Abstract

Official abstract text for this publication.

Disclosed is a method for producing biodegradable polymer and ethanol converted from carbon source by using recombinant microorganisms, comprising the steps of: (A) providing recombinant microorganisms transformed with plasmids containing at least a gene encoding for glycerol utilizing enzyme and a gene encoding for polyhydroxyalkanoate synthase; (B) culturing the recombinant microorganisms in a medium containing glycerol; (C) inducing expression of the genes of step (A), thereby obtaining polyhydroxyalkanoate and ethanol; and (D) recovering the polyhydroxyalkanoate and the ethanol; wherein the recombinant microorganisms have a glycerol utilization rate more than 90% (w/w), and have polyhydroxyalkanoate accumulated therein to a biomass content thereof at least 30% (w/w).

First claim

Opening claim text (preview).

What is claimed is: 1. A method for producing biodegradable polymer and ethanol converted from carbon source, comprising the steps of: (A) providing E. coli DSM 27723, said E. coli DSM 27723 containing plasmids encoding aldehyde reductase (alrd), aldehyde dehydroxygenase (aldH), and PhaCAB polyhydroxyalkanoate synthase; (B) culturing the E. coli DSM 27723 in a medium containing glycerol; (C) inducing expression of the E. coli DSM 27723 plasmid encoded aldehyde reducta…
