10.22376/ijpbs.2019.10.1.p1-12 Volume 2 Issue 4 2011 (October - December) Ethanol, methanol and aqueous extracts of lessThan i greaterThan Foeniculum vulgare lessThan /i greaterThan Mill. seeds were investigated for lessThan i greaterThan in vitro lessThan /i greaterThan antibacterial screening by Agar well and Disc diffusion method against lessThan i greaterThan Escherichia coli lessThan /i greaterThan , lessThan i greaterThan Klebsiella pneumoniae lessThan /i greaterThan , lessThan i greaterThan Proteus vulgaris lessThan /i greaterThan , lessThan i greaterThan Enterobacter lessThan /i greaterThan lessThan i greaterThan aerogeus, Salmonella typhi, Bacillus cereus lessThan /i greaterThan and lessThan i greaterThan Staphylococcus aureus. In Both lessThan /i greaterThan agarwell and disc diffusion methods, the highest inhibition zone was found in aqueous extracts. It showed greater activity against the maximum tested bacteria followed by ethanol and methanol extract. lessThan i greaterThan lessThan /i greaterThan The preliminary results of this study lessThan i greaterThan lessThan /i greaterThan indicate that the aqueous seed extracts lessThan i greaterThan lessThan /i greaterThan have potentials for antibacterial activity.  Manonmani , And V.
