In-vitro depolymerization of Scutia buxifolia leaf-litter by a dominant Ascomycota Ciliochorella sp.

Scutia buxifolia leaf-litter is recalcitrant to degradation but hosts an assemblage of Ascomycota fungi among which Ciliochorella sp. is the most frequent one. The aim of this work was to analyze the role Ciliochorella sp. plays in degradation of S. buxifolia leaf-litter in-vitro. Decay was assessed...
