Photobiological production of high-value pigments via compartmentalized co-cultures using Ca-alginate hydrogels.

Engineered cyanobacterium Synechococcus elongatus can use light and CO to produce sucrose, making it a promising candidate for use in co-cultures with heterotrophic workhorses. However, this process is challenged by the mutual stresses generated from the multispecies microbial culture. Here we demonstrate an ecosystem where S.
