Zymomonas mobilis is an ethanologenic bacterium that has been studied for use in biofuel production. Of the sequenced Zymomonas strains, ATCC 29191 has been described as the phenotypic centrotype of Zymomonas mobilis subsp. mobilis, the taxon that harbors the highest ethanol-producing Z. mobilis strains. ATCC 29191 was isolated in Kinshasa, Congo, from palm wine fermentations. This strain is re...
Mathematical modeling of metabolism is essential for rational metabolic engineering. The present work focuses on several types of modeling approach to quantitative understanding of central metabolic network and energetics in the bioethanol-producing bacterium Zymomonas mobilis. Combined use of Flux Balance, Elementary Flux Mode, and thermodynamic analysis of its central metabolism, together wit...
The bacterium Zymomonas mobilis naturally produces ethanol at near theoretical maximum yields, making it of interest for industrial ethanol production. Zymomonas mobilis requires the vitamin pantothenate for growth. Here we characterized the genetic basis for the Z. mobilis pantothenate auxotrophy. We found that this auxotrophy is due to the absence of a single gene, panD, encoding aspartate-de...
Zymomonas mobilis subsp. mobilis is an efficient ethanol producer with application for industrial production of biofuel. To supplement existing Z. mobilis genomic resources and to facilitate genomic research, we used Oxford Nanopore and Illumina sequencing to assemble the complete genome of the beer spoilage isolate Z. mobilis subsp. mobilis strain NRRL B-1960.
BACKGROUND Inorganic mesoporous materials exhibit good biocompatibility and hydrothermal stability for cell immobilization. However, it is difficult to encapsulate living cells under mild conditions, and new strategies for cell immobilization are needed. We designed a "fish-in-net" approach for encapsulation of enzymes in ordered mesoporous silica under mild conditions. The main objective of th...
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...
Zymomonas mobilis is an alphaproteobacterium studied for bioethanol production. Different strains of this organism have been hitherto sequenced; they all belong to the Z. mobilis subsp. mobilis taxon. Here we report the finished and annotated genome sequence of strain ATCC 29192, a cider-spoiling agent isolated in the United Kingdom. ATCC 29192 is the lectotype of the second-best-characterized ...
Pyruvate decarboxylase (EC 4.1.1.1), the penultimate enzyme in the alcoholic fermentation pathway of Zymomonas mobilis, converts pyruvate to acetaldehyde and carbon dioxide. The complete nucleotide sequence of the structural gene encoding pyruvate decarboxylase from Zymomonas mobilis has been determined. The coding region is 1704 nucleotides long and encodes a polypeptide of 567 amino acids wit...
Regarding some reported antimicrobial properties of tannins; Zymomonas mobilis was used to obtain ethanol from tannin-reduced carob pod extract (TR-CPE). Culture of 50 mL volume containing 7.5 g sugar at pH 5.5 and 0.03 g bacterial inoculums with shaking at 80 rpm was used. Using response surface methodology (RSM), the maximum ethanol concentration of 5.34 % w/v (higher than that reported earli...
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...
