Actinobacteria are widely distributed in many environments and represent the most important trigger to occupant respiratory health. Health complaints, including hypersensitivity pneumonitis of workers, were recorded a mushroom compost facility (MCF). The studies on airborne bacteria carried out find possible microbiological source these symptoms. Culture analysis bioaerosols collected different location MCF was performed. An assessment indoor microbial exposure revealed bacterial flora bioaerosol represented by Bacillus, Geobacillus, Micrococcus, Pseudomonas, Staphylococcus spp., actinobacterial strain with white aerial mycelium. thermotolerant same morphology repeatedly isolated from locations MCF: air, sample, solid surface production hall. On base complex morphological, chemotaxonomic, phylogenetic characteristics, isolate has been classified as Nocardiopsis alba. Dominant position N. alba environment may an indicator microorganism bioaerosol. bioavailability creates potential risk for health protection tract and/or skin is strongly recommended.
