Abstract
Latterly, natural products have been used as antibiotics and have proven effective against a large number of
microorganisms. The present study included the measurement of antibacterial activities of pomegranate juice
or molasses, tamarind molasses, garlic oil with thyme and with chili pepper on the five selected bacteria (2
Gr+ and 3 Gr-) by disk and agar well diffusion assays on the Muller Hinton Agar (MHA) and Blood Agar
(BA). Pomegranate and tamarind molasses exhibited a broad spectrum of anti-bacterial activity inhibiting
both the groups of bacteria. Pomegranate and tamarind molasses has shown highest antimicrobial activity
compared to garlic oil with herbs. Inter- selected of bacterial cultures, the highest antibacterial effect of
pomegranate and tamarind molasses by using disk diffusion was recorded against E. coli, Staphylococcus
aureus, Streptococcus mutans and Pseudomonas aeruginosa (20,18,20,12 mm) (20,20,20,17 mm)
respectively while, when used agar well diffusion assay to tested antibacterial activities of pomegranate and
tamarind molasses the result show rather increased inhibition zone of selected bacteria but, bacterial culture
of Klepsiella pneumonia recorded resistance against food additives which can used in this study.
