| Research Abstract |
The antibacterial activity of immobilized photo-catalytic in alginate gel was investigated under visible light illumination. TiO_2 or S-TiO_2 in the alginate gel did not reveal visible light-induced antibacterial activity. The antibacterial activity increased when copper was added to the S-TiO_2 as supplements. The immobilized S-TiO_2+Cu 7%(w/w) in alginate gel beads were showed high antibacterial activity by photo-catalytic activity. This result showed alginate gel beads were usefulness as the photo-catalytic carrier. In addition, when the immobilized S-TiO_2+Cu in alginate gel beads applied to seed sterilization, it was possible to sterilize without affecting the germination and the sprout length.
