Abstract

The scale-up of column fermenters [for ethanol fermentation from sugar cane bagasse by Schwanniomyces castellii CBS 2863] by 6 to 410 gravimetric scale factors from 10 g moist substrate size was achieved efficiently by maintaining heat and water balances in the media. Data on patterns of ethanol production, biomass formation, the concn. of different carbohydrates, DM and pH values against time were of equal magnitude in 10- and 60-g size column fermenters. Reactors of 60-, 370- and 4100-g sizes also compared well in respect of O2 consumption, CO2 evolution and the specific growth rates in aerobic and anaerobic fermentation phases. Overall productivities of ethanol were similar in all the 4 column fermenters. The ability to obtain the same results in all the fermenter sizes, in spite of increases in diam. and the height of the columns, indicates the high potential of this simple scale-up criterion which has not been used earlier for scale-up of any fermentation process.
