Table 3. Antibacterial activities (inhibitory zone assay) of ex-LMSI, ex-LMSII, and ex-LMSIII (1mg/mL) isolated from C. unicolor submerged cultures.
Diameters of the inhibition zones (mm) | |||
---|---|---|---|
E. coli | S. aureus | B. subtilis | |
ex-LMS I | 1.68 ± 0.16ab | 2.38 ± 0.14a | 1.69 ± 0.11a |
ex-LMS II | 1.96 ± 0.12a | 3.21 ± 0.23b | 2.76 ± 0.19b |
ex-LMS III | 1.55 ± 0.14b | 2.36 ± 0.30a | 2.76 ± 0.19b |
physiological saline | -a | -a | -a |
penicillin sodiumb | 2.86 ± 0.17c | 3.08 ± 0.26b | 3.01 ± 0.16b |
All results are expressed as mean ± SD from three experiments (n = 3). Values with different letters within the columns are significantly different (p ≤ 0.05).
aNot detected.
bThe concentration of penicillin sodium was 0.5 mg/well for the Gram-negative microorganisms and 0.25 mg/well for the Gram-positive bacteria.
