Biological Activity

Linearmycin A is a polyene antibiotic that has been found in Streptomyces.1 It is active against the bacteria S. aureus and E. coli (MICs = 3.1 and 1.6 μg/disc, respectively), the fungi S. cerevisiae and C. albicans (MICs = 0.1 and 1.6 μg/disc, respectively), and the plant pathogenic fungus A. niger in disc assays (MIC = 0.2 μg/disc). Linearmycin A induces lysis and degradation of B. subtilis as a component of Streptomyces Mg1 extract.2
