Antibacterial and tick repellent properties of microcapsules containing plai oil

Abstract

The purposes of this experimental research were 1) to study the size and shape of microcapsule containing plai oil 2) to test the antibacterial ability of active microcapsule and 3) to explore microcapsule containing plai oil in order to get rid of ticks.The results of this study showed that the microcapsules were round-shaped with core-shell morphology. The antibacterial efficiency of microcapsules was determined and the result showed that the microcapsules containing plai oil have excellent antibacterial activity against Escherichia coli and Bacillus cereus. The efficacy of plai oil filled microcapsules against adult dog ticks was determined and found that microcapsules of plai oil can get rid of tick. However, the tick repellency depended on amount of plai oil released from microcapsule.
