Abstract

Abstract

Eight fungi isolated from Pinus taeda needles under decomposition, from Três Barras region, SC, Brazil, were analyzed in relation to their ability to degrade cellulose and lignin. The staining technique employed congo red on carboxymethylcellulose-agar (CMCA) for cellulose and the Bavendamm test employed malt extract-tanic acid-agar (EMATA) for phenol oxidase. Aspergillus sp. and Cladosporium sp. produced higher activity in CMCA environment, while Trichoderma sp., Pestalotia sp., Exophiala sp. and Phomopsis sp. produced higher activity in EMATA environment. The fungi Stachybotrys sp. and Rhizopus sp. developed in CMCA and EMATA environment, but without noticeable activities, which indicates inability in order to degrade cellulose or phenols in pine needles.

Keywords: Decomposition; fungal physiology; litter.
