Erysiphe alphitoides is a worldwide distributed causal agent of the oak powdery mildew. This work deals with using molecular methods to study the community of micromycetes on the leaves of pedunculate oaks invaded with parazitic fungus.

This final thesis deals with evaluation of microbial air pollution in breeding of laying hens at the university. The aim was to determine the methodology of sampling of microorganisms from the atmosphere using available techniques inspired by sampling procedures for other environments. The goal of the thesis was to identify microorganisms in collected samples with the Sanger sequencing method and to assess their potential impact on the health of the people working in such envitonment. The closing part includes a proposition of adequate measures to reduce the risk of occupational illnesses in this particular working environment.

Diploma thesis deals with relationship between the sustainability of buildings and indoor climate. The aim of the diploma thesis was to design the air conditioning system for operating theaters. In the experimental part the aim was to provide total microorganisms counts and total count of micromycetes on samples taken from filters. The work is divided into three parts: theoretical, design and experiment.
