Harmful cyanobacterial blooms (HCB) have become a common issue in freshwater worldwide. Biological methods for controlling HCB are relatively cost effective and environmentally friendly. The strain of ascomycete GF6 was isolated from a water sample collected from the estuarine zone of the eastern part of the Gulf of Finland.

- Bostrycoidin, a pigment from fungi, has pharmacological significance and indicates Fusarium infections in crops and soils.
- Researchers used density functional theory (DFT) to investigate the molecular structure and properties of bostrycoidin, analyzing its most stable geometry and energy levels of various conformers.
- The study successfully modeled the vibrational and electronic absorption spectra, with the calculated longest-wavelength transition aligning well with experimental results at approximately 498 nm.
The quality of food is one of the emergent points worldwide. Many microorganisms produce toxins that are harmful for human and animal health. In particular, mycotoxins from Fusarium fungi are strictly controlled in cereals.

- * Optical techniques show promise for identifying these diseases quickly and cost-effectively, but it's essential to find specific spectral markers that indicate contamination.
- * This study utilized various spectroscopy methods and chemometric analysis to differentiate ergot-infected grains using their infrared and reflection spectra, aiming to improve detection in wheat production.
Article Synopsis
- This paper explores how optical and vibrational spectroscopies can help identify and study the T-2 mycotoxin.
- It uses computer simulations to analyze the structures and properties of T-2 toxin and compares them to a similar compound, 3-deacetylcalonectrin, to find unique spectral features.
- The findings suggest that understanding the structure and spectroscopic characteristics of these molecules can improve detection methods for T-2 toxin and its metabolites.
