摘要：

The continuous ethanol production from pineapple cannery waste by the respiration deficient strain Saccharomyces cerevisiae ATCC 24553 has been studied at 30 degrees C and pH 4.5. Maximum ethanol yield (92.5% of the theoretical) was obtained at a dilution rate of 0.05 h(-1). The maximum values for volumetric ethanol and biomass productivities were 3.75 g(p) l(-1) h(-1) and 0.63 g(x) l(-1) h(-1), respectively, at a dilution rate of 0.15 h(-1). The maintenance energy coefficient for S. cerevisiae ATCC 24553 was found to be 1.12 g(s) g(x)(-1) h(-1). The maximum specific ethanol productivity and specific sugar uptake rate were found to be (0.98 g(p) g(x)(-1) h(-1)) and (2.54 g(s) g(x)(-1) h(-1)), respectively. (C) 1999 Elsevier Science B.V.
