Victivallis vadensis is a Gram-negative, coccus-shaped, bacteria found in the human digestive tract.
It was later renamed for an area in the Netherlands, known as “Food Valley”, near the scientists at Wageningen University, who first identified the organism.
This microbe, taken from a human fecal sample, was first cultured in the Netherlands at an optimal temperature of 37 degrees Celsius and 6.5 pH.
Researchers there discovered that it grows best in liquid or soft agar with one of the following sugars: cellobiose, fructose, galactose, glucose, lactose, lactulose, maltose, maltotriose, mannitol, melibiose, myo-inositol, raftilose, rhamnose, ribose, sucrose and zylose, [2] which it uses fermentatively.
[2] Victivallis vadensis forms a slime layer outside of its cell membrane,[2] which appears halo-like when examined microscopically.
