Figure 7
Protease and Pectate lyase activity of X. citri subsp. citri str. 306, and X. citri subsp. citri str. Aw12879. (A) Protease activity was tested by inoculating 1 μl culture on 10% milk agar plates at 28°C for 6 days. Zone of clearance was used as the measure of protease activity. (B) Pectate lyase activity was tested by inoculating 1 μl culture on Hildebrand’s agar medium at 28°C for 6 days. More pitting can be seen on medium at pH 8.5 for XccA strain compared to Xcaw.
