Outline of Final Research Achievements

To analyze disinfestation mechanism against soil living pests by anaerobic soil disinfestation (ASD) method using various organic substances such as ethanol, we have continuously assessed various soil characters such as oxidation-reduction potential, pH, metabolism of additive carbon sources, concentration of metal ions and population dynamics of soil microorganisms during the anaerobic soil disinfestation treatment. Therefore, anaerobic condition was quickly induced by soil microorganisms during their oxidative metabolism of additive carbon sources. Thereafter antibiotic materials such as acetic acid and metal ions which can kill or decrease numbers of the soil living pests were produced and accumulated in soil along with rapid multiplication of several kinds of anaerobic soil bacteria. It suggests that soil microorganisms such as anaerobic bacteria would play important role for ASD.
