Abstract

A new strain of Streptomyces sp., strain RFCAC02, was isolated from the gut of the Pacific chub mackerel Scomber japonicus peruanus This strain produces a variety of secondary metabolites. Further bioinformatic analysis revealed the presence of biosynthetic gene clusters putatively coding for compounds related to the polycyclic tetramate macrolactams (PTMs).

Highlights

  • The uncontrolled use of antibiotics has created conditions for the emergence of multidrug-resistant pathogenic microorganisms, which is challenging health systems worldwide

  • Pairwise genome comparison confirmed a close relationship between strain RFCAC02 and S. avicenniae MCCC 1A01535, showing an average nucleotide identity (ANI) of 80.58%, a value below the accepted cutoff threshold for species delimitation of 95% [14]

  • An antiSMASH v4.0 search [15] revealed the presence of 20 putative biosynthetic gene clusters, including clusters coding for the production of polycyclic tetramate macrolactams (PTMs)
