Objective (s): The green synthesis of copper nanoparticles using metabolites of microorganisms has gained much interest in recent years. In this work, it was studied optimization of copper nanoparticles synthesis using E. coli and its antifungal activity.Materials and Methods: The copper nanoparticles were synthesized by Escherichia coli. Effect of copper nitrate concentration and temperature w...

BACKGROUND Essential oil components eugenol and carvacrol (ranging between 100 and 200 ppm for carvacrol and between 250 and 750 ppm for eugenol) were tested for antifungal activity against foodborne pathogenic fungal species Aspergillus carbonarius A1102 and Penicillium roqueforti PTFKK29 in in vitro and in situ conditions. MATERIALS AND METHODS In vitro antifungal activity of eugenol and ca...

We read with interest the article from Shanin et al. about the Fungal Infection Risk Evaluation (FIRE) study [1] aiming to ‘describe the incidence of IFD in UK critical care units and to develop and validate a clinical risk prediction tool to identify non-neutropenic, critically ill adult patients at risk of IFD’. The investigators should be congratulated for the way they collected a huge amoun...

Oxidative treatment is one of the strategies for preventing Penicillium contamination in crops/foods. The antifungal efficacy of hydrogen peroxide (H2O2; oxidant) was investigated in Penicillium strains by using kojic acid (KA) as a chemosensitizing agent, which can enhance the susceptibility of pathogens to antifungal agents. Co-application of KA with H2O2 (chemosensitization) resulted in the ...

The bacteria which are members of the genus Bacillus are known to produce a wide variety of antimicrobial substances and bacteriocins. The main objective of this study was to investigate the effect of these bacteriocins on eukaryotic cells such as fungi, yeast and plant seeds. Several strains were screened for antifungal activities and identified by the means of polymerase chain reacti...

conclusions the results of this study show that the beneficial effect of lactobacillus casei is related to its metabolites. a formulated gel shows a significant antidermatophytosis activity compared to clotrimazole. results the results showed the same effect of the probiotic extract against 4 pathogens; however, the greatest average zone of inhibition was measured 34 mm against t. rubrum. the m...
