This work forms part of an on-going long term project to develop a two stage continuous ethanol fermentation process at 70°C using Bacillus stearothermophilus LLD-15, an L-lactic acid dehydrogenase mutant of a novel extreme thermophile, B. stearothermophilus PSII. The process is envisaged to consist of a first stage for aerobic biomass production and a second stage for the biocatalytic conversion of carbohydrate(s ) to ethanol with a biomass feedback from the anaerobic stage to the aerobic stage. The greater proportion of the ethanol produced will be in the vapour phase and will be removed by continuously sparging the fermenter with an inert gas, probably nitrogen.
