3.1 Isolation and identification of fungi
Samples of soil and litter were collected from the Campina Biological
Reserve in order to isolate fungal strains to be screened for colorant
production. The samples were subjected to the serial dilution method and
plated in Sabouraud agar medium to obtain isolated colonies. We obtained
184 colonies of filamentous fungi (55 from litter and 129 from
superficial soil). The micromorphological characteristics of the
isolates were analyzed and a predominance of unidentified isolates was
observed. However, among those that could be identified, the generaAcremonium , Aspergillus and Penicillium were the
most frequent.
