| description | The objective of this study was to investigate the antibacterial and antioxidant effect of Greek oregano and rosemary by-products from essential oil distillation on pathogenic and spoilage bacteria. The antibacterial effect of raw material of oregano and rosemary before distillation and post distillation, the dried residues, was tested against the following bacteria: <i>Escherichia coli</i>, <i>Salmonella enterica</i> subsp. <i>enterica</i> ser. Typhimurium, <i>Listeria monocytogenes</i>, <i>Staphylococcus aureus</i>, <i>Bacillus subtilis</i>, <i>Bacillus licheniformis</i>, and <i>Bacillus cereus</i> strains. Results showed that rosemary distillation by-products were able to inhibit the growth of all <i>Bacillus</i> (<i>B. subtilis</i>, <i>B. licheniformis</i>, <i>B. cereus</i>) strains and <i>L. monocytogenes</i> while oregano affected the growth of <i>L. monocytogenes</i> and <i>S. aureus</i>, even at the minimum concentration. However, it affected <i>B. cereus</i>, at the maximum concentration. The total phenolic content in oregano/rosemary raw material and their by-products was approximately similar; however, antioxidant activity was reduced in oregano solid residue, whereas it was surprisingly increased in the rosemary by-products after distillation. These results suggest the potential use of oregano and rosemary distillation by-products as antimicrobial and bioactive agents. |
