Molecular Methods Used for the Identification of Potentially Probiotic Lactobacillus reuteri Strains

Autor: Agnes Weiss, Hans Peter Lettner, Walter Kramer, Wolfgang Kneifel, Helmut Karl Mayer

Publikováno v: Food Technology and Biotechnology, Vol 43, Iss 3, Pp 295-300 (2005)

Forty potentially probiotic Lactobacillus strains as well as reference strains of different genera were grown under standardised conditions. Cell masses were harvested and DNA was isolated. For identification, all strains were subjected to genus-spec

Purification and Characterization of Two Novel β-Galactosidases from Lactobacillus reuteri

Autor: Wolfgang Kneifel, Thu-Ha Nguyen, Marlene Steinböck, Barbara Splechtna, Klaus D. Kulbe, Dietmar Haltrich, Hans Peter Lettner

Publikováno v: Journal of Agricultural and Food Chemistry. 54:4989-4998

The intracellular beta-galactosidase (beta-gal) enzymes from two strains of Lactobacillus reuteri, L103 and L461, were purified by ammonium sulfate fractionation, hydrophobic interaction, and affinity chromatography. Both enzymes are heterodimers wit

HETP in Process Ion-Exchange Chromatography

Autor: Oliver Kaltenbrunner, Hans Peter Lettner, Alois Jungbauer

Publikováno v: Journal of Chromatographic Science. 33:451-457

The expression height equivalent to one theoretical plate (H) is a quality parameter in (process-) chromatography for column packing and particle size distribution of resins. It is found that the value of H, ubiquitously known and accepted by chemica
