Occurrence of filamentous fungi in yerba mate discarded in the environment

Yerba mate, Ilex paraguariensis A. St. Hil. (Aquifoliaceae), waste is one of the most common byproducts generated in households southern Brazil due to traditional consumption mate. However, decomposition this by fungi has not been thoroughly evaluated. In order study fungal succession mate residue, 450 samples were evaluated during autumn, winter, and spring, kept for two months a humid chamber (aerobic medium) growth associated filamentous fungi. We morphologically identified means microscopy device taking into consideration only surface-developed mycelia. Twenty-two genera found, which Zygomycota (Rhizopus spp. Mucor spp.) microflora deserve special attention since they growing first 19 days. After period, Deuteromycota (mainly Aspergillus Oomycota (Pythium develop more vigorously, supplanting previous ones. The species Curvularia, Fusarium, Verticillium, Pythium are phytopathogens end up having their inoculum source increased with irregular disposal residue nature. presence numerous genera, known be pathogenic according literature, highlights importance implementing proper practices environment. Improper yerba can result contamination itself but also other commercial crops. Therefore, it imperative that greater paid waste.
