A new single-stage fermentation process for the commercial production of ethanol from refined sucrose, raw sugar, sugar cane juice, sugar cane syrup, sucrose hydrolysates and invert sugars has been developed using Zymomonas mobilis. The process gives a 94-98% sucrose hydrolysis efficiency and a 95-98% ethanol conversion efficiency. Within 24-30 hours, 200 g/L sucrose is converted to produce 95.5 g/L ethanol. Reinoculation is carried out from the fermented broth without the need for centrifugation or membrane filtration. |
