ARRUA ALVARENGA, Andrea Alejandra et al. Presence of filamentous fungi in composite yerba mate and efficiency of culture media for isolation Aspergillus. Investig. Agrar. [online]. 2016, vol.18, n.1, pp.50-56. ISSN 2305-0683.  https://doi.org/10.18004/investig.agrar.2016.junio.49-55.

Yerba mate is a plant native to South America and high consumption in Paraguay. The composite yerba mate, with added herbs is high consumption and market acceptance. During its cultivation and processing, components of the composite yerba are exposed to fungal attack, including those belonging to the genus Aspergillus spp, producing potentially harmful mycotoxins for humans. In order to determine the most efficient medium for isolating fungi Aspergillus spp., five different formulations were compared. Ten genera of fungi were identified and within the genus Aspergillus four sections: Flavi, Nigri, Circumdati and Fumigati. It was concluded that specific media for isolating Aspergillus MAAS, was the most efficient for this purpose.
