[Effect of light-isotope water on growth of bacterial culture]

The stimulating effect of light-isotope water on microbial growth was demonstrated in bacterial culture Pseudomonas esterophilus. Nutrient medium was prepared of mineral salts and ethyl acetate as a source of carbon dissolved in light-isotope water with ppm 35 and 70; the control medium contained same components dissolved in distilled water. The investigation showed an increase in the number of bacterial cells in the exponential stage of growth in static culture in light-isotope water as compared with the control. Specifically, accretion made up 87.3 and 35.2% in light-isotope water with ppm 35 and 70, respectively. In an hour, the number of cell divisions increased by 6.7% and 3.3%, respectively. Therefore, light-isotope water stimulates the metabolic activity and, consequently, growth of bacterial cells.
