Abstract
Provided herein are methods for generating cellular biomass in continuous aerobic fermentation systems. The biomass yield, and the concentration of polyhydroxyalkanoate within the biomass, are each directed to advantageous levels by operating the continuous fermentation system under particular nutrient limitation conditions. Also provided are biomass produced using the provided methods, and animal feed compositions including the provided biomass.
