Hydroprocessing microalgal oils

Published online: Jul 30, 2010

Geographical region	USA
Subject	Production of fuel
Published date	Jul 8, 2010
Title	Hydroprocessing microalgal oils
Patent Application Number	US20100170144 A1
Assignee	Solazyme Inc, USA
Relevance	Method for producing fuels by hydroprocessing of microbial biomass.
Type of claims	Publication
Overview	This patent discloses a method for producing fuels from oil bearing microbial biomass via hydroprocessing and other chemical treatments. The method involves subjecting triglyceride oil isolated from microorganisms such as Prototheca, Chlorella, to chemical reactions such as hydrogenation, hydrodeoxygenation isomerization, transesterification etc., to generate fuels. Advantageously, the method is efficient and cost-effective and also enhances the production of products with relatively longer shelf-life. The method comprises, A) culturing a population of microbes, B) harvesting microbial biomass containing minimum 5% of lipid by dry cell weight, C) subjecting the biomass to a chemical reaction that covalently modifies minimum 1% of the lipid and D) separating the covalently modified lipid from other components of the biomass resulting in the production of fuel.
