Myxococcus llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochensis

Myxococcus llanfair­pwll­gwyn­gyll­go­gery­chwyrn­drobwll­llan­tysilio­gogo­goch­ensis is a gram-negative, rod-shaped species of myxobacteria found in soil.[1] It is a predator on other bacteria.

The ends of the rod-shaped vegetative cells taper slightly. The colonies are pale brown and show swarming motility. It produces orange, roughly spherical fruiting bodies. A draft sequence of its genome[2] showed significant differences from all previously known species of the genus Myxococcus.

It was isolated from soil collected near the settlement of Llanfair­pwll­gwyn­gyll­go­gery­chwyrn­drobwll­llan­tysilio­gogo­goch, on the island of Anglesey in North Wales, and was named after this location.

The scientific name of this bacterial species is considered the longest name in the binomial nomenclature system, bearing 73 characters in total. Despite this, it is not yet acknowledged by the International Journal of Systematic and Evolutionary Microbiology (IJSEM), and therefore is not considered to be valid. The current longest valid scientific name is Parastratiosphecomyia stratiosphecomyioides.[3]
