Extract A and extract B were tested for their ability to inhibit growth of E. carotovora subsp. carotovora, as a plant pathogen and Gram negative bacteria, and compared to its ability to inhibit B. subtilis representing Gram positive bacteria. As shown in Table 1 and Fig. 2, extract A and B could inhibit growth of E. carotovora subsp. carotovora. Extract A gave significantly higher inhibition zones (p < 0.05) than extract B and Amoxicillin, to both bioassays against E. carotovora subsp. carotovora and B subtilis. Extract B gave significantly higher inhibition zones toward B. subtilis (p < 0.05), than toward E. carotovora subsp. carotovora, but had the same inhibition zone as the positive control Amoxicillin toward B. subtilis. No inhibition zones were detected in the negative controls.
