A mutant strain of Klebsiella pneumoniae, termed GEM167, was obtained by γ irradiation, in
which glycerol metabolism was dramatically affected on exposure to γ rays. Levels of …

To improve production of ethanol from glycerol, the methylotrophic yeast Hansenula
polymorpha was engineered to express the pdc and adhB genes encoding pyruvate …

Lactic acid bacteria are candidates for engineered production of ethanol from biomass
because they are food-grade microorganisms that can, in many cases, metabolize a variety …

Recently, novel Klebsiella pneumoniae J2B, which grows rapidly on glycerol as the carbon
source without forming pathogenic and sticky lipopolysaccharides, was isolated. Current …

In the present work, mutant strains of Klebsiella pneumoniae with deletions of the als gene
encoding acetolactate synthase involved in synthesis of 2, 3-butanediol, the ldhA gene …

Abstract The production of 1, 3-propanediol (1, 3-PDO) from glucose was investigated using
Klebsiella pneumoniae J2B, which converts glycerol to 1, 3-PDO and synthesize an …

The main objective of this research is to develop, by adaptive evolution, mutant strains of
Enterobacter aerogenes ATCC 13048 that are capable of withstanding high glycerol …

An ethanol-tolerant mutant, ET1, was isolated by an enrichment method from Escherichia
coli JM109. Strains JM109 and ET1 were transformed with expression vector pZY507bc …

Bioethanol is a promising biofuel and has a lot of great prospective and could become an
alternative to fossil fuels. Ethanol fermentation using glycerol as carbon source was carried …

We report on engineering Escherichia coli to produce ethanol at high yield from gluconic
acid (gluconate). Knocking out genes encoding for the competing pathways (l-lactate …
