An Investigation About Antimicrobial Activity of Black Crocus (Stenbergia Fischeriana)

Abstract

This study investigated the antimicrobial activity of black crocus (Stenbergia fischeriana), a poisonous herb, on some Gram (+) and Gram (-) microorganisms. Extracts of black crocus were prepared in acetone and tested against Corynebacterium. xerosis UC 9165, Micrococcus luteus A 2971, Mycobacterium smegmatis CCM 2067, Klebsiella pneumonia FML 5, Bacillus megaterium NRS, Pseudomonas aeruginosa ATCC 27853, Bacillus megaterium. DSM 32 Enterococcus faecalis ATCC 15753 and Staphylococcus aureus ATCC 25923 with the disk diffusion method Black crocus had inhibitory activity on Staphylococcus aureus ATCC 25923, Mycobacterium smegmatis CCM 2067, Enterococcus faecalis ATCC 15753 and Klebsiella pneumonia FML 5 but has no inhibitory activity against other bacteria strains.
