Summary: This study isolated nine Gram-negative, motile and rod-shaped bacteria from raw milk microbiota in Germany. Through phenotypic and chemotaxonomic characterization, the strains were identified as two novel species, Pseudomonas kielensis and Pseudomonas baltica. These findings contribute to our understanding of the microbial diversity in raw milk.

Summary: Research showed that the growth and persistence of rhizobacteria in soils are highly affected by moisture stress. Specifically, four Pseudomonas strains isolated from the root-soil interface of rice and maize exhibited differential gene expression in response to different moisture levels during water deprivation. This study also demonstrated that inoculating Arabidopsis plants with these Pseudomonas strains can protect against drought stress, with PS2 strain showing higher resistance compared to the others.

Summary: The O-specific polysaccharide (OPS) was isolated from the lipopolysaccharide of Pseudomonas sp. Strain L1, an endophytic bacteria found in Lolium perenne plants in an industrial area in Southern Poland. Chemical methods, mass spectrometry, and NMR spectroscopy were used to study the structure of the high-molecular-weight O-PS fraction. It was found to consist of tetra-saccharide units composed of specific residues.

Summary: The aim of this study was to collect and assess data on the interaction of maize genotypes and beneficial microorganisms. A small plot field trial was conducted over three consecutive years to observe the effects of biostimulant treatments on yield, grain moisture content, grain dry-matter content, and nutritional value of kernels. The results showed that the treatment with biostimulants, in addition to seasonal effects, genotype, and soil nutrient supply, had an impact on grain yield and characteristics determining kernel nutritional value. The interaction between genotypes and interacting microorganisms is of specific importance.

Summary: Inoculation with plant growth-promoting rhizobacteria (PGPR), such as Pseudomonas sivasensis 2RO45, can improve crop productivity by modifying the taxonomic structure and functional dynamics of the rhizosphere microbiome. This study found that P. sivasensis 2RO45 did not significantly alter the diversity of the native soil microbiota, but it increased the abundance of plant beneficial microorganisms and enhanced the metabolic activity of the microbial communities in the canola rhizosphere. The study provides new insights into PGPR-canola interactions for sustainable agriculture development.

Summary: This study calculated the antibiotic resistance profiles of Enterococcus faecium, E. faecalis, and E. durans isolated from traditional sheep and goat cheeses in a border area of Slovakia with Hungary. E. faecalis showed higher resistance compared to E. durans and E. faecium, with high resistance to rifampicin and vancomycin. E. durans and E. faecium also exhibited resistance, with a high percentage of multidrug-resistant strains.

Summary: The behavior of trace metals, specifically cadmium, in volcanic soils can vary significantly, especially in areas where agriculture is causing anthropogenic contamination. Factors such as substrate age and climate elevation can influence the retention capacity of cadmium in soils, with older volcanic soils having a weaker sorption capacity. This can potentially lead to the transfer of cadmium into the food chain through soil microorganisms.

Summary: This study aimed to investigate the sensitivity of parameters such as active carbon and nitrogen mineralisation potential to different agricultural management practices compared to total organic carbon and total nitrogen. The research found that active carbon and nitrogen mineralisation potential are valuable soil biochemical parameters providing detailed information on carbon and nitrogen dynamics, especially in terms of depth distribution and seasonal dynamics, making them more sensitive indicators for agricultural management practices.

Summary: Soils are essential for agriculture and ecosystem services, and their management should focus on improving quality and resilience. The SoilCare project developed the concept of soil-improving cropping systems (SICS) as a holistic approach to promote sustainable and profitable soil management. The adoption of SICS by stakeholders was monitored and evaluated for environmental, sociocultural, and economic effects. The project emphasized the importance of understanding local dynamics in Europe-wide assessments and highlighted the role of economic considerations and social factors such as trust in the uptake of SICS. The results pointed to the need for coherent policies to support a transition to more sustainable agricultural practices.
