Bifidobacteria are commensal bacteria, which naturally colonize the gastrointestinal tract of a large number of animals, including humans, contributing to their health and well-being. An important taxonomic marker for the identification of members of the bifidobacterial group is the presence of the fructose-6-phosphate phosphoketolase (F6PPK) activity. The F6PPK enzyme is involved in the bifidus shunt based on the ability of F6PPK to split fructose-6-phosphate into erythrose-4-phosphate and acetyl phosphate. Here, we describe the two main methods utilized to detect the presence of F6PPK activity, that is, the enzymatic assay and the presence of the D-xylulose-5-phosphate/fructose-6-phosphate phosphoketolase bifidobacterial gene.

Abstract

Bifidobacteria are commensal bacteria, which naturally colonize the gastrointestinal tract of a large number of animals, including humans, contributing to their health and well-being. An important taxonomic marker for the identification of members of the bifidobacterial group is the presence of the fructose-6-phosphate phosphoketolase (F6PPK) activity. The F6PPK enzyme is involved in the bifidus shunt based on the ability of F6PPK to split fructose-6-phosphate into erythrose-4-phosphate and acetyl phosphate. Here, we describe the two main methods utilized to detect the presence of F6PPK activity, that is, the enzymatic assay and the presence of the D-xylulose-5-phosphate/fructose-6-phosphate phosphoketolase bifidobacterial gene.
