Improved Technology for Mannitol Production

Executive SummaryIndustrialized production of mannitol for use as a food sweetener and various pharmaceutical applications is currently achieved by hydrogenation of a fructose/glucose syrup at high pressures and temperatures. The reaction produces a mixture of mannitol and sorbitol that is both inefficient (70% sorbitol as end-product) and requires...

Molecular Design of Thermostable Alcohol Dehydroganase for Synthesis for Chiral Aromatic Alcohols

IntroductionChiral aromatic alcohols are important building blocks for a variety of high-value chemicals, including pharmaceuticals, agrochemicals, and various other chiral compounds. Generally only one enantiomer is biologically active for the intended purpose of the drug; the other enantiomer can be toxic. To achieve enantiomeric purity using current...

Microbial Utilization of Electricity

IntroductionThe promotion of reductive processes in a biological system requires an electrochemical bioreactor system having a cathode compartment equipped with a cathode and an anode compartment equipped with an anode. The cathode and anode compartments are separated by a cation selective membrane, such that the cathode and anode are connected by a...
