Summary: In this study, nonthermal plasma (NTP) irradiation was used to activate traditional CaO and enhance its effectiveness in alkali activation and self-cementation of gold tailings. The NTP-CaO-activated gold tailings showed better solidification/stabilization compared to CaO. NTP irradiation improved the surface characteristics of the calcium activator and facilitated the formation of aluminosilicate geopolymers during self-cementation.

Summary: Recently, the use of low-temperature plasmas and plasma-activated water (PAW) in biological research has gained much attention. This article reviews the composition and properties of PAW prepared by different methods, and finds no significant difference between PAW prepared by plasma treatment and that prepared by mixing the active ingredients. The research also shows that PAW promotes germination and growth of wheat grains, and effectively decontaminates bacteria and yeast.

Summary: This study evaluated the effects of plasma-activated hydrogen peroxide solution (PAH) on the morphophysiology of Staphylococcus aureus biofilms. The results indicated that PAH significantly reduced the population of S. aureus in the biofilms, decreased the thickness and metabolic capacity of the biofilms, while increasing ROS content and DNA fragments of bacteria. PAH treatments were found to be a valuable anti-biofilm technology to reduce foodborne pathogens.

Summary: Nitrogen fixation is a crucial process for various biological and industrial processes, but it is also a major source of carbon emissions globally. In this study, a novel approach using plasma-activated mist (PAM) is proposed for efficient and sustainable nitrogen fixation. The PAM system generates nitrogen-fixation species through the reaction of air plasma and water mist, and the liquid-phase nitrogen fixation product is dominated by NO3-. This system is applied to deliver nitrogen-based nutrients directly to plant roots using an aeroponic system, leading to significant improvements in plant growth.

Summary: A low-temperature and environment-friendly approach using nonequilibrium plasmas with Ti3C2Tx dispersion is demonstrated to generate abundant and stable surface-terminating O groups. The discharge environment of Ar, O-2, and H-2 affects the structural characteristics and electrochemical performance of Ti3C2Tx nanosheets. Ti3C2Tx treated using H-2 plasmas exhibits the best capacitive performance with a capacity of 418.3 F g(-1) at 2 mV s(-1) and maintains 95.88% capacity after 10,000 cycles.

Summary: The species, pathways, and timescales for NH3 production by plasma catalysis over transition-metal wools are determined through experiments measuring plasma-derived species densities. The results show that surface-mediated reactions involving N radicals are responsible for NH3 formation, with Ni and Ag surfaces exhibiting high selectivity to NH3. The presence of catalysts enables higher and more selective conversion of N to NH3 compared to gas-phase reactions alone. These findings demonstrate that surfacemediated reactions among radical N and H species drive NH3 formation in low-temperature atmospheric pressure plasma catalysis.

Summary: The production of NH3 by plasma catalysis over transition-metal wools is determined by measuring plasma-derived species densities and correlating the consumption of these species with NH3 formation. Surface-mediated reactions involving N radicals are responsible for NH3 formation. The selectivity to ammonia drops as the densities of H and H2 decrease for each catalyst. Surface reactions enable higher and more selective conversion of N to NH3 than gas-phase reactions alone.

Summary: This study investigated a novel nonthermal sanitization technique, cold plasma-activated water (PAW), for washing shell eggs. Washing inoculated eggs with PAW achieved a similar microbial reduction as quaternary ammonia (QA) and did not adversely affect the shell structure or cuticle coverage. According to the results, PAW has the potential to be an alternative to commercial sanitizers like QA in the egg-washing industry.

Summary: This study investigated the effect of plasma activated milk powder with 1.3 g/kg nitrite as an alternative to sodium nitrite in stored pork sausages. The results showed that using plasma activated milk powder resulted in higher nitrite and nitrosylhemochrome content, as well as improved redness of the sausages, without compromising the oxidative and microbiological quality of the product. Additionally, the addition of ascorbic acid further reduced nitrite content and extended color stability.

Summary: In this study, the movement trajectories of pathogenic and probiotic Escherichia coli strains were characterized at the landing stage, and their correlation with adhesion patterns and efficiency was investigated. Different bacterial strategies for effective surface colonization were considered based on the obtained results: horizontal strategy characterized by collective directed movements within the horizontal layer, and vertical strategy characterized by individual movement mainly in the vertical direction.

Summary: This study investigated the interaction between L. monocytogenes and sheep cells, and found that the invasion efficiency was influenced by the InlB factor. Different InlB isoforms may contribute to the hypervirulence of certain clonal groups towards ruminants, and L. monocytogenes can effectively multiply once it enters sheep cells.

Summary: This study investigated the occurrence of antimicrobial resistance among Salmonella strains isolated from food products. Multiple serovars of Salmonella with resistance to commonly used antibiotics were identified. Genomic analysis revealed the presence of antibiotic resistance genes within integrons in plasmids or chromosomal islands. Pathogenicity islands were also found in the genomes of the sequenced strains. The emergence of multidrug-resistant Salmonella strains highlights the need for further research on transmission pathways and monitoring of these microorganisms' distribution.

Summary: Magnetic force and gravity are two fundamental forces affecting all living organisms, including bacteria. Magnetic force can be used to counterbalance gravity and create conditions of magnetic levitation on Earth. Under microgravity conditions, magnetic force becomes the sole force that moves bacteria, causing them to accelerate towards areas of the lowest magnetic field. This review discusses the principles, experimental systems, and applications of magnetic force in microbiological studies both on Earth and in space.

Summary: The virulence factor InlB of Listeria monocytogenes interacts specifically with the receptors c-Met and gC1q-R. This study examines the effects of different isoforms of InlB on L. monocytogenes uptake and intracellular proliferation in human macrophages. The isoform idInlB(CC1) exhibits the highest efficiency in macrophage proliferation compared to other isoforms. Pretreatment of macrophages with idInlB(CC1) impairs macrophage functions, decreasing pathogen uptake and improving its intracellular multiplication.

Summary: Listeria monocytogenes is motile at 22 degrees C and non-motile at 37 degrees C. The expression of virulence factors in L. monocytogenes is low at 22 degrees C and up-regulated at 37 degrees C. Motile bacteria show a preference for adhering to the periphery of epithelial cells, while non-motile bacteria are evenly distributed across the cell surface. Motility enhances L. monocytogenes invasion into human cells when combined with up-regulated virulence factor production. Motile L. monocytogenes grown at 22 degrees C and then shifted to 37 degrees C show a significantly higher invasion efficiency compared to non-motile bacteria grown at 37 degrees C.

Summary: In this study, nanotwin structured TiO2 nanotube layers were prepared by electrochemical anodization to form Ce-TNT and V-TNT through surface modification. The efficiency of V-TNT was found to be higher than Ce-TNT and TNT, attributed to its negative surface enhancing interactions with CAF.
