To elucidate the biosynthetic machinery associated with ICZs production in S . sanyensis FMA , PCR using degenerate primers was carried out to clone the FAD - dependent monooxygenase gene fragment for ICZ ring formation , which was used as a probe to isolate the 34 . 6 - kb DNA region containing the spc gene cluster .
