Effect of Corynebacterium glutamicum on Livestock Material Burial Treatment

摘要

In recent years, foot-and-mouth disease has occurred in all parts of the world. The animals with the disease are buried in the ground; therefore, their concentration could affect ground or groundwater. Moreover, the complete degradation of carcasses is not a certainty, and their disposal is important to prevent humans, livestock, and the environment from being affected with the disease. The treatment of Corynebacterium glutamicum is a feasible method to reduce the risk of carcass decomposition affecting humans or the environment. Therefore, this study aimed to investigate the effect of C. glutamicum on the soil environment with a carcass. The composition of amino acids in the soil treated with C. glutamicum was generally higher than those in the untreated soil. Moreover, the plant root in the soil samples treated with C. glutamicum had 84.0% amino acids relative to the standard value and was similar to that of the control. The results of this study suggest the possibility to reduce the toxicity of a grave land containing animals with this disease.
