This thesis entitled "Effect of gloeosporium rot as gaseous constituents of apple varieties" deals with microorganisms in terms of storage and processing. Characterized mainly epiphyte microflora occurring on apples, mainly sponge Gloeosporium spp. Specifies how does this affect rot on the gaseous components in the fruit, how it affects breathing and the formation of ethylene and what risks may cause the processing. Features mold and products of their metabolism, concentrations and health risks. The conclusion of this paper describes the experimental determination of the invading microorganisms fruit during storage.

The work deals with the evaluation of nutrients and epiphytic microflora content in selected grass species Lolium perenne L., Phleum pratensis L., Festuca arundinaceae Schreb. and Lolium multiflorum Lam. X Festuca arundinacea Schreb. 2017 and 2018 at Vatín. The task was to determine the effect of fertilization doses by digestate, harvest year and species on organic nutrient content and epiphytic microflora. The content of nitrogenous substances, fats, fiber, ADF and NDF was evaluated from organic nutrients. The statistically significant (P <0.05) was the year for the effect on the crude protein content. Statistical significance (P <0.05) for fat content was demonstrated only in the species. For the proportion of fiber, ADF and NDF in fodder, the year of harvest, the type of fodder and the fertilizer variant had a statistically significant effect (P <0.05). The second evaluated area in forage was the epiphytic microflora. Only a fertilizer variant was statistically significant in CPM (P <0.05). The year of harvest and the fertilization variant were statistically significant (P <0.05) for BMK. The incidence of Enterobacteriaceae Enterobacteriaceae, the total number of micromycetes and yeasts was not statistically significant from any point of view. In fungi, fertilization was a statistically significant (P <0.05) variant. The effect of digestate fertilization on the amount of nutrients and microorganisms has not been evident.
