Screening of lipases for the enantiomer resolution of R,S-2-octanol by esterification in organic medium
Autor: Peter Schreier, Doris Gerlach, Cornelia Missel
Publikováno v: Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung. 186:315-318
Eleven commercially available lipase preparations of microbial and animal origin were screened for enantiomer resolution of R,S-2-octanol by esterification with dodecanoic acid in heptane. The influence of temperature, substrate/enzyme ratio and reac

Esterification in Organic Media for Preparation of Optically Active Secondary Alcohols: Effects of Reaction Conditions
Autor: Doris Gerlach, Peter Schreier
Publikováno v: Biocatalysis. 2:257-263
Esterification in an organic solvent for enantioselective preparation of optically active secondary alcohols was investigated using porcine pancreas lipase (PPL), (R,S)-2-octanol and dodecanoic acid in heptane. The influence of different reaction con

Embryo- und Endospermentwicklung nach einer Röntgenbestrahlung der Fruchtknoten von Arabidopsis thaliana (L.) heynh
Autor: Doris Gerlach-Cruse
Publikováno v: Radiation Botany. 9:433-442
Zusammenfassung Nach einer Bestrahlung der Fruchtknoten von Arabidopsis thaliana mit Rontgenstrahlen (56 kV 2 mA, Filter 0,1 mm Al) und anschliessender Bestaubung der Narben mit unbestrahltem Pollen werden neben einer normalen Befruchtung folgende Ab

Enantioselective lipase catalyzed esterification in organic medium for preparation of optically active secondary alcohols
Autor: Doris Gerlach, Detlef Lutz, Boris Mey, Peter Schreier
Publikováno v: Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung. 189:141-143
The homologous series of aliphatic 2-alkanols (2-pentanol to 2-decanol) and three phenylalkanols (1-phenylethanol; 1-phenyl-l-propanol; 1-phenyl-2-propanol) were prepared in high chemical (40–80% of theoretical value) and optical yields (78–100%

New border control system for food originating from third world countries
Autor: Matthias Heinzler, Doris Gerlach, Hubertus Brunn
Publikováno v: Environmental Sciences Europe. 23(1):14
The global distribution of food products has created a requirement for inspection and testing of imported goods at national and outer European borders. Problems that are generally not encountered with local produce arise when dealing with imports fro
