S. griseus isolated from soil samples was screened for production of streptomycin by plate assay. Identification of streptomycin antibiotic was done by paper chromatography using selected strains of bacteria by measuring the zone of inhibition. Among all the bacterial strains studied, the highest zone of inhibition was measured against E. coli whereas lowest was measured against S. aureus after...

The juices of leaves and stem of Mentha piperita (peppermint), skin and seeds of Pisum sativum (garden pea), skin and pulp of Momordica charantia (bitter melon) were screened for antibacterial activities against 56 isolates belonging to 11 different species of Gram-negative bacilli: Escherichia coli (19), Klebsiella pneumoniae (11), Pseudomonas aeruginosa (9), Salmonella typhi (3), Salmonella p...

The aim of present work is to evaluate the antimicrobial activity of clove and ginger powder extracts on Streptococcus Mutans. An in-vitro study was conducted to assess effectiveness of 5%, 10%, and 50% clove and ginger powder extracts on Streptococcus mutans. The ditch plate method was used to test the antimicrobial activity. Ditches were prepared on blood agar plates with the help of punch ha...

Molluscs are highly delicious seafood and they are also very good source for biomedically imported products. Among the molluscs some have pronounced pharmacological activities or other properties which are useful in the biomedical area. In the present study antimicrobial activity of gill extraction of Perna viridis was investigated. In antibacterial activity the maximum zone of inhibition (19 m...

Seventy isolates belonging to 3 different species of gram-negative bacilli: E.coli(30), K.pneurnoniae(05), and P.aeruginosa(05), and I specie of gram-positive cocci: S.aureus(30), were used for screening of antibacterial activity of aqueous infusion, decoction and essential oil of cinnamon by standard disc diffusion method. The oil of cinnamon exhibited highest antibacterial activity against S....

this paper reports on preparation of polyamide membrane with addition of silver nanoparticles (agnps). agnps act as antibacterial agents that are less susceptible to membrane’s biofouling by interfacial polymerization (ip) method. agnps was synthesized via green route which has been reported previously. attenuated total reflectance-fourier transform infrared spectroscopy (atr-ftir), field emiss...

conclusions the results of the present study indicate that brazilian propolis demonstrated in vitro anti-microbial efficacy against s. mutans and c. albicans. results the antimicrobial efficacy of hexidine against s. mutans and e. coli was higher compared to that of c. albicans. the brazilian propolis (p) mr showed antimicrobial action against s. mutans and c. albicans. the antimicrobial effica...

the genus rhodococcus is gram positive bacterium which was classified into the family of nocardiaceae. the organism can be isolates from different sources, with capability to degrade diverse types of pollutant. nowadays, scientists reported a few secondary metabolites which are produced by rhodococci. hence, the present study tried to isolate rhodococci from different soil samples with the capa...

purpose: in this study, we have focused on antibacterial effect of newly synthesized thiazole, imidazole and tetrahydropyrimidine derivatives in iran on listeria monocytogenes. materials and methods: for evaluation of antibacterial effect, the disk diffusion method was applied to measure the growth inhibition zone diameter and broth micro dilution was performed to determine the minimum inhibito...
