Methanomassiliicoccus luminyensis

Méditerranée Infection is the only institute developing research focusing on archaea associated to human flora.

Archaea are unicellular living organisms. These look like bacteria when examined under a microscope; however these have particular features within their outer wall as well as some specific metabolic characteristics.

Currently only three archaea were described in humans, which are all metanogenic archaea, meaning these can change hydrogen into methane gas.

Méditerranée Infection laboratory has discovered a new archaea which was named Methanomassiliicoccus luminyensis, whose image, got through electron microscope, appears on the headband of our homepage; the size of this archaea and the size of its genome are world records.
