Figure 2. Antibacterial activities of OstrinLysC against Gram-positive and Gram-negative bacteria. *: semidiameter of clear zone. OstrinLysC displayed antibacterial activity against two Gram-positive bacteria species and two Gram-negative bacteria species: 5 mm of semidiameter clear zone against B. subtilis and S. aureus. 3 mm of semidiameter clear zone against P. aeruginosa and 1 mm of semidiameter clear zone against E. coli. 10 μl of OstrinLysC (100 μg/mL) was used for assay.
