Evaluation of anbacterial activity of mixture containing turmeric oil against bactetial

Abstract

Turmeric oil has been known as possessing anlioxidant and antimicroorganism activities, especially growth inhibition of fresh fruit spoiling microorganisms. Turmeric oil was used in traditional medicine for decades in Asian counfries for disease treatment. Chitosan is a natural carbohydrate polymer, can be produced by deacetylation of chitjn, with various features as biological compatible, biological degradation, adherent membrane, antirmcroorganism and harmless, so is used for application investigation in biopharmacology and function food. Chitosan were processed into nanoparticles and is used as a vehicle for drug delivery and gene transformation. For making natural product in posthaverst fruit preservation as an alternative for commonly used chemicals, antibacterial activity of nanochitosan (NCS), NCS with turmeric oil (TDN) and mixture of NCS, TON and siver nanopartjcles was determined. Recieved results showed that NCS, NCS-TDN and NCS-TDN-NB have not only growth inhibition activity against Bacillus cereus, and Lislonella damsela, but also bactericidal activity. Combination of NCS, TDN and NB significantly enhances their antibactenal activity.
