【 摘 要 】

Effect of tungsten (W) concentration on Acetobacter xylinum growth was studied. In the experimental procedure, concentration of W in the bacterial growth medium containing pineapple peels waste was varied from 0.5 to 50 ppm. To confirm the influence of W, the bacterial incubation process was carried out for 72 hours. Spectrophotometer analysis showed that the growth rate of Acetobacter xylinum decreased with increasing concentration of W. The result from fourier transform infra red analysis showed a slightly change on the absorption peak intensities and informing the interaction of W ion and bacteria cell. The result confirmed that Acetobacter xylinum was able to uptake W concentration up to 15 ppm, indicating that Acetobacter xylinum might act as a promising agent for eco-friendly recycling system.
