Description |
Photobacterium is a genus within the Family Vibrionaceae. These are
primarily marine organisms, hence require sodium for growth. They may be
free-living in the water, or found associated with fish. Hence, it thrives in
deep in the oceans as an extremophile where water pressure is so great it can
crush the bones. P. profundum is adopted as a model for piezophily
(Ref.1). The key to the bacterium s survival are genes that generate Omega-3
fatty acids–the heart-healthy stuff found in fish such as Salmon and several
such metabolites and enzymes present in the bacterium.
Glutathione is a
tripeptide, composed of glutamate, cysteine and glycine, and has numerous
important functions within the Photobacterium cell. This tripeptide is
specifically a thiol compound, present in [...] |
