Nocardia argentinensis

Nargenicin (136) is an antibiotic isolated from Nocardia argentinensis. In the biosynthetic studies of nargenicin (136) a pentaketide precursor (133) was incorporated into 136 without modification of the stereochemistry and E-olefine via cis decaline system (135). The incorporation of the tetraene precursor (134) indicates that the decaline system (135) would be generated by the enzymatic Diels-... 

High frequency of DHSS degrading actinomycetes confirmed their reputation for potent biodegraders. However, the biodegradation rates were rather slow (Figure 1). Only Streptomyces fradiae and Nocardiae argentinensis completed primary biodegradation of DHSS within 15 days under test conditions (Table 2).
