Identification and characterization of a fructose phosphotransferase system in Bifidobacterium breve UCC2003

Article Abstract:

In silico analysis of the Bifidobacterium breve UCC2003 genome has helped in identifying the four genetic loci, each of which has specified a putative enzyme II (EII) protein of a phosphoenolpyruvate:sugar phosphotransferase system. Biochemical studies have shown that FruA has phosphorylated fructose at the C-6 position.

Low-pH adaptation and the acid tolerance response of Bifidobacterium longum biotype longum

Article Abstract:

Acid response and adaptation in a Bifidobacterium longum biotype longum and its acid-pH-resistant mutant are studied. The adaptation and response to low pH in Bifidobacterium longum biotype longum involve changes in the glycolytic flux and in the ability to regulate the internal pH.
