We studied the effect of dimethyl sulfoxide (DMSO) on the biochemical and physiological parameters of S. cerevisiae yeast cells with varied energy metabolism and antioxidant status. The wild-type cells of varied genetic backgrounds and their isogenic mutants with impaired antioxidant defences (Δsod mutants) or response to environmental stress (ESR) (Δmsn2, Δmsn4 and double Δmsn2msn4 mutants) were used.

Bacteria that are widespread in soil, water, and plant material include the group, which plays an important role in biodegradation and the nutrient cycle and is a major factor determining ecological balance. This group includes, among others, the foodborne pathogen (herein referred to as ).

- - This study explored using iodine-containing fertilizers to enhance the iodine content in rye plants grown for cow fodder, focusing on the best application method, form, and dosage.
- - Findings revealed that iodine application, especially via soil using potassium iodide (KI), effectively increased iodine levels in rye biomass, particularly in neutral soil conditions, even at low doses (2.5 kg/ha).
- - Additionally, iodine fertilization improved rye's biological quality by elevating sugar, chlorophyll, and to some extent, protein and antioxidant levels.
Zinc oxide nanoparticles (ZnO NPs), due to their antibacterial effects, are commonly used in various branches of the economy and can affect rhizobacteria that promote plant growth. We describe the effect of ZnO NPs on two model bacteria strains, and , that play an important role in the environment. The MIC (minimum inhibitory concentration) value determined after 48 h of incubation with ZnO NPs was more than 1.

Antioxidant and antimicrobial properties were tested in water (W), ethanol-water (EW), and glycerol-water (GW) extracts from the buds. These plant organs contain relatively large amounts of minerals, especially Fe.
