Title
(EN) PHOTOSYSTEM I-HYDROGENASE CHIMERAS FOR HYDROGEN PRODUCTION
Abstract
(EN)

Provided herein, in some embodiments, are engineered cells and use of the same for increased hydrogen production. In particular, provided herein are genetically engineered cells comprising a polynucleotide encoding a fusion protein comprising a photosystem I (PSI) protein and an algal hydrogenase, as well as methods for producing such genetically engineered cells. Also provided herein are methods for increasing hydrogen (H2) production in cells.
