Bêta-galactosidases et phospho-bêta-galactosidases de Streptococcus thermophilus

Thermus Thermophilus -galactosidases in Α Production of Recombinant

Purifi cation and characterization of two phospho-β-galactosidases, LacG1 and LacG2, from Lactobacillus gasseri ATCC33323

Probiotics improve the intestinal microbiota and exert benefi ts for the host (Fuller, 1989; Parvez et al., 2006). Some strains of lactobacilli utilize lactose and alleviate lactose intolerance (Montalto et al., 2006). Lactobacillus gasseri is one of the predominant lactobacilli in the human intestine, and strains are used in probiotic foods. Lactobacillus gasseri is the major homofermentative ...

Purification and Properties of Human a-Galactosidases*

The thermolabile oc-galactosidase (cy-galactosidase A) and thermostable a-galactosidase (cr-galactosidase B) were separated and purified from human placenta. A homogeneous a-galactosidase B preparation was obtained, but the a-galactosidase A preparation contained small amounts of contaminating protein and various other acid hydrolase activities. Each preparation had a molecular weight of approx...

Profil épidémiologique des entérobactéries uropathogènes productrices de bêta-lactamases à spectre élargi

Les infections urinaires à entérobactéries productrices de bêtalactamases à spectre élargi (E-BLSE) constituent un risque infectieux, un enjeu thérapeutique de taille et peuvent même conduire dans certains cas à des impasses du fait de leur multi-résistance aux antibiotiques. Le but de ce travail est de préciser le profil épidémiologique des (E-BLSE) uropathogènes et décrire leur niveau actuel ...

Handwriting Trajectory Movements Controlled by a Bêta-Elliptic Model

This paper studies the dependence between geometry and kinematics in handwriting generation Movements. Based on a handwriting generation model developed earlier, movements parameters are extracted directly from on-line recording of velocity profiles. These parameters, which reflect dynamic process, are found to be highly related to the geometry of handwriting movements. The overall approach is ...
