A comprehensive characterization of the culturable mycobiota associated to all stages of lignocellulosebased
composting was achieved. A total of 77 different isolates were detected, 69 of which were identified
on the basis of the 5.8-ITS region sequencing. All the isolates were assigned to the phyla Ascomycota
and Basidiomycota, with prevalence of the Sordariomycetes (19) and Eurotiomycetes (17) classes.
Penicillium was the most represented genus (11 species), while the species Gibellulopsis nigrescens and
Microascus brevicaulis were detected at all the composting stages and showed the highest relative abundances.
Fungal diversity decreased as the process proceed, while similarity between fungal communities
associated to different samples were maximal for those phases closely connected chronologically and
showing similar biological activity degree. Thus, the structure of the lignocellulose-based composting
mycobiota can be divided into two major stages corresponding to bio-oxi...
