A Nitrate-Blind P. putida Strain Boosts PHA Production in a Synthetic Mixed Culture.

ABSTRACT: One of the major challenges for the present and future generations is to find suitable substitutes for the fossil resources we rely on today. In this context, cyanobacterial carbohydrates have been discussed as an emerging renewable feedstock in industrial biotechnology for the production of fuels and chemicals. Based on this, we recently presented a synthetic bacterial co-culture for the production of medium-chain-length polyhydroxyalkanoates (PHAs) from CO₂. This co-cultivation system is composed of two partner strains: Synechococcus elongatus cscB which fixes CO₂, converts it to sucrose and exports it into the culture supernatant, and a Pseudomonas putida strain that metabolizes this sugar and accumulates PHAs in the cytoplasm. However, these biopolym
