The effect of titanium dioxide to the bacterial growth on lysogeny broth agar

Abstract

In this paper, the effect of Titanium dioxide powder to the bacterial growth on Lysogeny broth (LB) were investigated. LB agar used as a nutrient media to grow bacteria from drain water mixed with different weight of TiO 2 The image of the cultured plate was captured using webcam. Then the size of bacterial colonies was measured by Microsoft Visual Basic software. The result shows that the Titanium dioxide powder are able to decrease the growth of bacterial colonies in the drain water sample. This finding suggests that the Titanium dioxide have a potential to be used as purification agent in water treatment process. © 2011 Springer-Verlag.
