Pseudomonas oleovorans has been previously shown to produce a polyester containing a phenyl pendant group when grown with 5‐phenylpentanoic acid under nutrient‐limiting conditions. The same polyester was produced when 5‐phenyl‐2,4‐pentadienoic acid was the only carbon source, and a mixture of two different polymers was produced when this bacterium was grown on a mixture of 5‐phenyl‐2,4‐pentadienoic acid and nonanoic acid. The polymer blend obtained was separated by fractional crystallization to yield poly(3‐hydroxy‐5‐phenylpentanoate) and the copolymer which is normally produced with nonanoic acid alone.
