Impacts of growth kinetics of sulfur-oxidizing Acidithiobacillus ferrooxidans on kinetic models

Popis výsledku v původním jazyce

The purpose of this study was to evaluate changes in kinetics of growth and elemental sulfur oxidation in Acidithiobacillus ferrooxidans cultures from the point of view of kinetic models of sulfuric acid formation. The values of maximum sulfur oxidationrate (v) and growth yield on sulfur (Y) were determined from data obtained in 86 batch cultures using bioreactors and shakers under the conditions described earlier. Both the constants demonstrated very different values in different cultures of the samestrain. No significant correlation between the v and Y values was observed. Two metabolic phases of ATP formation occurred. During the second one, the rate of cell growth did not correlate with the rate of ATP formation. The reasons for the above changesremain unclear. Whether or not the background of the kinetic changes is related to the natural property of sulfur metabolism in the studied strain or other sulfur-oxidizing bacteria remains to be determined. As a result of this, the comp
