Effect of lysozyme treatment on the transformation efficiency the C. saccharobutylicum Ch2 (∆hsdR1hsdR2hsdR3) strain. Lysozyme (at a concentration of 150 μg/ml) was added in the culture medium when the A600 reached a value of 0.6 (see “Methods”). Incubation time varies between 5 and 50 min. The time point at t = 0 min correspond to an experiment without lysozyme added
