In the present study the ethanol extract of the aerial part of Andrographis paniculata was prepared and evaluated for antimicrobial activity against eleven bacterial strains by determining minimum inhibitory concentration and zone of inhibition. Minimum inhibitory concentration values were compared with control and zone of inhibition values were compared with standard ciprofloxacin in concentra...

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...

throughout the present study, some bacillus spp. were isolated from soil, and the effectiveness of the medicinal plant cuminum cyminum l.’s essential oil extracts were tested against the isolated bacteria. the bacillus spp.were identified through 16s rdna sequence analysis and the antibacterial activity of various organic solvent extracts as well as the essential oils of c. cyminum l. determine...

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...
