Abstract
- The microbiological quality of 23 grain samples of wheat and barley harvested in the North Caucasus in 2019 was analysed on the basis of the percentage of grains infected by fungi and the amounts of trichothecene-producingFusariumDNA andAlternariaDNA. The mycotoxins produced by these fungi were also determined.AlternariaandFusariumfungi were the predominant fungi in the mycobiota of grain, accounting for at 93% and 14% of the observed fungi, respectively. Alternariol produced byAlternariafungi was detected in 65% of samples, and its content (11-675 ppb) was positively correlated with the abundance of fungi of sectionAlternariain grain.F. langsethiaewas found in wheat grain from the Chechen Republic for the first time. The T-2 toxin produced by this fungus was found in 25% of samples, and its content in one barley grain reached 650 ppb, which exceeded the permitted level for this mycotoxin. The mycotoxins deoxynivalenol and zearalenone, which are mainly produced byF. graminearum, were also identified in 13% of the grain samples. The positive correlation between the amounts of both these mycotoxins and the DNA of Tri-Fusariumwas established.
