Abstract Zymonomas mobilis was transformed with a polyhydroxybutyrate synthesis operon phbCAB equipped with a pdc promoter from Z. mobilis. For the first time, PHB was produced in recombinant Z.mobilis. Shake flask studies indicated that accumulation of PHB in Zymomonas mobilis increased approximately 10% ethanol productivity for the first 48 h of anaerobic fermentation. After that, the PHB effect was observed as insignificant probably due to the exhaustion of the sugar.

Key words： PHB Zymonomas mobilis Ethanol Polyhydroxybutyrate
