The inhibition effect of Nigella sativa oil extract on the growth of some gram positive and negative bacteria
Journal Title: Journal of Research in Ecology - Year 2018, Vol 6, Issue 1
Abstract
In this study, the inhibition activity of Nigella Sativa oil extracted Clevenger apparatus by the process the hydro distillation was examined against seven species of pathogenic bacteria Staphylococcus aureus, Micrococcus sp, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Serratia marcescens, Salmonella sp. Agar well diffusion method was used to estimate the inhibiting activity of the extracted oil. The results of this study revealed that the oil extracts of Nigella Sativa is good at inhibiting Grams negative and Gram positive bacteria. The highest inhibition percentage were at 50% concentrate of the oils extracted and showed 33.80, 33.94, 26.61, 25.32, 32.23, 23.32 and 32.37 % against Staphylococcus aureus, Micrococcus sp, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Serratia marcescens, Salmonella sp
