Vibrio sp. Azasii | |
Vibrio azasii (Vibrio sp. Azasii)[1] is a bioluminescent bacterium belonging to vibrio spp. It is a Gram-negative bacterium possessing a curved rod shape (comma shape) and moves by means of flagella.
Research has been done with V. azasii as a sustainable source of bioluminescence as an alternative to electric streetlights.[citation needed] They are photosynthetic, so as long as a healthy population could be sustained, they could be a feasible option for sustainable lighting. The bioluminescence produced is not bright enough to serve as indoor lighting, however, streetlights do not need to be very bright to serve their function.
Vibrio bacteria are oxidase positive facultative anaerobes [2] Oxidase positive bacteria can use oxygen as the final electron acceptor in the electron transport chain. Facultative anaerobes can use oxygen or they can use fermentation to generate ATP. Lights made with V. azasii would be able to use oxygen freely without the need to create an anaerobic chamber.
Vibrio bacterium also have two distinct chromosomes, a large and small circular chromosome.[3] The genes on the larger chromosome contain all the essentials that are needed for life. The smaller chromosome contains genes that code for environmental responses. [3] The large chromosome is consistent in length across most of the genus, however the smaller one has varying length. [3] Bioluminesence is important for V. azasii , and would not likely be present on the smaller chromosome, because it could be lost during horizontal gene transfer.
