Abstract

Foot and mouth disease (FMD) is highly infectious disease of cloven-hoofed animals, particularly problematic in cattle, sheep, pigs and goats for economic reasons. Last FMD outbreak in February, 2017 caused tremendous social and economical impacts. The Korean FMD policy aims to vaccinate intact animals and euthanize and bury infected animals to prevent the disease spread. However, there was a problem that the buried livestock did not decompose after several years. Therefore, the study was purposed to investigate the effect of Corynebacterium glutamicum and Bacillus licheniformis on the degradation of buried cow carcasses and on the soil condition; such as temperature, decomposition course of carcasses, composition of amino acids in the soil around carcasses, and plant root elongation to measure soil conditions. As a result, the composition of amino acids in the soil treated with C. glutamicum and B. licheniformis was generally higher than those in the untreated soil. Plant roots in soil treated with C. glutamicum and B. licheniformis grew longer than in non-treated soil. The results suggested that the toxic effect on a grave land buried with FMD infected livestock is reduced when treated with C. glutamicum and B. licheniformis in regard of odor reduction, promoted decaying process, and soil fertilization.
