Number	Title	Issue Date
5672504	Process for enriching an R,S!-1,2-epoxide in one enantiomer by using microbes to convert one enantiomer to the other or to preferentially open the epoxide ring A microorganism or a preparation thereof is permitted to act on a mixture of enantiomers of an epoxide such as 3-chlorostyrene oxide and the product optically active epoxide is recovered. The microorganism able to produce an optically active (S)-epoxide f...	09/30/1997
5486459	Biologically relevant methods for the rapid determination of sterility The invention is directed to biological processes and apparatus for determining the efficacy of a sterilization cycle based upon the recovery of activity of interactive enzyme systems comprising enzymes, coenzymes, catalysts, cofactors, substrates or any ...	01/23/1996
4734368	Process for the bioconversion of fumarate to L-malate L-malic acid is produced in a concentration of 170 to 400 g per liter and high yield by biotechnical conversion of fumaric acid neutralized with ammonium hydroxide in nutrient-free solution or suspension. Pure L-malic acid can be obtained economically the...	03/29/1988
3940315	Production of citric acid by submerged fermentation The invention concerns the production of citric acid-producing mycelial pellets of a citric acid-producing microorganism by a selective treatment with ferrocyanide or ferricyanide ions. Known Asperigillus or Penicillium are well suited for the fermentatio...	02/24/1976
