Abstract

A method for cultivating fast growing bacteria and their stable metabolites in order to reach optimal cultivating time is disclosed which comprises introducing a volume of inoculum containing the bacterium sought to be cultivated and a quantity of nutriment containing a nitrogen source, growing factors, a carbon source, and a pH-stabilizer into a fermentor. The volume of inoculum in the fermentor is utilized as a production determinative factor and is determined according to the following equation:wherea = volume of inoculum in litersV = cultivating medium's total volume in litersn = bacterium strain's generation time in hourst = cultivating time in hours.The result is that a grown cultivating medium is obtained which includes a mass of the desired bacterium.
