Abstract:
7,10-Dihydroxy-8(E)-octadecenoic acid (DOD), one of hydroxy fatty acids, was successfully produced from oleic acid and natural vegetable oils containing oleic acid by a bacterial strain Pseudomonas aeruginosa (PR3). However, biological properties of DOD remained unknown so far. In this study, as a trial to determine the biological properties of DOD molecule, antibacterial activities of DOD against plant pathogenic bacteria were determined qualitatively and quantitatively. DOD presented strong antibacterial activities against all the bacterial strains tested with MIC value being in the range of 125-1000μg/ml and there was no sensitivity preference detected between Gram-positive and Gram-negative strains.

Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
