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 Endocarditis
Annals of Internal Medicine, 1975Excerpt Lactobacilli may grow very slowly or not at all in media commonly used for blood culture; in addition, these organisms may be moderately resistant to penicillin and difficult to eradicate f...

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

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 ...

Phage Susceptibility of Encapsulated Lactobacillus casei
Nature, 1965ONE 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 ...

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.

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.

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.

Antifungal activity of Lactobacillus casei and Lactobacillus brevis
57. hrvatski i 17. međunarodni Simpozij agronoma : zbornik radova, 2022Lactic acid bacteria (LAB) are indigenous and present in various substrates: soil, vegetables, meat, fermented products, etc. They are irreplaceable in dairy production and the feed industry. Antimicrobial metabolites are formed by LAB, and some of them have antifungal properties.
