Secretive expression of heterologous β-glucosidase in Zymomonas mobilis
Background: Zymomonas mobilis is an efficient ethanol fermentation strain, but its narrow substrate range limits its fermentation in lignocellulose hydrolysate. As a potential consolidated bioprocessing (CBP) stain for bioethanol production, the ability of cellulose utilization was necessary. In this study, extracellular expression of β-glucosidase on Z. mobilis was studied as the first step fo...
متن کاملConstruction of an integrative shuttle vector for Zymomonas mobilis.
An integrative shuttle vector, pZMOCP1, was constructed by ligating EcoRV digests of the plasmid cloning vector pBluescript and pZMP1, a cryptic plasmid of Zymomonas mobilis PROIMI A1. The 7.2-kb plasmid pZMOCP1 replicated in Escherichia coli and could also be transferred from this host by electroporation to Z. mobilis ATCC 29191. The transformants were selected by ampicillin resistance. The in...
متن کاملHeterologous expression and extracellular secretion of cellulolytic enzymes by Zymomonas mobilis.
Development of the strategy known as consolidated bioprocessing (CBP) involves the use of a single microorganism to convert pretreated lignocellulosic biomass to ethanol through the simultaneous production of saccharolytic enzymes and fermentation of the liberated monomeric sugars. In this report, the initial steps toward achieving this goal in the fermentation host Zymomonas mobilis were inves...
متن کاملGlycolytic enzymes in Zymomonas mobilis.
Raps, Shirley (University of Illinois, Urbana) and R. D. DeMoss. Glycolytic enzymes in Zymomonas mobilis. J. Bacteriol. 84:115-118. 1962-An enzyme extract of Zymomonas mobilis (Pseudomonas lindneri) was capable of fermenting glucose-6-phosphate to CO(2) and ethanol. The extract was found to contain phosphohexoisomerase, aldolase, and glyceraldehyde-3-phosphate dehydrogenase, but no demonstrable...
متن کاملDifferential Expression of Zymomonas mobilis Sucrase Genes (sacB and sacC) in Escherichia coli and Sucrase Mutants of Zymomonas mobilis
The sacB and sacC genes encoding levansucrase and extracellular sucrase respectively were independently subcloned in pBluescript (high copy number) and in Z. mobilis-E. coli shuttle vector, pZA22 (low copy number). The expression of these genes were compared under identical background of E. coli and Z. mobilis host. The level of sacB gene expression in E. coli was almost ten fold less than the ...
