ANALYSIS OF FUNGI OCCURRENCE IN ENERGY CHIPS PILES
Keywords:forestry, wood chips, storage, fungi, relative humidity, temperature
AbstractThis article is focused on the analysis of fungi in energy chips piles. At the same time factors affecting the formation and evolution of fungi were analyzed. The bases for the experiment were nine experimental chips piles produced from wood species: European beech (Fagus sylvatica), European aspen (Populus tremula) and Norway spruce (Picea abies). Wood chips of each particular tree species have been produced from a fresh biomass, biomass stored in half-shade and in opened area. The greatest number of fungi was found in piles 3 - spruce wood chips produced from biomass stored on the meadow, 7 â€“ chips from aspen stored in half-shade and 8 - beech wood chips produced from biomass stored in half-shade. The most represented species were Aspergillus niger and Mucor spinosus. These two species were recorded in seven of nine piles. Presence of Trichoderma koningii was identified only in two piles of chips, which were made from spruce and aspen biomass stored in the opened area.
