Comparison on Lysobacter enzymogenes wt strain C3 and avirulent mutant strain DCA on MTT-formazan production during interactions with Cryphonectria parasitica. Treatments consisted of bacterial inocula densities of 2 × 10⁸ cfu/ml. Treatment tests consisted of supplementation with and without antibiotics chloramphenicol (3.6 mg/ml) and gentamycin (3.6 mg/ml). Results were normalized and presented as percentages of fungal cell controls that received no bacterial treatment, but received antibiotic supplementation. Each value represents the mean of 4 replicates. Like letters represent no significant difference at each time point according to student Student–Newman–Keuls test (P = 0.05)
