The thermoanaerobe, Caloramator boliviensis was used to ferment starch hydrolysate from inedible wild cassava to ethanol at 60 oC. A raw starch degrading a-amylase was used to hydrolyse the cassava starch. During the fermentation, the organism released CO2 and H2 gases. An early prototype of Gas Endeavour® was used for monitoring and recording formation of these gaseous products. The bioethanol produced in stoichiometric amounts to CO2 was registered online in Gas Endeavour® and correlated strongly (R2=0.99) with values measured by HPLC.
