Abstract

SILVA, Dianny Carolyne Vasconcelos da et al. Isolation and screening of filamentous fungi from soil of agroforestry systems in the municipality of Bom Jardim (PE) for the ability to produce hydrolytic enzymes. Rev. bras. Bot. [online]. 2011, vol.34, n.4, pp. 607-610. ISSN 0100-8404.  http://dx.doi.org/10.1590/S0100-84042011000400014.

This study aimed to isolate and identify fungi from soil of agroforestry systems and to evaluate the enzymatic activity of these fungi. These were isolated by successive dilution technique and evaluated for their ability to degrade starch, cellulose and caseine. Eleven species of anamorph fungi (Hyphomycetes) distributed in five genera were identified: Aspergillus, Cladosporium, Curvularia, Fusarium and Penicillium. The species studied did not show satisfactory amylolytic activity. Cladosporium cladosporioides (Fres.) De Vries and Penicillium chrysogenum Thom had higher enzyme relation index (ERI) for protease and cellulase. Among the species studied six showed higher Relative Enzymatic Index (IRE) for cellulase in comparison to the other enzymes.

Keywords : amylase; cellulase; protease.
