Application of zero valent nano iron on bacterial growth

In This thesis, the aim of this study was to determine the positive and negative effects of the development of nanoparticle zero-valent iron (Fe) on bacteria. Zerovalued nano-iron particles were synthesized by reduction method with calm average distribution around 45 nm to provide bacterial permeability. Yoghurt bacteria Lactobacillus Bulgaricus and Streptococcus thermophilus isolates were grown in solid medium in order to calculate the effect rate of nanoparticles on the development. As a result of the study, it was observed that the maximum value was reached at the end of the incubation period and the growth rate of the control group samples. It is seen that 5 ppm amount is the fastest development among the other groups in which nanoparticle is added. However, it was determined that the media ratio above 5ppm prevents bacterial growth.
