Bacteria from the Propionibacterium genus consists of two principal groups: cutaneous and
classical. Cutaneous Propionibacterium are considered primary pathogens to humans …

This review examines deoxyadenosylcobalamin (Ado-B12) biosynthesis, transport, use, and
uneven distribution among living forms. We describe how genetic analysis of enteric …

A biosensor is a measurement device or system that is composed of a biological sensing
component, which recognizes a chemical or physical change, coupled to a transducing …

The genetic modification of microorganisms is conducive to the selection of high-yield
producers of high-value-added chemicals, but a lack of genetic tools hinders the …

δ-aminolevulinate (ALA) is an important intermediate involved in tetrapyrrole synthesis
(precursor for vitamin B12, chlorophyll and heme) in vivo. It has been widely applied in …

Since the chemical synthesis of vitamin B12 requires more than 70 steps, the production of
vitamin B12 has been achieved by microorganism fermentation with additional brief …

Heme metabolism is central to blood-stage infection by the malaria parasite Plasmodium
falciparum. Parasites retain a heme biosynthesis pathway but do not require its activity …

Heme is an essential prosthetic group for many proteins involved in fundamental biological
processes in all three domains of life. In Eukaryota and Bacteria heme is formed via a …

Background Propionibacterium freudenreichii is a food grade bacterium that has gained
attention as a producer of appreciable amounts of cobalamin, a cobamide with activity of …

In a sense, propionic acid bacteria are domesticated bacteria. They might have been used
for cheese making as early as 9000 years Be. In the last 40 years their pmctical uses have …
