Streptomyces are a genus of Actinobacteria capable of producing structurally diverse natural products. Here we report the isolation and characterization of a biosynthetically talented Streptomyces (Streptomyces sp. SD85) from tropical mangrove sediments. Whole-genome sequencing revealed that Streptomyces sp. SD85 harbors at least 52 biosynthetic gene clusters (BGCs), which constitute 21.2% of the 8.6-Mb genome. When cultivated under lab conditions, Streptomyces sp. SD85 produces sceliphrolactam, a 26-membered polyene macrolactam with unknown biosynthetic origin.
