Optimization of Culture Conditions for 1,3-Propanediol Production from Glycerol Using a Mutant Strain of Klebsiella pneumoniae
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 encoding lactate dehydrogenase req...

Stimulation of reductive glycerol metabolism by overexpression of an aldehyde dehydrogenase in a recombinant Klebsiella pneumoniae strain defective in the oxidative pathway
Previously, we constructed a glycerol oxidative pathway-deficient mutant strain of Klebsiella pneumoniae by inactivation of glycerol dehydrogenase (dhaD) to eliminate by-product synthesis during production of 1,3...

Enhanced production of ethanol from glycerol by engineered Hansenula polymorpha expressing pyruvate decarboxylase and aldehyde dehydrogenase genes from Zymomonas mobilis
To improve production of ethanol from glycerol, the methylotrophic yeast Hansenula polymorpha was engineered to express the pdc and adhB genes encoding pyruvate decarboxylase and aldehyde dehydrogenase II from Zy...

Improved ethanol tolerance in Escherichia coli by changing the cellular fatty acids composition through genetic manipulation
To investigate the effect of cellular fatty acids composition on ethanol tolerance in Escherichia coli, we overexpressed either des, encoding fatty acid desaturase from Bacillus subtilis, or fabA, encoding β-hydr...
