The present study revealed the consequences of the interaction of a widely used bioinsecticide and endophyte Metarhizium anisopliae with the hazardous mycotoxin zearalenone (ZEN) as a pure substance and with ZEN as a native component of a crude Fusarium extract. In the environment, microorganisms encounter a mixture of metabolites secreted by other organisms living in the same area, not single substances. The obtained results suggest that M.

The main objective was to compare the sensitivity of Neosartorya spp. isolates to preservatives used in food security applications and to assess the role of metabolic properties in shaping Neosartorya spp.

- The study examined the interaction between the fungicide azoxystrobin (AZ) and the biosurfactant-producing bacteria sp. Kol B3, revealing enhanced antifungal effects against the fungal pathogen IM 6525.
- The combination of AZ and Kol B3 notably inhibited fungal growth, altered hyphal structure, increased membrane permeability, and elevated levels of reactive oxygen species (ROS) in the fungus.
- Changes in biosurfactant production were observed, particularly an increase in iturin synthesis, and a minor degradation of AZ was noted after 72 hours in the co-culture.
Fungi belonging to the genus Neosartorya (teleomorph of Aspergillus spp.) are of great concern in the production and storage of berries and fruit-based products, mainly due to the production of thermoresistant ascospores that cause food spoilage and possible secretion of mycotoxins. We initially tested the antifungal effect of six natural extracts against 20 isolates of Neosartorya spp.

- Microplastics in soil can harm tiny organisms, but researchers wanted to see how they affect a specific fungus while it breaks down herbicides.
- The study found that microplastics alone didn't hurt the fungus much, but the herbicide metolachlor did slow its growth significantly.
- However, when both the microplastics and herbicide were present, the fungus still worked well to break down the herbicide, although the mix changed the fungus's cell structure a bit.
