Abstract
The present invention provides a mutant algal microorganism that has a mutation that causes attenuated expression of TrifuncB and/or TrifuncA and as a result produces more lipids than a control algal microorganism. The mutant algal microorganism can further include a mutation in a gene encoding a peroxisomal beta-oxidation pathway protein, such as an ACO1 or PXA1 gene, or a glyoxylate pathway protein, such as an ICL1 gene, that results in attenuated expression and further increased lipid production. Furthermore, provided herein are methods of producing lipids using the mutant algal microorganisms and methods of making the mutant microorganisms.
Claims23
A Eustigmatophyte algal microorganism comprising a disruption in a gene encoding a mitochondrial trifunctional protein subunit B (TrifuncB) having at least 90% sequence identity to SEQ ID NO:
- 10 and/or mitochondrial trifunctional protein subunit A (TrifuncA) having at least 90% sequence identity to SEQ ID NO:
- 1, wherein the microorganism produces more fatty acid methyl ester-derivatizable lipids (FAME lipids) on a per volume per day basis than a control microorganism of the same species.
