Antimicrobial Activity of Bacillus sp. Lts 40 against Ralstonia solanacearum, Pseudomonas syringae pv. glycines, and Pseudomonas fluorescens.
Abstract
The using of chemical substance as biocontrol could leave the residue which acumulated on environment. Therefore, it is necessary to have more safety and non residual substances. Determination of antimicrobial activity of Bacillus sp. Lts 40 isolated from shirmp pond was conducted in vitro experiments. This isolate was assayed their inhibition activity to the growth of six isolates (Escherichia coli, Staphylococcus aureus, Pseudomonas fluorescens A, Pseudomonas fluorescens B, Ralstonia solanacearum, and Pseudomonas syringae pv. glycines) of plant pathogenic bacteria using spread plate method. The results showed that the isolate was able to inhibit the growth of all indicator bacteria. The higher inhibiting activity was found on Ralstonia solanacearum.
