Abstract

The current study explored the possibility to attach bacteria and yeasts to micro-silica particles. The aim of the study was to determine possible differences in the speed of rates of turbidity (or speed of adherence) between suspensions of bacteria and yeasts with and without silica micro-particles. Some important findings were demonstrated, which might be promising for developing of a new diagnostic approach to distinguish bacteria from yeasts. Addition of SiO2 beads to bacterial suspensions resulted in a significantly faster decrease of turbidity rates in comparison with corresponding suspensions without SiO2 beads. However, yeasts adhered to silica micro particles quicker in comparison with the speed of adherence of bacteria to silica.
