Fig. 6. Second-round screening to obtain high yield strains in shake flasks.
UN-C183 and UN-C137 showed significantly higher production of tylosin than the wild-type strain SF-3. The wild-type strain SF-3 was used as the control. Data are shown as mean ± SD from three independent replicates. “*” p < 0.05; “**” p < 0.01.
