A PRELIMINARY-STUDY OF THE OCCURRENCE OF ACTIDIONE-RESISTANT FUNGI INSEDIMENTS OF CATALONIAN RIVER MOUTHS (SPAIN) - I - KERATINOLYTIC FUNGI AND RELATED ONYGENALES

Sediments from eight river mouths along the Catalonian coast (Spain) w ere surveyed for keratinolytic fungi and related Onygenales. The actid ione plating technique was employed. Of 532 actidione-treated sediment samples, 268 (50.3%) were positive for the fungi. Altogether, 384 fun gal :;trains from 35 species were isolated from the samples. Narasimhe lla marginospora, Aphanoascus fulvescens, Neoarachnotheca keratinophil a with its anamorph Myriodontium keratinophilum, Narasimhella hyalinos pora, Beauveria alba, Sporothrix schenckii, Chrysosporium lobatum and Gymnoascus littoralis were the predominant species in sediments. Abund ance of N. marginospora was clearly correlated with the degree of wate r pollution with sewage.
