Analysis of antimicrobial activity by defense fluid of Odontotermes Sarawakensis Holmgren on selected soil microbes

This study was about using the agar disk diffusion assay to test the antimicrobial activity of methanol extract of defense fluid of termite soldier of Odontotermes Sarawakensis Holmgren. The antimicrobial test was done on two different types of mound soil microbes, Pkh.Umk_01 as Gram positive and Pl...

The termite soldiers were collected and its defense fluid was extracted with methanol that prepared at different concentration. Distilled water was served as negative control while the 6 nun of 10 mg/ml Gentamicin disk was served as positive control. Six crude extract concentration was used to determine the Minimum Inhibitory Concentration (MIC), which 10.0 mg/ml, 4.0 mg/ml, 2.0 mg/ml, 1.0 mg/ml, 0.5 mg/ml, and 0.1 mg/ml.

The antimicrobial activity were analyzed by using one way analysis of variance (ANOVA) with Independent t-test to perform a confident level of 95%. From ANOVA test, the results showed that not all concentration of defense fluid were significant as P<0.05 after performed the multiple comparison. There were only at concentrations of 10.0 mg/ml and 0.1 mg/ml that showed the significance as P<0.05.

The control of 10 mg/ml of Gentamicin and 10 mg/ml of crude extract were significance as P<0.05 at Pkh.Umk_02 (Gram negative) and B. subtilis which it showed the differences in performance of antimicrobial activity in inhibiting microbes growth.
