title: Weekly variation of fungal colonies in the atmosphere of Palencia (Spain) throughout the year 1992.
abstract: We have carried out a qualitative and quantitative study of the fungal colonies developed in two different culture media: Czapecdox and Sabouraud, throughout the year 1992 in Palencia city. A volumetric trap was used. We collected daily samples of aerovagans spore from the atmosphere through a cellulose esther filter, half of which was cultivated on Petri dishes. The following genera were identified: 26 Deuteromycetes (54%), four Zygomycetes (28%), and three bacteria, which along with Actinomycetes, reached 18% of all the registered colonies. Fifty-two percent of the colonies were developed in Czapecdox culture medium and 48% in Sabouraud medium. Most of the bacteria were grown in Sabouraud medium. The highest number of colonies recorded belonged to the following three genera: Mucor (25%), Aspergillus (23%) and Penicillium (16%). Most colonies were grown in autumn (32%), while spring was the second most frequent season when 28% of the colonies were registered.
