Abstract

From 5 forest soil samples, the isolation frequency of oligotrophic Actinomycetes was investigated with nutrient and minimal media. The frequency of soil Actinomycetes by the minimal media. The frequency of soil Actinomycetes by the minimal media of DHV, WA, BA and NA was similar to the value by HV nutrient medium. In addition, different Actinomycetes were isolated from all the media used in this experiment and then their growth were tested on nutrient (Bennett's agar) and minimal media(WA). In consequent, the number of different Actinomycetes from minimal media was 26.1 strains, whereas the number of from nutrient medium (HV) was 26.6 strains. Furthermore, the percentage of facultative and obligate strains among the oligotrophic Actinomycetes was 90% and 10%, respectively.
