Solazyme said it has achieved commercial-scale algae-based oil production at a fermentation plant owned by Archer Daniels Midland in Iowa. Solazyme made renewable oil in 132,000-gallon containers at the facility, the company said. "Solazyme's fermentations have reached a scale that, to our knowledge, is the highest level of any algae-based company in the world," said analyst Pavel Molchanov of Raymond James & Associates.
