Fifteen actinomycete strains were isolated from Salwa beach in Jazan province, KSA. The isolated marine actinomycete strains were then screened with regard to their potential to generate antibiotics. The most potent of the producer strains was selected and identified. The cultural and physiological characteristics of the strain identified the strain as a member of the genus Saccharomonospora. The nucleotide sequence of the 16S rRNA gene (1.215 kb) of the identified strain evidenced a 98% similarity with Saccharomonospora sp. M8Z39.
