TABLE 3.

Levels of pectate lyase activity in E. carotovora subsp. carotovora strains^a

Strain	Relevant characteristics	Pel activity
AC5006	AhlI⁺ ExpR1⁺ ExpR2⁺	0.44 ± 0.02
AC5091	AhlI⁻ ExpR1⁺ ExpR2⁺	0.01 ± 0.01
AC5099	AhlI⁻ ExpR1⁻ ExpR2⁺	0.05 ± 0.01
AC5117	AhlI⁻ ExpR1⁺ ExpR2⁻	0.47 ± 0.03
AC5118	AhlI⁻ ExpR1⁻ ExpR2⁻	0.56 ± 0.06

Bacterial cultures were grown at 28°C in minimal salts medium containing sucrose (0.5%, wt/vol) to a concentration of ca. 200 Klett units. Cultural supernatants were used for enzyme assays. Pel activities are expressed in A₂₃₅/A₆₀₀ per min. The values are means ± standard deviations for three repetitions.
