Figure 5. WT-T strains do not produce myxovirescin.

Production of myxovirescin, also known as antibiotic TA, was monitored using a zone of inhibition assay with E. coli DH5α. Myxovirescin was produced by WT-Y variants (panel A), but not WT-T variant (B). (C) Like WT-T, myxovirescin was absent in asgB, but present in dkxG and xre228 mutants. Production was delayed in xre228.
