Phytochemical and Antimicrobial Properties of Oil Extracts from the Seeds of Ricinodendron heudelotii

Conclusion: Amongst the bacteria used, highest MIC of 150 mg mL–1 was recorded for Staphylococcus aureus, while lowest MIC of 50 mg mL–1 was observed in E. coli. Highest activity was observed against the fungus, Candida albicans with MIC of 25 mg mL–1.

Publication date: Available online 20 April 2018 Source:Journal of Pharmaceutical Analysis Author(s): Hina Singh, Juan Du, Priyanka Singh, Tae Hoo Yi Silver nanoparticles (AgNPs) are known to have bacteriostatic and bactericidal effects. The present study highlights the extracellular synthesis of AgNPs and its antibacterial properties. The AgNPs are synthesized using Pseudomonas sp. THG-LS1.4, the strain has been isolated from soil. The AgNPs were characterized by field emission-transmission electron microscopy (FE-TEM), X-ray diffraction (XRD), fourier transform-infrared spectroscopy (FT-IR), and particle size distributi...

Duquesne The aim of this study was to examine the influence of accelerated UV-aging on the activity against chosen microorganisms and the mechanical properties of poly-lactic acid (PLA) films enhanced with ZnO nanoparticles. The pure PLA films and tri-layered PLAZnO1%/PLA/PLAZnO1% films of 150 µm thickness were extruded. The samples were treated with UV-A and Q-SUN irradiation. After irradiation the antimicrobial activity and mechanical properties of the films were analyzed. The results of the study demonstrated that PLA films did not inhibit the growth of Staphylococcus aureus, Bacillus cereus, Escherichia coli,...

Abstract ObjectivePathogenic contamination of cosmetics intended to be applied on or around the eye area, including make‐up removers, may lead to severe eye infections. To assess the efficacy of antimicrobial preservatives in these products, we investigated the survival and detection of Bacillus cereus F 4227A spiked into make‐up removers, alone and in the presence of other relevant micro‐organisms. MethodsFour brands of make‐up removers, A, B, C and D, were challenged three times (day 0, day 7 and day 14) using B. cereus, in pure and mixed cultures, at a final concentration of 5 log CFU per mL of Bacillus cereus o...
