FIG. 6.
Comparison of autolytic activities of Xc92 (ΔatlA) and the wild-type strain Xc. An autolysis assay of bacterial cells was carried out as described in Materials and Methods. The cell suspension was incubated at the optimum temperature for the autolytic activity of AtlA (44°C). Open circles represent Xc92 (ΔatlA); closed circles represent Xc.
