Respiration of Lactobacillus casei
Canadian Journal of Microbiology, 1968Although Lactobacillus casei is generally considered to be "indifferent" to oxygen, several strains exhibited considerable respiratory activity with a number of substrates related to carbohydrate catabolism. In many cases this respiratory ability enables the organism to utilize energy sources that would be unavailable under anaerobic conditions.

Lactobacillus casei response to pteroylpolyglutamates
Analytical Biochemistry, 1972Abstract The growth response of L. casei to pteroylpolyglutamates was investigated. The slope of the response curve varies with the number of glutamic acid residues present in the conjugate, becoming steeper for those forms with more than three glutamic residues. A greater concentration of these higher polyglutamates was needed for a given response

Phage Susceptibility of Encapsulated Lactobacillus casei [PDF]
Nature, 1965 ONE of the principal factors which determines the susceptibility of a given bacterium to attack by bacteriophage is the availability of specific surface receptor sites. Numerous investigators have observed that encapsulated bacteria are generally phage resistant, and it has been assumed that the capsular layer, interposed as a physical barrier between ...

Diacetyl reductase of Lactobacillus casei
Canadian Journal of Microbiology, 1970Diacetyl reductase (diacetyl:reduced nicotinamide adenine dinucleotide (NADH) oxidoreductase, EC. 1.1.1.5) has been isolated from Lactobacillus casei. Cell sonication, ammonium sulfate fractionation, Sephadex gel filtration, DEAE-cellulose chromatography, and alumina gel adsorption were used to obtain the partially purified enzyme.

The effects of 6-mercaptopurine on Lactobacillus casei
Archives of Biochemistry and Biophysics, 1957Abstract The inhibitory action of 6-mercaptopurine has been shown to be manifested by an interference with purine interconversion. The incorporation of adenine and of adenylic acid are affected in different ways by 6-mercaptopurine. These facts have been fitted to a schematic representation of a purine interconversion cycle compatible with the known ...

Genetic transformation of Lactobacillus casei by electroporation
Biochimie, 1990Lactobacillus casei IAM1045 was transformed with a plasmid pAM beta 1-1, a tra deleted derivative of pAM beta 1, by electroporation. Effective transformation was achieved in electroporation buffers of a wide range of pH values, and in all phases of cell growth tested, with highest frequency in the early log phase.

Peptidase profiling of Lactobacillus casei
Biotechnology Techniques, 1993Fifty four Lactobacillus casei strains were investigated and compared for their peptidase profiling by statistical analysis of aminoacids released from milk proteins. Forty one strains formed a homogeneous group; only two strains, not included in the above group, resulted the most suitable for grana cheese production either for their aminoacidic ...

Transport of folate compounds into Lactobacillus casei
Archives of Biochemistry and Biophysics, 1974Abstract Transport of folate, 5-methyl tetrahydrofolate, and amethopterin into Lactobacillus casei occurs against a concentration gradient, is pH and temperature dependent, requires glucose, exhibits saturation kinetics, is maximal when cells are harvested in late-log phase, and is repressed by excess folate in the growth medium.
