Proteolysis 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 کاملCa2+-citrate uptake and metabolism in Lactobacillus casei ATCC 334.
The putative citrate metabolic pathway in Lactobacillus casei ATCC 334 consists of the transporter CitH, a proton symporter of the citrate-divalent metal ion family of transporters CitMHS, citrate lyase, and the membrane-bound oxaloacetate decarboxylase complex OAD-ABDH. Resting cells of Lactobacillus casei ATCC 334 metabolized citrate in complex with Ca(2+) and not as free citrate or the Mg(2+...
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 کاملAdditional observations on the rate of growth of Lactobacillus casei.
In the preceding paper (1) it was shown that the growth rate of Lactobacillus casei may be markedly affected by variations in the amount of asparagine present in the medium. This compound may be either stimulatory or inhibitory, depending upon the conditions existing; evidence was presented which indicates that asparagine is closely related metabolically to strepogenin. For example, strepogenin...
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...
