Microbial Production of Glyceric Acid, an Organic Acid That Can Be Mass Produced from Glycerol
A method for the efficient biotechnological production of GA as a target compound for new surplus glycerol applications in the biodiesel and oleochemical industries is developed and suggests that mADH is involved in GA production by acetic acid bacteria. Expand
Production of Glyceric Acid by Gluconobacter sp. NBRC3259 Using Raw Glycerol
Gluconobacter sp. NBRC3259 converted glycerol to glyceric acid (GA). The enantiomeric composition of the GA produced was a mixture of DL-forms with a 77% enantiomeric excess of D-GA. After cultureExpand
Disruption of the Membrane-Bound Alcohol Dehydrogenase-Encoding Gene Improved Glycerol Use and Dihydroxyacetone Productivity in Gluconobacter oxydans
It was discovered that the G. oxydans mutant ΔadhA, in which the membrane-bound alcohol dehydrogenase-encoding gene (adhA) was disrupted, significantly improved its ability to grow in a higher concentration of glycerol and to produce DHA compared to a wild-type strain. Expand
Membrane-assisted extractive butanol fermentation by Clostridium saccharoperbutylacetonicum N1-4 with 1-dodecanol as the extractant.
A polytetrafluoroethylene (PTFE) membrane was used in membrane-assisted extractive (MAE) fermentation of acetone-butanol-ethanol (ABE) by Clostridium saccharoperbutylacetonicum N1-4 and it is expected that this MAE fermentation system can achieve footprint downsizing. Expand
Biotransformation of glycerol to d-glyceric acid by Acetobacter tropicalis
The enantiomeric composition of the produced GA was d-glyceric acid (d-GA), and the productivity of d-GA was enhanced with the addition of both 15% (v/v) glycerol and 20 g/l yeast extract. Expand
Biotechnological production of d-glyceric acid and its application
This mini-review provides recent information about the biotechnological production of a glycerol derivative, d-glyceric acid (d-GA), and its possible applications. Expand
Optical resolution of racemic 2-hydroxy octanoic acid using biphasic enzyme membrane reactor
A lipase-immobilized biphasic membrane reactor was applied for the optical resolution of racemic 2-hydroxy octanoic acid. Lipase from Candida rugosa or Pseudomonas cepacia was used as a biocatalyst,Expand
An amorphous alloy membrane without noble metals for gaseous hydrogen separation
Abstract Hydrogen-permeable membranes have a variety of industrial applications but all of the metal membranes employed in industry are made of palladium or palladium alloys. We have been looking forExpand
Solubility of .beta.-carotene in dense carbon dioxide and nitrous oxide from 308 to 323 K and from 9.6 to 30 MPa
A one-pass flow system was used to measured the solubilities of β-carotene (C 40 H 56 ) in dense carbon dioxide and nitrous oxide. The solubillities established at 308, 313, 318, and 323 K andExpand
Improved crown ether-based chiral stationary phase
Abstract An improved crown ether-based chiral stationary phase (CSP) was prepared by dynamic coating of a reversed-phase silica gel with a new chiral crown ether which was designed to have moreExpand
