Effects of short-term exposure to elevated atmospheric CO2 on yield, nutritiona...

Aim: Legumes are vital to agroecosystems and human nutrition, yet climate change is compromising their nutritional value. This study aims to assess how a one-month exposure to elevated CO2 (eCO2) impacts biomass yield, mineral profile, gene expression, and the soil microbiome of common bean plants (Phaseolus vulgaris L.). Methods: Phaseolus vulgaris L. was grown in field conditions under ambient CO2 (control, a...

Establishing the effects of climate and soil on the nutritional composition of ...

Legumes contribute to sustainable agriculture by reducing fertilizer use, enhancing nitrogen fixation, and with high species diversity (~20,000 species). Spain is a leading EU producer, yielding up to 30,000 tons of different legume varieties annually. The Mediterranean climate, particularly in regions like Andalusia, is under increasing pressure from climate change, with extreme temperature variations and drou...

Making waves

With the global concerns on antibiotic resistance (AR) as a public health issue, it is pivotal to have data exchange platforms for studies on antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment. For this purpose, the NORMAN Association is hosting the NORMAN ARB&ARG database, which was developed within the European project ANSWER. The present article provides an overview...

Measurement of the impact of antibiotic resistance discharge in wastewater and ...

Antibiotic resistance represents a serious threat to human health and a relevant environmental contaminant. Antibiotic-resistant bacteria (ARB) and harboured antibiotic resistance genes (ARGs) were described in different settings, mainly in clinical contexts, but also in wastewater treatment plants or agricultural soil. In the environment, the general pollution context may favour the persistence or proliferatio...

Insight into phylogenomic bias of blaVIM-2 or blaNDM-1 dissemination amongst ca...

Objectives: Pseudomonas aeruginosa (P. aeruginosa) are ubiquitous opportunistic pathogens that combine intrinsic and acquired multidrug resistance phenotypes. Due to different types of acquired genes, carbapenem resistance has been expanding in this species. This study hypothesised that the spread of carbapenem resistance among P. aeruginosa is influenced by phylogenomic features, being distinct for different g...

The impact of HPP-assisted biocontrol approach on the bacterial communities’ dy...

Traditional foods are increasingly valued by consumers, whose attention and purchase willingness are highly influenced by other claims such as ‘natural’, ‘sustainable’, and ‘clean label’. The purpose of the present study was to evaluate the impact of a novel non-thermal food processing method (i.e., HPP-assisted biocontrol combining mild high hydrostatic pressure, listeriophage Listex, and pediocin PA-1 produci...

Dissemination of metallo-β-lactamase-producing pseudomonas aeruginosa in Serbia...

This nationwide study aimed to investigate the molecular characteristics of metallo-β-lactamase (MBL)-producing Pseudomonas aeruginosa in Serbia, underlying resistance mechanisms, the genetic context of detected MBL genes, and the clonal relationship between isolates harboring genes-encoding MBL. Overall, 320/5334 isolates collected from 2018 to 2021 were identified as P. aeruginosa. Carbapenem-resistant P. aer...

Effect of copper and zinc as sulfate or nitrate salts on soil microbiome dynami...

The exposure of soil to metals and to antibiotic resistant bacteria may lead to the progressive deterioration of soil quality. The persistence of antibiotic resistant bacteria or antibiotic resistance genes in soil can be influenced by the microbial community or by soil amendments with metal salts. This work assessed the effect of soil amendment with copper and zinc, as sulfate or nitrate salts, on the fate of ...

Fate of pseudomonas aeruginosa and blaVIM in soil under selective pressure by c...

A rationale for the high limits of quantification of antibiotic resistance gene...

The determination of values of abundance of antibiotic resistance genes (ARGs) per mass of soil is extremely useful to assess the potential impacts of relevant sources of antibiotic resistance, such as irrigation with treated wastewater or manure application. Culture-independent methods and, in particular, quantitative PCR (qPCR), have been regarded as suitable approaches for such a purpose. However, it is argu...
