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 48h of anaerobic fermentation. After that,the PHB effect was observed as insignificant probably due to the exhaustion of the sugar.
