Sustainable algal biorefineries: capitalizing on many benefits of GABA

We provide physiological and met-abolic insights into the complex role of ?-aminobutyric acid (GABA) in fine-tuning algal metabolism to improve productivity. Genetic engi-neering strategies to improve algal GABA biosynthesis are also dis-cussed. Our aim is to provide an understanding of how GABA can be used for cost-competitive algae -based biofuels and bioproducts.
