Antibacterial activity of the aerial extracts from Xanthium brasilicum prepared in methanol, diethyl ether, petroleum benzene and an equal mixture of the three solvents were studied against bacterial laboratory standards and clinical isolates using the disk diffusion method. The best antibacterial results were obtained when methanol or the solvent mixture was used. The crude extract with the hi...

background aeromonas hydrophila cause one of the most important diseases in fishes and lead to economic losses, and may be contaminated human beings. objectives the current research aimed to investigate the anti-bacterial activity shown by the extracts prepared from different parts of olea europea, myrtus communis, thymus vulgaris, rosmarinuis officinalis, and achillea falcata that grow in syri...

Sponges, which constitute the phylum Porifera, are the most primitive of the multicellular animals, among all marine organisms screened. Marine sponges produce the largest number of structurally diversified natural products. In this study we investigated in vitro antimicrobial activity of Ircinia mutans collected from the Kish Island in the Persian Gulf against strains of bacteria Escherichia c...

objective: the aim of present study was cloning and expression of phic31 integrase cdna in a bacterial expression vector. thus, an intra molecular assay vector was applied to show in vitro activity of recombinant protein. materials and methods: in this experimental study, phic31 cdna was subcloned into a prokaryotic expression vector and transformed into e.coli bl21 (de3). recombinant phic31 in...

The condensation reaction of 5-(4-aminophenyl)-4-phenyl-1,2,4-triazole-3-thione with salicylaldehyde, 4-hydroxybenzaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4-nitrobenzaldehyde and 4-methoxybenzaldehyde in methanol results in series of new Schiff bases. The structure of Schiff bases were confirmed by 1H NMR, 13C NMR, IR and mass spectro...

Bacterial cellulose- Curcuma Longa Linn from acetobacter xylinum has been produced. The aim of research: To isolate Cellulose-Curcuma Acetobacter and to improve activity catalitic bacterial cellulose. Morphology properties was carried out on sample cellulose extract. This characteristic test by Scanning Electron Microscope (SEM).
