Abstract

65 strains of endophytic actinomycetes were isolated from Achyranthes bidentata, Paeonia lactiflora, Radix Platycodi and Artemisiae argyi. Active strains of inhibiting penicillin-resistant staphylococcus aureus were screened from these strains and some were identified preliminarily. The results showed that 12 strains among these 65 strains of endophytic actinomycetes were able to suppress penicillin-resistant staphylococcus aureus. Through the observation on morphology of mycelium and phylogenetic analysis of 16S rDNA, a strain belongs to the genus Glycomyces and most other as the genus Streptomyces.
