Chlorella species containing exogenous genes
First Claim
1. A triglyceride oil produced by cultivating heterotrophically in the dark a genetically engineered Chlorella protothecoides cell comprising an exogenous gene encoding a sucrose invertase, wherein the exogenous gene is codon optimized for expression in the Chlorella protothecoides cell;
- wherein the cell is cultured on a fixed carbon source selected from the group consisting of glycerol, depolymerized cellulosic material, sucrose, molasses, glucose, galactose, fructose, mannose, acetate, and any combination thereof.

Abstract
The invention provides methods of cultivating oil-bearing microbes using xylose alone or in combination with other depolymerized cellulosic material. Also provided are microorganisms comprising an exogenous gene encoding a polysaccharide degrading enzyme, such as a cellulase, a hemicellulase, a pectinase, or a driselase. Some methods of microbial fermentation are provided that comprise the use of xylose and depolymerized cellulosic materials for the production of oil-bearing microorgansims.
