Abstract

During the experimental period of months March, August, November and January of the years 2002 and 2003, the amount and generic composition of microscopie fungi in soybean heve been monitored. Sampling was done in five takings (25 samples). The aim was to monitor changes in microflora of feedstuff soybean. The highest contamination was detected in the second taking represented by 10 to 10 CFU (colony forming units) of microscopic fungi per 1 gram, followed by first taking in March (2.67.103 CFU.g¹). From the analyzed samples, 26 species belonging to 13 genera of microscopic fungi were isolated and identified. Among the isolated genera, Aspergillus and Penicillium, belonged to the most dangerous fungi, occuring in 67 - 100 % and 50 - 88 % of the samples tested, respectively. Stored cereals can be seriously damaged by these genera owing to grain moulding as well as by production of mycotoxins and allergenes. Species determined as Aspergillus fumigatus, Aspergillus flavus etc. can contaminate and impair the feedstuff soybean.
