  • Chewing gum composition for effectively eliminating nicotine accumulated in a human body
    Patent number: 6958143
    Abstract: Disclosed is a chewing gum composition capable of eliminating nicotine component from the body of a person chewing the chewing gum. Such a chewing gum composition functions to convert the nicotine produced in a human body after smoking to cotinine and to discharge the cotinine into urine. Accordingly, by chewing the chewing gum of the present invention, not only nicotine can be eliminated from the body, but also the incidence of cancer due to nicotine can be largely reduced.

  • Biological tagatose production by recombinant Escherichia coli
    Publication number: 20030235894
    Abstract: This invention relates to a recombinant Escherichia coli and a process for producing D-tagatose. In detail, it includes the construction of recombinant E.coli harboring L-arabinose isomerase, whole-cell conversion of D-galactose into D-tagatose by recombinant E.coli expressing L-arabinose isomerase, enzymatic production of D-tagatose by the extract of recombinant E.coli expressing L-arabinose isomerase, and bioconversion by immobilized L-arabinose isomerase.

  • Novel thermostable galactose isomerase and tagatose production thereby
    Publication number: 20030175909
    Abstract: Disclosed are novel thermostable galactose isomerases and production of tagatose using the same. A gene encoding a galactose isomerase with improved thermal stability and reaction equilibrium is screened from natural genetic materials. An expression vector into which the gene is inserted is introduced into bacteria which are then cultured to obtain a thermostable galactose isomerase. In the presence of this enzyme, tagatose is produced from galactose in a yield as high as 46-50% at a temperature as high as 55° C.
