Abstract

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.
