Fig 5. Optimal conditions of purified rhLY and hLY for their antibacterial activity.

Fig 5

(A) The optimal temperatures of the rhLY and hLY against M. lysodeikticus were measured in phosphate buffered saline (pH 7.18) at 25°C, 40°C, 60°C, and 80°C respectively. (B) The optimal pH values of the rhLY and hLY for the antibacterial activity was measured in phosphate buffer with different pH values (from 2–12), separately. hLY, commercial hLY; rhLY, purified rhLY. The experiment for each group was repeated at least three times, and the results were presented as mean ± S.D.
