ABSTRACT

Physicochemical and mycological analyses of "Pastilla" papers were performed. Average was 0.915, while pH, dry matter and salt concentration were 5.86, 71.4% and 1.26%, respectively. Total number of lungal isolates studied was 187. Among these, 104 (55.6%) belonged to the genus Penicillium, with P. awanflogriseum as major species (51.9 % of Penicilium isolates, i.e. 28.8% of total fungi), followed by P. viridicatum (11.7% of total isolates). 8.5% of total fungi belonged to the genus Aspergi/lus even though they were only present in summer time. Other important mould genera frequently recovered were Cladosporium, Fusarium and Trichoderma (6.4, 5.8 and 4.3 % of total fûngi, respectively). Yeasts amounted to 10% of total fungi, the most frequent genera being Candida and Sac-charomyces (3.2% of total fungi for each).
