The genome of Pelobacter carbinolicus reveals surprising metabolic capabilities and physiological features.
BMC Genomics 13 , 690, (2012) The bacterium Pelobacter carbinolicus is able to grow by fermentation, syntrophic hydrogen/formate transfer, or electron transfer to sulfur from short-chain alcohols, hydrogen or formate; it does not oxidize acetate and is not known to ferment any sugars or g... |

Identification of factors regulating Escherichia coli 2,3-butanediol production by continuous culture and metabolic flux analysis.
J. Microbiol. Biotechnol. 22(5) , 659-67, (2012) 2,3-Butanediol (2,3-BDO) is an organic compound with a wide range of industrial applications. Although Escherichia coli is often used for the production of organic compounds, the wild-type E. coli does not contain two essential genes in the 2,3-BDO biosynthes... |

Medium optimization and proteome analysis of (R,R)-2,3-butanediol production by Paenibacillus polymyxa ATCC 12321.
Appl. Microbiol. Biotechnol. 97(2) , 585-97, (2013) Paenibacillus polymyxa can produce the (R,R)-stereoisomer of 2,3-butanediol (2,3-BDL) which is industrially very useful. Two important factors affecting (R,R)-BDL production by P. polymyxa ATCC 12321, medium composition, and addition of acetic acid to the cul... |

Thermal expansion of the cryoprotectant cocktail DP6 combined with synthetic ice modulators in presence and absence of biological tissues.
Cryobiology 65(2) , 117-25, (2012) This study explores physical effects associated with the application of cryopreservation via vitrification using a class of compounds which are defined here as synthetic ice modulators (SIMs). The general classification of SIMs includes molecules that modulat... |

Biocatalytic production of alpha-hydroxy ketones and vicinal diols by yeast and human aldo-keto reductases.
Chem. Biol. Interact. 202(1-3) , 195-203, (2013) The α-hydroxy ketones are used as building blocks for compounds of pharmaceutical interest (such as antidepressants, HIV-protease inhibitors and antitumorals). They can be obtained by the action of enzymes or whole cells on selected substrates, such as diketo... |

Fermentation of biodiesel-derived glycerol by Bacillus amyloliquefaciens: effects of co-substrates on 2,3-butanediol production.
Appl. Microbiol. Biotechnol. 97(17) , 7651-8, (2013) Cultivation in glycerol instead of sugars inhibits 2,3-butanediol (2,3-BD) production by Bacillus amyloliquefaciens. In this study, we report that B. amyloliquefaciens readily produces 2,3-BD from biodiesel-derived glycerol in the presence of beet molasses as... |

Removal of pathogenic factors from 2,3-butanediol-producing Klebsiella species by inactivating virulence-related wabG gene.
Appl. Microbiol. Biotechnol. 97(5) , 1997-2007, (2013) Klebsiella species are the most extensively studied among a number of 2,3-butanediol (2,3-BDO)-producing microorganisms. The ability to metabolize a wide variety of substrates together with the ease of cultivation made this microorganisms particularly promisi... |

Cloning, expression and characterization of meso-2,3-butanediol dehydrogenase from Klebsiella pneumoniae.
Biotechnol. Lett. 34(8) , 1519-23, (2012) The budC gene encoding the meso-2,3-BDH from Klebsiella pneumoniae XJ-Li was expressed in E. coli BL21 (DE3) pLys. Hypothetical amino acid sequence alignments revealed that the enzyme belongs to the short chain dehydrogenase/reductase family. After purificati... |

2,3-Butanediol recovery from fermentation broth by alcohol precipitation and vacuum distillation.
J. Biosci. Bioeng. 117(4) , 464-70, (2014) This study presents a new and effective downstream process to recover 2,3-butanediol (2,3-BD) from fermentation broth which is produced by a recombinant Klebsiella pneumoniae strain. The ldhA-deficient K. pneumoniae strain yielded about 90 g/L of 2,3-BD, alon... |

Metabolic engineering of Bacillus subtilis for enhanced production of acetoin.
Biotechnol. Lett. 34(10) , 1877-85, (2012) Acetoin is widely used in food and other industries. A bdhA and acoA double-knockout strain of Bacillus subtilis produced acetoin at 0.72 mol/mol, a 16.4 % increased compared to the wild type. Subsequent overexpression of the alsSD operon enhanced the acetola... |
