Spezielle Aspekte der nichtsterilen Hefeproduktion auf der Basis von Kohlenwasserstoffen

Some aspects of the nonsteril yeast production are shown by a process with the alkane utilizing yeast Lodderomyces elongisporus D EH 15. Thereby an accompanying flora developes besides the yeast culture. The accompanying flora is using a lot of biogenic substances which are lysis products or extracellular metabolites. The dynamics of the development of the accompanying flora are shown, some remarks are made concerning the interactions between production strain and bacteria, the stability of the yeast strain and the recirculation of process water streams after the separation.
