Lactate and ethanol productions by Rhizopus oryzae ATCC 9363 and activities of related pyruvate branch point enzymes
In Rhizopus oryzae cultivations, lactate production decreased and ethanol and biomass productions increased as inoculated spore concentration increased. Spore concentrations of 1x10(3) and 1x10(4) spores ml(-1) induced tightly packed clumps, whereas 1x10(5) and 1 X 10(6) spores ml(-1) induced filamentous growth.
