Fusarium moniliforme is the predominant fusarium species in the grain mycoflora of corn grown in the northern Caucasus, accounting for 95% of fusarium isolates. Eighty-five Fusarium moniliforme strains were grown on a grain substrate and checked for the presence of fumonisins (B1 + B2 + B3) by indirect solid-phase enzyme immunoassay. All strains were(More)
The formation of mycotoxins by microscopic fungi was studied during experimental storage of freshly harvested corn in cobs and grain at a 26--35% humidity level. During the corn storage in cobs aflatoxins, kojic acid and zearalenon and during the corn storage in grain zearalenon and ochretoxin A were detected in corn. Mycotoxins we found in maximum amounts(More)
The results of toxicologo-hygienic examinations, which were conducted within the framework of integrated medical and biological assessment of genetically modified rootworm Diabrotica spp.--protected and glyphosate tolerant maize event MON 88017, are presented. Analysis of morphological, hematological, biochemical parameters and system (sensitive) biomarkers(More)
The frequency of occurrence and toxigenicity of various strains of Aspergillus flavus (663 stairs) and of Fusarium spp. (459 strains) isolated from grain of various crops from four grain-producing areas were studied. The analysis of mycotoxins in 1038 grain samples (wheat, rye, rice and corn) and in 58 samples of sun flower seeds collected from commercial(More)
The occurrence of deoxynivalenol (DON) and zearalenone in 495 samples of food wheat, barley and rye collected from different regions of Russia, and in 633 samples of fresh harvested wheat from Krasnodar region in 1993 and 1994 was surveyed. DON was detected in 97% of fresh harvested wheat samples in 1993, exceeding maximum tolerated level MTL) in 69% of(More)
The results of toxicologo-hygienic examinations, which were conducted within the framework of integrated medical and biological assessment of genetically modified rootworm Diabrotica spp.-protected maize event MIR604, are presented. Analysis of morphological, hematological, biochemical parameters and system (sensitive) biomarkers has not confirmed any toxic(More)
The distribution zearalenon (ZL) in products of processing of contaminated wheat, barley and maize grains was is investigated. Results of the data analysis on the investigation of an actual nutrition of the population in Russia is presented; the share of products of processing of contaminated wheat, barley and maize grains as part of the total ration was(More)
The review summarizes the literature data on distribution of nitrogen-containing mycotoxins (alkaloids) among Penicillium and Aspergillus fungi infesting grain and products of grain processing. Particular attention in given to clavins (ergotalkaloids) and tremorgens (roquefortine, verruculogen, penitrems).
Ambient air pollution with flour dust (FD) and microorganisms, including microscopic fungi, was studied; the single concentrations of FD under emission plumes were 0.12-0.17 mg/m3; the total content of mould, field, and storage fungi was 700 +/- 30, 671 +/- 19, and 29 +/- 3, respectively. The maximum allowable concentrations for FD were ascertained; the(More)
