Actinomycetes were isolated from soil in different oil palm plantations. The soil samples were collected from healthy standing palms in areas affected with Ganoderma disease. Four media were used to isolate actinomycetes: Yeast-Malt Extract Agar ISP2 Starch-inorganic salt Agar ISP4 Humic acid-vitamin-Agar HVA and Yeast Extract-Casamino acid Agar YCED. A total of 600 isolates of actinomycetes were obtained. Based on morphological characteristics 568 isolates were Streptomyces and 32 isolates non-Streptomyces. All of the isolates have been tested for antifungal activity against G. boninense in vitro. Results indicated that 81 isolates out of600 had shown positive activity towards G. boninense with Percent Inhibition Radial Growth PIRG values more than 80.

Abstract

Actinomycetes were isolated from soil in different oil palm plantations. The soil samples were collected from healthy standing palms in areas affected with Ganoderma disease. Four media were used to isolate actinomycetes: Yeast-Malt Extract Agar ISP2 Starch-inorganic salt Agar ISP4 Humic acid-vitamin-Agar HVA and Yeast Extract-Casamino acid Agar YCED. A total of 600 isolates of actinomycetes were obtained. Based on morphological characteristics 568 isolates were Streptomyces and 32 isolates non-Streptomyces. All of the isolates have been tested for antifungal activity against G. boninense in vitro. Results indicated that 81 isolates out of600 had shown positive activity towards G. boninense with Percent Inhibition Radial Growth PIRG values more than 80.
