The research studied the antibacterial properties of five essential oils (EO) on Escherichia coli O157:H7. The results show that oregano and thyme EO have significant in vitro colicidal and colistatic properties and are exhibited in a broad temperature range. The effects were greatly improved by the addition of agar as stabilizer. Bay and clove bud EO are shown less active in reducing the numbe...

Three 1-(2-hydroxyethyl)-3-alkylimidazolium chloride room temperature ionic liquids (ILs) [2OHimC(n)][Cl]; (n=0, 1, 4) have been synthesized from the appropriate imidazole precursors and characterized by IR and NMR spectroscopies and elemental analysis. Their anti-microbial activities were investigated using the well-diffusion method. The viabilities of Escherichia coli, Aeromonas hydrophila, L...

The present study was carried out to evaluate the in vitro antimicrobial and antioxidant activity of Emblica officinalis juice powder. The antimicrobial activity was assessed against gram positive and gram negative bacteria namely E.coli, Pseudomonas fluoresces, Bacillus subtilis, S.aureus, and fungi namely Aspergillus niger, Penicillium chrysogenum, Alternaria alternata, and Fusarium spp by ag...

Formation of biofilm in pathogenic bacteria defends them from antibiotics and the immune system of a host's life. Hence, investigation of the molecular mechanisms of biofilm formation and search for new substances counteracting this formation are becoming an attractive research area. In the course of our search for new inhibitors of biofilm formation in Mycobacterium species, we rediscovered a ...
