Summary: The genome sequence and protocols for genetic manipulation for Nannochloropsis
gaditana, a microalga that has high lipid and biomass production
Description: The potential use of algae in biofuel applications has received significant attention.
However, none of the current algal model species are competitive production strains. This
invention discloses a novel genome sequence and a method for genetic transformation of the
marine microalga, Nannochloropsis gaditana. This particular microalga has highly favorable lipid
yields, and is a promising production organism. Native promoters from N. gaditana for the
transgenic expression of genes have been identified and tested. This method can be used to
express both the native and foreign genes for improved production properties with regards to
biofuels and other high-value products.
Main Advantages of this Invention
 Robust producer of biomass and lipids
 Highly productive strain
Potential Areas of Application
 Biofuel production
 Lipid production
