TABLE 3.
Toxicity of Cry3A produced by DSM 2803 and 4Q7/pPFT3As to C. scriptaa
| Strain | Mean LC50 (ng/mm2)b (95% fiducial limits) | Slope (± SE) | Amt of Cry3A (% of solubilized protein)c |
|---|---|---|---|
| DSM 2803 | 3.4 (1.75–5.65) | 1.88 ± 0.37 | 7.7 |
| 4Q7/pPFT3As | 4.8 (3.25–6.83) | 1.82 ± 0.25 | 52.9 |
a
Cry3A was solubilized from lyophilized powders of each strain grown on GYS medium and assayed against second instars feeding on leaf discs.
b
These values are not significantly different.
c
This value represents the proportion that Cry3A constituted of the total protein solubilized from the lyophilized powders of these strains.
