Researchers at the National Renewable Energy Laboratory (NREL) have been investigating the use of model photosynthetic microorganisms that use sunlight and two-carbon organic substrates (e.g., ethanol, acetate) to produce biodegradable polyhydroxyalkanoate (PHA) copolymers as carbon storage compounds. Use of these biological PHAs in single-use plastics applications, followed by their post-consumer composting or anaerobic digestion, could impact petroleum consumption as well as the overloading of landfills. The large-scale production of PHA polymers by photosynthetic bacteria will require large-scale reactor systems utilizing either sunlight or artificial illumination. The first step in the scale-up process is to quantify the microbial growth rates and the PHA production rates as a function of reaction conditions such as nutrient concentration, temperature, and light quality and intensity.
