| Abstract: | Summary A chemically defined minimal medium which fulfils the growth requirements of differentZymomonasmobilis strains has been established. The kinetics of ethanol production of the strains ATCC 10988, CU1, CP4 and 11163 grown on the minimal medium at different glucose concentrations were measured. All strains produced ethanol at rates similar to those on complete medium. The minimal medium described is suitable to study spontaneous metabolic deficiciencies and regulation of enzyme activities inZ.mobilis. |
