Whether the feedstock is sugarcane, corn, or lignocellulose, the fermentation and ethanol recovery operations are similar. The differences arise in the way the sugars are released and the co-products produced.
The individual technical elements of the algae-to-biofuels process have already been demonstrated at the laboratory scale. Ongoing research seeks to refine the technology to enable scaleup to commercial production.

Biochemical and thermochemical process technologies being developed to convert wood and other lignocellulosic feedstocks to liquid fuels will drive the transition from corn-based ethanol to advanced biofuels.
The use of complex living organisms, process variation, and lack of real-time measurements of key parameters are some of the challenges involved in automating a bioprocess. This article explains an indirect approach to monitoring and controlling a...
