From: Stable expression plasmids for Streptomyces based on a toxin-antitoxin system
Enzyme production by the different strains. Amylase (A) and Xylanase (B) production by S. lividans wt-pKC796, S. lividans ΔTA-pKC796 and S. lividans ΔTA-pKC796-Tox transformed with pNAnti-Amy (A) and pNAnti-Xyl (B) after 4 days of culture in YES medium supplemented with 3% xylose. 10 μL of supernatant was loaded in each track. On the left, a diagram of the expression plasmids is shown.
