In this study, the antimicrobial activity of eight natural extracts (Citrus bergamia, Ocimum basilicum, Melissa officinalis, Eucaliptus, Pelargonium graveolens, Argania spinosa, Ricinus communis) over some nosocomial bacterial strains isolated from hospital units (Staphylococcus aureus M215, Escherichia coli M49 and Streptococcus pyogenes M372) has been studied using the diffusion method. The highest antibacterial effect was exhibited by the basil (Ocimum basilicum) and eucalyptus (Eucaliptus) oil (0.7 mm and 1.3 ...

This work has pursued the accumulation process of aromatic compounds such as esters in three varieties of Romanian native wines from Apoldu de Jos, namely Feteasc? regal?, Feteasc? alb? and Iordana, obtained by fermenting them in a microvinification system, in a bioreactor equipped with temperature sensors for pH and CO2. The pectolytic enzymes Enozym flavors (3g/100 kg) and selected Vinartis ferm yeasts as Saccharomyces cerevisiae strain were used for the alcoholic fermentation. To identify and quantify the ester...
