Synthetic Light‐Driven Consortia for Carbon‐Negative Biosynthesis

Synthetic light‐driven consortia composed of phototrophs and heterotrophs have attracted increasing attention owing to their potential to be used in sustainable biotechnology. In recent years, synthetic phototrophic consortia have been used to produce bulk chemicals, biofuels, and other valuable bioproducts. In addition, autotrophic‐heterotrophic symbiosis systems have potential applications in wastewater treatment, bioremediation, and as a method for phytoplankton bloom control. Here, we discuss progress made on the biosynthesis of phototrophic microbial consortia. In addition, strategies for optimizing the synthetic light‐driven consortia are summarized. Moreover, we highlight current challenges and future research directions for the development of robust and controllable synthetic light‐driven consortia. Synthetic light‐driven consortia are promising for biotechnological applications. However, challenges still exist with these promises. Here, we discuss the progress of phototrophic consortia in biosynthesis and summarize present challenges that obstruct the progress of synthetic phototrophic communities, along with some suggestions on future research directions to make synthetic light‐driven consortia more stable and controllable.
