This article has been cited by other articles in PMC. Abstract Mangroves are the tidal forest existing in the intertidal zone and usually considered as the special marine ecosystem. In the present study, actinomycetes were recovered from nine diferent sites at Maowei Sea Mangrove Reserve in Qinzhou Guangxi province, China. Among them, Seventy-four strains were purified for 16s RNA gene sequencing and further characterization. The results indicated that the majority of isolates belonged to the genera Streptomyces, including 17 species. Streptomyces sanyensis was the dominant species
