This paper is to study the characteristics of super activated material series(SAMs) powders and their influence on the lethality and multiplication of microbes. SAMs are composed of lime powder up to 95.5%, most of which are minerals of 400 mesh. In them, CaO is 774.16 ppm, P2O5 374.25 ppm, SiO2 62.37% while Pb, Cd, Hg and As were not found. According to the observation with the scanning electron microscope(SEM), they had a sheet structure without air pores. They showed no smell, flavor and elution of color. Average radiation rate of far-infrared rays was 0.93 μm, and average radiation energy of far-infrared was 3.74×102 W/m2/μm. When A. niger was cultured on the SAMs culture medium, it showed 100% sterilizing power in a week and on. E. coli showed 86.1% reduction on the SAMs medium; P. aeruginous 82.7%. In the water tank medium to which SAMs were added by 5 g/L, the surviving population of Cochlodinium polykrikoides decreased from initial 53% to 20%; In the medium by 10 g/L, it reduced from 60% to 10%. In the medium for A. niger to which 0.05-0.3% SAMs were added, its pH was from 6.6 to 4.4 after 24-48 hours, showing that it became lower according to the concentration of SAMs. The multiplication of cells increased according to the concentration of SAMs. pH of L. acidophilus culture medium added with 0.25-0.3% SAMs decreased from initial 6.6 to 5-4.9 after cultivation of 24-48 hours. But, in the medium of 0-0.1% SAMs, pH increased after 24 hours. The number of cells increased according to the concentration of SAMs. In the 0.5% SAMs medium, pH of Agrobacterium sp. changed from initial 6.09 to 6.55. The measurement of cell mass O.D. increased to 18.65 at 0.5% SAMs medium when compared with that at 0% medium. When the concentration of SAMs was 0%, the dry cell weight was 2.55 g/L. But when the concentration was 0.5%, it increased to 6.80 g/L. The production of polymer curdian was not influenced by SAMs concentration.
