissimilatory iron reduction (DIR) by transferring electrons to HS-quinone moieties, which in turn rapidly reduce Fe(III) oxides.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

The effect of pH on the binding of heavy metal ions with humic substances and hymatomelanic acids of peats

Учёные записки Казанского университета: Серия Естественные науки, 2017
The values of the dissociation constants (–COOH and –OH) of humic substances and hymatomelanic acids have been determined by the potentiometric titration method. It has been shown that hymatomelanic acids are enriched in phenolic groups compared with the

Atmospheric HULIS: How humic-like are they? A comprehensive and critical review [PDF]

Atmospheric Chemistry and Physics, 2006
A class of organic molecules extracted from atmospheric aerosol particles and isolated from fog and cloud water has been termed HUmic-LIke Substances (HULIS) due to a certain resemblance to terrestrial and aquatic humic and fulvic acids.

Study of Hydrophobic Domains in Humic Acids [PDF]

, 2008
Fyzikálně-chemická povaha hydrofobních domén huminových kyselin byla studována z několika hledisek. K objasnění významu fluorescenčních spekter byly vzorky podrobeny sekvenční frakcionaci, která pomohla k částečnému objasnění vlivu vodorozpustných složek,
