The aim of this study was to investigate in vitro and model the effect of temperature (T) and water activity () conditions on growth and toxin production by some toxigenic fungi signaled in cheese. , , , , , , , were considered they were grown under different T (0-40 °C) and (0.78-0.99) regimes. The highest relative growth occurred around 25 °C; all the fungi were very susceptible to and 0.99 was optimal for almost all species (except for , = 0.96). The highest toxin production occurred between 15 and 25 °C and 0.96-0.99 . Therefore, during grana cheese ripening, managed between 15 and 22 °C, ochratoxin A (OTA), penitrem A (PA), roquefortine-C (ROQ-C) and mycophenolic acid (MPA) are apparently at the highest production risk. Bete and logistic function described fungal growth under different T and regimes well, respectively. Bete function described also STC, PA, ROQ-C and OTA production as well as function of T. These models would be very useful as starting point to develop a mechanistic model to predict fungal growth and toxin production during cheese ripening and to help advising the most proper setting of environmental factors to minimize the contamination risk.

The highest hemolytic activity of M. morganii cultivated in urine with low urea concentration (23 and 82 mmol/liter) was observed between 3rd and 4th hours of post-inoculation, while in urine with standard urea level (117 mmol/liter), the activity was observed at 5th hour of post-inoculation.

Micromycetes from the genus Alternaria are commonly found in plant food raw materials, and their produced emerging mycotoxins (EMT) pose a risk to human health. Based on polyphase taxonomy, we studied the species composition of the Alternaria spp. population in samples of Russian grain and berries; non-toxinogenic species of Alternaria of the Infectoriae section and toxinogenic species of the Alternaria section were found.

Burkholderia gladioli produces a yellow-pigmented toxin called toxoflavin, and causes disease on a variety of plants. Previous studies have suggested that the pathogenicity of B. gladioli is regulated by an N-acyl-l-homoserine lactone (AHL)-mediated quorum sensing (QS) system.
