Abstract: The present disclosure relates to methods of expressing therapeutic proteins in photosynthetic organisms and the therapeutic proteins produced by the methods. The therapeutic proteins include high-mobility group box 1 (HMGB1) protein, fibronectin domain (10) (10FN3), fibronectin domain (14) (14FN3), interferon beta (IFN?), proinsulin and vascular endothelial growth factor (VEGF). The photosynthetic organisms include prokaryotes such as cyanobacteria and eukaryotes such as alga and plants. Transformation of eukaryotes is preferably the plastid genome, more preferably the chloroplast genome.

Abstract: The present disclosure provides several novel genes that have been shown to increase the biomass yield or biomass of a photosynthetic organism. The disclosure also provides methods of using the novel genes and organisms transformed with the novel genes.

Abstract: Systems and methods for regulating optical power are described. A system for regulating optical power includes a laser driver circuit that receives an enable/disable signal and a data modulator input. The enable/disable signal regulates asynchronous mode operation. The system also includes a laser module including a laser diode emitter and a photodiode detector. The laser module is coupled to the laser driver circuit and receives a laser bias current from the laser driver circuit. The system also includes a switch coupled to the photodiode to receive a signal from the photodiode detector. The system also includes an automatic power control (APC) feedback circuit that receives a signal from the switch and provides a laser bias current feedback signal to the laser driver circuit to compensate for power output changes in the laser diode emitter over time.
