Aliidiomarina minuta is a halophilic, alkaliphilic, aerobic and motile bacterium from the genus of Aliidiomarina which was first isolated from water from the Mono Lake from the United States.[1] Under adverse environmental conditions, A. marina shrinks to around 0.2 μm * 0.1 μm in size as a survival mechanism. This characteristic is unique to other species within the genus and gives A. marina the ability to pass through 0.22 μm filters (commonly used in filter sterilisation).
