Straw is an important agricultural raw material with application in agriculture, energy sector and other fields of activity. A major impact on reduction of the straw quality is that of an excessive content of microbiological agents caused by improper storage. By simulation of different conditions of storage the development of microorganisms (moulds and yeasts) was determined in the straw of wheat under different water content. Total content of microorganisms varied in a wide range from 103 up to 105 CFU/g. The excessive amount of these microorganisms results not only in a reduction in the quality of raw material due to the development of biodegradable processes, but also causes an increase of hygienic risks in the nearby area.
