Ethanol was produced with Zymomonas mobilis Z6 (ATCC 29191), in batch culture with synthetic medium on glucose as substrate and in the presence of aspartate. The concentrations of glucose, phosphate, ammonium, ethanol and dissolved 0 2 and CO 2 in the medium and 02 and CO2 in the outlet gas as well
The influence of pH and medium composition on the production of ethanol by Zymomonas mobilis was investigated with fructose as substrate. The kinetic properties of the strain on fructose were as good as on glucose and pH 5.0 was found optimum. A mineral medium contaioing calcium pantothenate was des
