متن کاملProteolysis by Lactobacillus casei
A study of the proteinase activity of Lactobacillus casei grown in milk and of cell-free extract of L. cawi has been reported on in a previous paper (Brandsaeter and Nelson, 1956). Whereas the proteinases of L. casei have been studied to some extent earlier, very little has been done to characterize the peptidases of this organism. Other lactobacilli hydrolyze some peptides (Christophersen and ...
متن کاملDiacetyl and acetoin production by Lactobacillus casei.
Agitation of broth cultures of Lactobacillus casei retarded cellular dry weight accumulation but enhanced production of both diacetyl and acetoin. Addition of pyruvate overcame this retardation, but addition of sulfhydryl-protecting reagents did not. Both pyruvate and citrate enhanced accumulated dry weight of L. casei incubated without agitation, but only pyruvate increased diacetyl accumulati...
متن کاملLactobacillus casei dihydrofolate reductase
1 The binding of a series of amide derivatives of methotrexate to Lactobacillus casei dihydrofolate reductase has been studied by inhibition constant measurements and by 'H n.m.r. spectroscopy. 2 Amide modification of the a-carboxylate of methotrexate was found to prevent interaction of the y-carboxylate with the imidazole of His 28. 3 Estimates of the contributions to the binding energy from t...
متن کاملCell surface characteristics of Lactobacillus casei subsp. casei, Lactobacillus paracasei subsp. paracasei, and Lactobacillus rhamnosus strains.
Hydrophilic and electrostatic cell surface properties of eight Lactobacillus strains were characterized by using the microbial adhesion to solvents method and microelectrophoresis, respectively. All strains appeared relatively hydrophilic. The strong microbial adhesion to chloroform, an acidic solvent, in comparison with microbial adhesion to hexadecane, an apolar n-alkane, demonstrated the par...
