Differential Characteristics of Bifidobacterium longum and Bifidobacterium animalis
Systematic and Applied Microbiology, 1991Summary Twenty five strains, which belong to Bifidobacterium animalis on the basis of their carbohydrate fermentation patterns, were isolated from human and calf feces. The DNAs of these strains were, however, completely homologous to the DNA of the type strain of Bifidobacterium longum .

Optimization of a Bifidobacterium longum production process
Journal of Biotechnology, 2005Bifidobacteria are used as probiotics mainly in the dairy industry as cell suspensions or as freeze-dried additives. So far there have been no reports on a thorough investigation on factors influencing the production process or a statistical approach to the optimization thereof.

Bifidobacterium longum is considered to play an important role in health maintenance of the human gastrointestinal tract. Probiotic properties of bifidobacterial isolates are strictly strain-dependent and reliable methods for the identification and discrimination of this species at both subspecies and strain levels are thus required.

The aim of this work was to construct a bifidobacterial biosensor that could be used to analyze the metabolic state of cells. We transformed by electroporation the human intestinal bacterium Bifidobacterium longum biovar longum with a vector (pGBL8b) containing the insect luciferase gene from a click beetle (Pyrophorus plagiophthalamus) and studied the

Molecular characterization of three plasmids from Bifidobacterium longum
Plasmid, 2004The complete nucleotide sequences for pNAC1 (3538bp) from strain RW048 as well as for pNAC2 (3684bp) and pNAC3 (10,224bp) from strain RW041 of Bifidobacterium longum were determined. The largest ORF (repB) of pNAC1 encodes a putative protein similar to those involved in a rolling-circle (RC) replication mechanism, which was confirmed by demonstration ...

Light sensitivity of Bifidobacterium longum in bioreactor cultivations
Biotechnology Letters, 2004Bifidobacteria are gaining commercial significance due to their probiotic properties. However, little is still known about the production of these bacteria and their behavior in bioreactors. Two Bifidobacterium longum strains were sensitive to light when grown in a transparent (glass) bioreactor under microaerophilic growth conditions (i.e.
