Observation of Effective Micro-Organisms Attached on Porous Ceramics
Effective micro-organisms (EM) increase the natural resistance of soil and plants, and it considerably improves the quality and fertility of soil as well as the growth and quality of crops. In this study, we prepared two types of porous ceramics with high and low porosity, and observed the attaching behavior of micro-organisms to the surface of ceramics. In the case of highly porous ceramics with large pore (80% in porosity), many of micro-organisms were observed in the pores of interior as well as on the ceramic surfaces. However, most of micro-organisms attached on the surface of the low porous ceramics with small pore (45% porosity), and only a few micro-organisms observed in pore inside.
