Ablog by patent attorney Lawrence B. Ebert notes the first claim of US 7,905,930 issued to Genifuel on March 15, 2011 for “A process for production of biofuels from algae, comprising: a) cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth, b) producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae; and c) extracting an algal oil from the oil-producing algae.”

The priority claim: This application claims the benefit of U.S. Provisional Patent Application No. 60/877,786, filed on Dec. 29, 2006, which is incorporated by reference herein in its entirety.

US application: 11/966,917 The abstract: “A process for production of biofuels from algae can include cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth. The method can further include producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae. An algal oil can be extracted from the oil-producing algae, and can be converted to form biodiesel.” As the first step of the process requires: “by promoting sequential photoautotrophic and heterotrophic growth,” relative to Solazyme’s production process, Ebert points out that unlike other algae-based biofuel companies, Solazyme does not grow algae with photosynthesis. Rather, they use a genetically modified strain that feeds on sugar in a fermentation process.
