Ralstonia eutrophais a hydrogen-oxidizing chemolithotrophic bacterium that can synthesize poly[(R)-3-hydroxybutyrate] [P(3HB)], which is used as a biodegradable plastic. Various genes coding for carbonic anhydrase (CA), which are involved in CO2fixation and metabolism, are present in the genome ofR. eutropha. Although the significance of CA for CO2metabolism inR. eutrophais well known, CAs have never been deliberately employed to enhance P(3HB) production from CO2. Thus, we investigated the gene dosage effect of the β-carbonic anhydrase (can) gene on P(3HB) accumulation inR. eutrophaH16 under autotrophic and mixotrophic conditions. The multicopy plasmid-based dosage of thecangene showed a 1.5-fold increase in P(3HB) content in cells grown under nitrogen-source-limited autotrophic conditions. A similar result was observed under nitrogen-source-limited mixotrophic conditions in the presence of glycerol. Thus, these findings suggest a viable strategy to increase P(3HB) yield under autotrophic and mixotrophic culture conditions.
