摘要：

The crude enzyme extracts from five actinomycetes selected from a cerrado soil presented very good endochitinolytic activity when compared to a commercial chitinase. Exochitinase and chitobiase activities were also detected. They were identified as Streptomyces, but could not be characterized to species level, probably corresponding to new ones. The crude extracts, obtained from growth on fungal mycelium plus chitin of three of the strains, have shown a very pronounced activity against phytopathogenic fungi. In tests using growing cells, all five strains were active. These data suggest that these strains are potential biocontrol agents.
