The economics of butanol fermentation has been given considerable attention and the high cost of carbon sources has
been identified as a major factor affecting the economic viability of the large-scale ABE fermentation. Previous reports show that substrate cost accounted for up to 79% of the solvent production costing a conventional ABE fermentation (Green, 2011; Pfromm et al., 2010). Cassava as a carbon source in butanol production has attracted much attention during the past three decades because it is a high-yield, non-grain crop, and can grow in dry and poor soils, avoiding land competition with other major food crops (Jansson et al., 2009). It can be expected that butanol production
cost could be decreased when the cheap carbon source cassava is used. Moreover, a continuous ABE production accomplished by a fermentation–PV coupled process would further decrease the cost if the solvent toxicity to the microorganism could be alleviated by in situ removal of butanol from fermentation broth and consequently
the productivity could be increased. To the best of our knowledge, there is no report on continuous butanol production
from cassava by a fermentation–PV coupled process.
