The chemical composition of essential oils isolated from the leaves of Cosmos bipinnatus and its antibacterial activity were analyzed by GC-MS and microbroth dilution assay respectively. The essential oil extracted from this plant was predominantly composed of monoterpenes (69.62%) and sesquiterpenes (22.73%). The antibacterial assay showed that the oil had significant inhibitory effects agains...

a wide range of medicinal plant parts that possess varied medicinal properties are used for extracts as raw drugs. in this study, the ethanolic extract obtained from aerial parts of fennel (foeniculum vulgare mill.) seedlings was evaluated in vitro to examine their antimicrobial activity against four gram-negative and three gram-positive bacteria and two fungi. aerial parts of one-month-old see...

We report in this work the antibacterial evaluation of 12 lipophilic fluoroquinolone derivatives containing diaminoalkyl side chains at C-7 position. The compounds were investigated against 15 bacterial strains including gram-negative and gram-positive species of clinical and microbiological importance. Three compounds (5, 10 and 11) were as active as or more efficient than gatifloxacin against...

In the course of a study of the microbial flora of fresh pork sausage (Sulzbacher and McLean, 1951) a gram positive rod associated with sausage flavor deterioration was isolated repeatedly. Although this organism tentatively was identified as belonging to the genus Microbacterium, it differs sufficiently from the described species of that genus to justify the publication of a complete descripti...
