ACTIVITE ANTIBACTERIENNE DE L’HUILE DE CADE SUR QUELQUES SOUCHES DE STAPHYLOCOQUES: APPLICATION SUR DES EAUX USEES TRAITEES PAR LAGUNAGE AERE

Abstract

Cade oil is obtained after pyrogenation distillation of Juniperus oxycedrus. It is traditionally used to perfume drinking water in southern Algeria. It usually coats the bottom of water jars, jugs and the inside of guerba, without understanding the reason for this traditional ritual. The present study aims to explore the antibacterial property of this oil on treated wastewater from the aerated lagoon treatment plant in the city of Ouargla (Algeria). In view of the results, it appears that cade oil has a notable bactericidal power on the strains of the staphylococcus genus tested (zones of inhibition ranging from 20.84 mm to 32.51 mm). The addition of this oil to a sample of wastewater treated by aerated lagooning causes a 97% decrease in the level of staphylococcal strains after 24 hours.
