Research Abstract	In this study, mechanical characteristics of improved soil using bacteria were examined in order to develop the aseismic reinforcement of existing houses. A series of tri-axial compression tests was carried out under several conditions. Influences of a kind of bacterium and a kind of soil on the improved soil behavior were also examined. The results revealed that the kind of bacterium affected to a reaction rate and the kind of soil did not affect to the shear strength of improved soil. Comparing the no-improved soil, the improved soil has higher deformation resistance.
