Advanced Solid State Fermentation for Cost-effective Production of Bioethanol from Sweet Sorghum Stalks
Solid state fermentation has attracted more and more attention with advantages of higher volumetric productivity, lower energy requirements, and simplified process over submerged liquid state fermentation, especially for biofuels (eg. bioethanol) production from sugar feedstocks. However, solid-state fermentation has some shortcomings. For instance, it is out of date for conventional technology and equipment, no way to monitor the course of fermentation on line, hard to realize the automatic control. This talk will present an advanced study on solid state fermentation technique with a successful example of a 10,000-metric ton (MT) scale sweet sorghum ethanol plant equipped with 550 m3 advanced rotary drum fermenters, the largest solid-state fermenter used in fuel ethanol production in the world. It is highly feasible for sweet sorghum and other sugar feedstocks like sugar cane to adopt this technique to establish a new industry of renewable fuel and cattle feed in Queensland/Australia.
