This disclosure providesviolaxanthin de-epoxidase (CVDE) gene, polypeptides, and variants thereof as well as host cells that are genetically modified to express a CVDE polypeptide or variant. The disclosure additionally provides methods of producing such a genetically modified host cell and methods of using the cells , e.g., to increase zeaxanthin production.

[object Object]

Systems and methods are provided for using a growth vessel to simulate algae growth and/or productivity in a reference environment, such as an open pond, a closed photobioreactor, or a hybrid system. Based on predicted algae sample trajectories in the reference environment, an illumination profile is developed. An algae sample in the growth vessel can then be exposed to the illumination profile under controlled conditions. Properties of algae in the reference environment can then be characterized based on the sample exposed to the illumination profile.

Method of illuminating algae for algae growth

The invention provides a method of producing biomass or at least one biomolecule comprising culturing a photosynthetic microorganism that comprises a disrupted Non-Photochemical Quenching (NPQ) process, and isolating biomass or at least one biomolecule from the culture.
