title: [On the theory of the growth of germs as function of time and concentration (author's transl)].
abstract: The experimental harvest of germs is proportional to the amount of the minimal substrate. We formulate, therefore, the growth of germs as function of the employment of complete nutrient mediae containing all substrates required between two divisions. This conception may also be used for the function of time of the growth curve even beyond the log phase and allows a hard-and-fast rule for the region of nutritional deficiency. Our growth rates estimated as function of the concentration deviates from those established by Monod. This deviation can experimentally not be determined as the values of both estimations are in the experimental margin of tolerance. In contract to Monod's ferment conception implicating a growth of germs up to an unlimited dilution of nutrient mediae, our conception can more be recommended because of the defined beginning of growth.
