Some new b-lactams bearing biologically important morpholine ring have been synthesized by acylation of amino b-lactams in the presence of morpholine-4-carbonyl chloride. These novel β-lactams were prepared under mild reaction conditions without any solvent in short reaction times. Their biological activities have been examined against microbial agents such as Staphylococcus aureus (S. aureus),...

The present study investigated the effect of sumac (SWE) and rosemary water extracts (RWE) on microbial growth in ground beef meat during refrigerated storage. The meat samples were explored for changes in TVC, E. coli (0157:H7) and S. aureus populations. Antimicrobial effectiveness of extracts was more pronounced against gram-positive strain compared with gram-negative strain...

Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs) biosynthesized greenly using exopolysaccharides (EPS) and Culture Free Supernatant (CFS) of Wesiella confusa against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticles were characterized by UV-visible spectra, Fourier Transfor...

gum of butea monosperma is used to treat microbial and fungal infections in folk medicine. to validate this use, the in- vitro antimicrobial activity of petroleum ether and alcoholic extract of butea monosperma gum was evaluated against various microbial strains such as staphylococcus aureus, bacillus subtilis, bacillus cereus, salmonella typhimurium , pseudomonas aeuriogenosa, escherichia coli...

The antibacterial activity of a series of ionic liquids containing short-chained 1-alkyl-3-methylimidazolium cations ([Cnmim+]; n = 2, 4, 6 and 8) and bis (trifluoromethylsulfonyl) imide anion ([Tf2N]) against E. coli and B. subtilis was measured, for the first time. All ILs used in this work were synthesized and analyzed by Fourier transform i...

BACKGROUND In Europe, Acacia and Eucalyptus, originate large amounts of biomass, due to their need by industries and other biological control, that can be used to extract antimicrobial substances. MATERIALS AND METHODS Foliar aqueous, ethanolic and methanolic extracts of Acacia baileyana (Cootamundra wattle), Acacia dealbata (silver wattle), Acacia melanoxylon (black wattle) and Eucalyptus ni...
