Abstract

SOBRAL, LAUREANA V. et al. Antimicrobial and enzymatic activity of anemophilous fungi of a public university in Brazil. An. Acad. Bras. Ciênc. [online]. 2017, vol.89, n.3, suppl., pp.2327-2340.  Epub Oct 26, 2017. ISSN 0001-3765.  https://doi.org/10.1590/0001-3765201720160903.

To the fungal microbiota the UFPE and biotechnological potential enzymatic and antimicrobial production. Air conditioned environments were sampled using a passive sedimentation technique, the air I ratio and the presence of aflatoxigenic strains evaluated for ANVISA. Icelles were to determine the enzymatic activity of lipase, amylase and protease metabolic liquids to determine antimicrobial activity. Diversity was observed in all CAV environments, CFU/m3 ranged from 14 to 290 and I/E ratio from 0.1 to 1.5. The of the fungal genera were: Aspergillus (50%), Penicillium (21%), Talaromyces (14%), Curvularia and Paecilomyces (7% each). Aspergillus sydowii (Bainier & Sartory) Thom & Church presented enzymatic activity and the Talaromyces purpureogenus Samson, Yilmaz, Houbraken, Spierenb., Seifert, Peterson, Varga & Frisvad presented antibacterial activity against all bacteria that all environments present fungal species biodiversity no toxigenic or pathogenic fungi were found, according to ANVISA legislation for conditioned environments and airborne filamentous fungi present potential for enzymatic and antimicrobial activity.

Keywords : Air quality; bacteria; enzymes; filamentous fungi; refrigerated environments.
