Biological oils and production and uses thereof

Published online: Jul 26, 2010

Geographical region	Europe
Subject	Production of Biodiesel
Published date	Jun 23, 2010
Title	Biological oils and production and uses thereof
Patent Application Number	EP2198038 A1
Assignee	Martek Biosciences Corp, USA
Relevance	Process for producing biological oils from feedstock by heterotrophic fermentation using a microorganism.
Type of claims	Publication
Overview	This patent discloses a process for the production of biological oils that include lipid-based biofuels and fuel additives from cellulose-containing feedstock by fermentation using microorganisms such as Stramenopiles, Crypthecodinium, Cryptococcus, etc. The biological oil is obtained by autolysis or induced lysis of the microorganism using mechanical forces, enzyme, detergent, etc. Advantageously, the two-stage fermentation process increases the efficiency, enhances large-scale production of lipid-based biofuel production, and is cost effective and commercially feasible. The method comprises, A) growing a microorganism by heterotrophic fermentation using feedstock comprising cellulose as a carbon source to produce a biological oil, wherein about 11% to about 99% of unsaturated fatty acids in the biological oil are polyunsaturated fatty acids, and B) transesterifying the biological oil to produce biodiesel.
