The invention relates to methods for producing lipids such as fatty acid products in recombinant host cells engineered to express a non-native gene encoding a dehydrogenase. The recombinant microorganisms are able to proliferate at a higher rate as compared with microorganisms that do not express a non-native dehydrogenase gene, and cultures of microorganisms that are engineered for lipid production and that express a non-native dehydrogenase produce more lipid than cultures of control microorganisms that do not include a non-native dehydrogenase gene.

Cell systems and methods for improving fatty acid synthesis by expression of dehydrogenases

The invention provides transgenic photosynthetic microorganisms that include non-native genes encoding polypeptides having lipolytic activity for production of free fatty acids and fatty acid derivatives, and methods of producing free fatty acids and fatty acid derivatives using the transgenic microorganisms disclosed herein. The invention also provides transgenic microorganisms that include non-native genes encoding polypeptides having lipolytic activity, and novel genes encoding polypeptides demonstrating lipolytic activity.

Production of fatty acids and fatty acid derivatives by recombinant microorganisms expressing polypeptides having lipolytic activity

The invention relates to acyl-CoA-independent methods of producing fatty alcohols in recombinant host cells engineered to express an alcohol-forming acyl-ACP reductase. The recombinant host cells may be photosynthetic microorganisms, such as cyanobacteria. Isolated nucleic acid molecules, vectors, and recombinant host cells expressing an alcohol-forming acyl-ACP reductase, and systems for producing fatty alcohols via an acyl-CoA-independent pathway, are also provided. Also provided are microorganisms engineered for the secretion of fatty acids and fatty acid derivatives, including fatty alcohols, and methods of producing fatty acid derivatives using such engineering microorganisms.

Production and secretion of fatty acids and fatty acid derivatives

The present invention provides novel diacylglycerol acyltransferase (DGAT) genes comprising Pleckstrin Homology (PH) domains. The present invention also provides for recombinant cells, such as algae, transformed with acyltransferase genes, such as DGAT, comprising PH domains, and methods of using such recombinant cells to produce increased triglyceride levels.
