“…Bacteria belonging to the family Actinomycetaceae are important natural sources of antimicrobial drugs [ 4 , 5 , 6 ]. The species of terrestrial bacteria belonging to this family, particularly the genus Streptomyces, have been demonstrated to prolifically produce diverse bioactive compounds currently sold in the market and prescribed for clinical use [ 4 , 7 , 8 , 9 ]. These free-living, saprophytic microorganisms could be found in diverse environments such as rain forests, lake and ocean sediments, estuaries, as well as deep ocean trenches, lake mud, beach sands, and sponges [ 5 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”
