Abstract
The purpose of this study is to evaluate the efficacy of metabolites produced form Streptomyces rimosus in controlling the growth of sapwood - inhabiting fungi. In order to carry out this task, the following specific fungi were tested : sapstain fungi - Ceratocystis pilifera, Ceratocystis piceae, and Aureobasidium pullulans ; mold fungi - Trichoderma hazianum, Trichoderma viride, Penicillium cirtrinum, and Aspergillus niger. Based on the tests, the following observations can be drawn. 1. The conidial germination of sapstain and mold fungi was completely inhibited leaving a clear zone around the paper disc treated with metabolites. The best inhibition was observed in A. pullulans plate and the least in T. viride. 2. Concentration of SB medium for the production of metabolites from St, rimosus affected antifungal activity of metabolites against sapwood - inhabiting fungi. Metabolites prepared from 1/3
