Abstract 

Since germanium has been shown to be beneficial for the treatment of diseases such as cancer and rheumatic arthritis, we developed an adapted process of bio-germanium preparation using inorganic gennanium. In the present study we determined the optimal conditions for culturing yeast Saccharomyces cerevisiae (KCTC-1199), and the best concentrations of inorganic germanium for the adaptation process. The resulting method was successful at producing high quantities of germanium yeasts. The following are the culture conditions that obtained the highest level of productivity: an inorganic germanium concentration of 3,000-5,000 ppm, a pH of 6.5, a temperature of 35°C, and 20 hr of incubation time. In addition to this high-yield quantity study, we observed the acute oral toxicity of mice treated with Geranti Bio-Ge Yeast®. We found no changes in body weight, or in the mortality between the control groups and the bio-germanium yeast group. There were also no digestive problems such as diarrhea that occurred in either group.
