In this study, nanoemulsions of essential oil from Ocimum gratissimum (Linn) (EO) were produced using low and high energy techniques using cashew gum (CG) as a co-surfactant. The main constituents of the EO were determined by Gas Chromatography coupled with Mass Spectrometry (GC?MS), and their presence in the EO and in the formulations verified by Fourier Transform Infrared Spectroscopy (FTIR) and UV?visible spectrophotometry was observed the encapsulation efficiency (EE%), with colloidal stability. Nuclear magnetic resonance (NMR) was used to study cashew gum. Dynamic light scattering analysis (DLS) determined the nanoemulsion Z means, polydispersity index and the Zeta potential value, nanoparticle tracking analysis (NTA) were determined. The nanostructured EO showed better antibacterial action against the pathogenic gastroenteritis species Staphylococcus aureus, Escherichia coli and Salmonella enterica when compared to free EO. Atomic Force Microscopy (AFM) was used for morphological analysis of the nanoparticle and study of the action of the nanoemulsion through images of the cellular morphology of S. enterica. The antioxidant activity was evaluated against the ABTS radical (2,2?-azino-bis diazonium salt (3-ethylbenzothiazoline-6-sulfonic acid)). The encapsulation of EO in a nanostructured system improved its antibacterial and antioxidant activity, the low energy synthesis showed greater storage stability, remaining stable for 37?days. |

Conteúdo: |
Classical biological control involves the introduction, establishment and colonization of natural enemies to reduce damages caused by pest organisms. It is commonly conducted when effective, pre-established biocontrol agents are not available or when the summed effects of available agents is not enough to prevent significant pest damage. Most countries with intensive biocontrol activities regulate the importation and exportation of natural enemies to reduce the chances of unintentional introductions of undesirable organisms in those processes. Regulations are expected to fulfill its main goal, but should not be excessively restrictive to hinder biocontrol activities. FAO has dedicated itself to contribute to the establishment of guidelines that member countries could adopt or base themselves when defining their national regulations. Brazil is also developing its own protocol, which at the same time has been discussed with neighboring countries in the South for a harmonization of the rules. Regionally accepted protocols should always be considered, because political boundaries, and a natural enemy released in a country may easily spread into neighboring countries which share given ecosystems. |
