Adopt a Bacterial Pigment: Violacein produced by Janthinobacterium lividum

The adopted bacterium produces violacein which appears as a dark purple, this bacterium is aerobic and a Gram negative organism. This bacterium is known as Janthinobacterium lividum. It inhabits soil and water, also feeds off carbohydrates (glycerol). Bacterial pigment can be used in various ways to benefits humans and the environment, some bacterial pigments are used in fashion industries such as developing new and interesting textile patterns and also used textile dye. Some bacterial pigments have health benefits such as in cancer.

Janthinobacterium lividum is 2.5 - 6 micrometers in size. In the picture above, its shape and pigmentation are displayed. This bacterium feeds off carbohydrates such as glycerol, which is used by the bacterium as a source of carbon. which is metabolized to produce a beautiful dark shade of purple.

Violacein and biofilm production in Janthinobacterium lividum - Pantanella - 2007 - Journal of Applied Microbiology -...

To analyse the environmental stimuli modulating violacein and biofilm production in Janthinobacterium lividum.

Microbiology from A to Z - Micropia

Pigment in microbes can have multiple functions. For example, it can be used for photosynthesis or for protections against UV light. However, this Janthinobacterium lividum bacterium uses its purple pigment as protection against other microbes. And this is not only useful for bacterium’s own survival, but also for animals working with him, like the red-backed salamander.

Bacteria Dye - work in process

short process of textile being dyed by bacteria, grid structure appears. the bacteria is called Janthinobacterium lividum and produces purple pigment. Violacein can be used as an alternative to synthetic dyes since it is biodegradable.

Violacein - a Textile dye

Violacein is an antioxidant, it is also known that it has anti-fungal and anti-bacterial effects. Violacein is the pigment produced by Janthinobacterium, it is used as a textile dye.
